Abstract

A center of gravity (C/G) control system for a vehicle includes sensors to measure the center of gravity shift and mass shift of the human body in relation to the vehicle, a controller to determine outputs, a dynamically adjustable vehicle system, and a power supply. The sensor measures the direction and rate of shift of the center of gravity and mass shift of the human and creates a representative input signal. The controller determines the appropriate outputs in response to the relative center of gravity shift data received. The dynamically adjustable vehicle system receives the controller output and performs the expected action.

Description

REFERENCE TO RELATED APPLICATION

The present application is the subject of provisional application Ser. No. 60/280,851 filed Apr. 3, 2001 entitled SUSPENSION SYSTEM FOR VEHICLES FOR TRANSPORTING A HUMAN BODY.

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention-relates to vehicles, specifically to improve passenger/payload positioning by using a enter of gravity and mass shift control system.
2. Description of the Prior Art
Prior art has focused on the effect the regular and irregular surfaces of the ground has on the vehicle and thus to the passenger through the vehicle to passenger contact points. Prior art focuses on adjusting the vehicle system's alignment to the ground to reduce abrupt changes in position of the vehicle to passenger contact points.
Prior art does not attempt to directly control the passenger center of gravity or mass except by indirect methods.
Prior art consists of automotive, motorcycle, bicycle and the like, designs that react after contacting an irregular surface in the vehicle path by releasing stored energy in suspension systems. Examples are the bicycle suspension systems disclosed in U.S. Pat. No. 4,881,750 to Hartmann, U.S. Pat. Nos. 5,445,401 and 5,509,677 to Bradbury, U.S. Pat. Nos. 5,456,480 and 5,580,075 to Turner, et al. The prior suspension systems during use are preset and not adjustable so these are passive or static suspension systems. The suspension may be too harsh or too soft for the surface conditions.
Prior art consists of automobile and bicycle suspension designs that react to the contact of an irregular surface and are controlled by measuring the rate of travel or the distance traveled by the device itself. Examples are the front bicycle suspension shocks that operate valves based on the speed of the shock piston shaft as disclosed in U.S. Pat. No. 6,026,939 to Girvin and Jones, as disclosed in U.S. Pat. No. 6,149,174 to Bohn, and automobile wheel suspension that is stiffened under increased loads from cornering as disclosed in U.S. Pat. No. 5,217,246 to Williams, et al. The above-cited systems are semi-active systems limited to the switching between two positions of hard and soft.
Prior art also includes designs that measure movement and timing of the suspension device after contacting an irregular surface then calculate the reaction with a preprogrammed controller that is limited in scope and without user input. One example of this system is disclosed in U.S. Pat. No. 5,911,768 to Sasaki. The above cited system is an active system and yet still limited by the preprogrammed controller.
Prior art also includes designs that measure movement of the C/G of the passenger/payload balanced above and rotated around a single axle restricting the C/G movement to a limited arc along one lateral plane as cited in U.S. Pat. No. 5,975,225 to Kamen, et al., as cited by the papers by Voss et al., “Dynamics and Nonlinear Adaptive Control of an Autonomous Unicycle—Theory and Experiment”, American Institute of Aeronautics and Astronautics, A90-26772 10-39, Washington, D.C. (1990), pp. 487-494 (Abstract only) and Koyanagi et al. “A Wheeled Inverse Pendulum Type Self-Contained Mobile Robot and its Two Dimensional Trajectory Control”, Proceeding of the Second International Symposium on Measurement and Control in Robotics, Japan (1992), pp. 891-898.
Prior art of the suspension systems disclosed earlier are based on the relationship of the contact points between the vehicle and the ground. The vehicle contact points to the passenger/payload are measured last or ignored all together. The range of motion of the C/G shifting in relationship to the constraints of the vehicle's passenger contact points has not been considered. Prior art control systems disclosed earlier focused on the measurement of the distance traveled or the rate of speed of the suspension devices themselves. The ride characteristics encountered by the center of gravity and mass shift of the passenger is two systems or linkages away from the attempted control points.
Prior art control systems disclosed earlier that appear to use center of gravity and mass shift measurements for control are actually measuring the pitch (lateral movement in one plane x) of a plate or body mounted above a single axle. The theoretical center of gravity is a gross approximation using this method. The inverse pendulum balancing method does work to place the center of gravity y-axis plane over the axle by moving the vehicle forward or back in a continuous recovery from a falling state. The C/G and mass elevation position in the Z-plane is disregarded and yet the height of the actual center of mass above the axle has a great influence on the effectiveness of the drive and balancing system. The single axle, single pendulum control method also has a weakness when encountering irregular surfaces that are soft or severely irregular. Power is applied through the wheels to continually adjust the location of the axle under the center of gravity. The reactive control has difficulty in keeping a constant power balance when a vehicle wheel has lost traction. An interactive center of gravity and mass shift control system that incorporated the measurement of the position of the center of gravity and mass in multiple planes would help prevent the over rotation of the center of gravity y plane at increased speeds.
Prior art active suspension systems based on ground induced input systems are not active in relationship to the actual rider position. All the prior active systems have focused on measuring the velocity or stroke (travel delta) of the suspension and then creating an output signal. The inputs have been velocity or travel measuring devices to a control circuit that outputs back to the original suspension devices. The advantage of the center of gravity and mass shift control system controlling a dynamically attached suspension system is the active relationship to the rider position.

SUMMARY OF THE INVENTION

The present invention provides a control system for improving the ride characteristics for a vehicle transporting a human body and or payload by:

- (a) obtaining from a set of sensor means, a signal to denote the position of the center of gravity and mass shift of the human body;
- (b) determining from the set of relative center of gravity inputs a set of estimated absolute center of gravity and mass shift values in relation to the vehicle;
- (c) deriving an output control signal from the said set of center of gravity and mass shift values; and
- (d) applying the output control signal to a vehicle system effecting a ride characteristic.

The sensor means actively measures the center of gravity and mass shift of the human body in relation to the vehicle wherein the set of center of gravity and mass shift signals will be input into the control system to comprise estimated values for output signals:

- (a) sensors determine direction of the center of gravity and mass shift and the rate of shift.
- (b) sensors may be located on the human body in the same manner as a wristwatch, on the vehicle, or on a system external to the vehicle.
- (c) sensors may be of different forms including accelerometers, strain gauges, gyroscopes (single and multi-axis), inclinometers, capacitive extensiometers, load cells, pressure gauges, rotational gages, positional gages, magnetic devices, optical, laser, sonar, ultrasonic, infrared (IR), velocity, light emitting diodes (LED), Hall's Effect sensors, vibration gages, temperature gauges, transducers, user input switches, preprogrammed computer programs, voice, satellite Global Positioning System, and the like (wired or wireless sensor systems included).

The present invention enables the use of a control system using an electronic control module that has the ability to be preprogrammed, reprogrammed, adjusted during use, have multiple programs installed, have programs upgraded as human skills increase, have a learn mode, an interactive mode with other electronic control modules, and have an indeterminate number of variables available for user selection.
The present invention will be able to attain an interactive process through the control system electronic controller module to:

- (a) allow pre-programmed input data,
- (b) allow adjusting to interactive data during use,
- (c) allow for external variables to be considered during operation of the device,
- (d) establish parameters that can be modified while in use,
- (e) create parameters based on changing weather,
- (f) preset parameters for travel or speed limits
- (g) create parameters biased for safety based on ability level of user
- (h) monitor parameters that can activate a warning light or other safety systems.

The invention control system allows the human center of gravity and mass shift values to control vehicle systems over irregular surfaces.
These and other advantages are achieved by this invention in a vehicle shifting control system by obtaining from sensors mounted on the vehicle to sense center of gravity and mass shift of the human body even during vehicular use over level regular surfaces. A set of relative center of gravity and mass shift signals based on the determined change in the center of gravity and mass shift of a standing or sprinting human body can produce signals to lock out a suspension device or lock in a shifting device to eliminate inadvertent shifts.
These and other advantages are achieved by this invention in a vehicle braking system by (a) obtaining from sensors, mounted on the vehicle to sense the center of gravity and mass shift of the human body a set of relative center of gravity and mass signals; (b) determine from the set of relative signals a set of estimated absolute body center of gravity and mass; and (c) control a brake system responsive to the determined set of estimated body center of gravity and mass position signals.
These and other advantages are achieved by this invention in a vehicle adjustable geometry system by (a) obtaining from sensors, mounted on the vehicle to sense the center of gravity and mass shift of the human body a set of relative center of gravity and mass signals; (b) determine from the set of relative signals a set of estimated absolute body center of gravity and mass; and (c) control an adjustable vehicle geometry system responsive to the determined set of estimated body center of gravity and mass position signals.
These and other advantages are achieved by this invention in a vehicle power system by (a) obtaining from sensors, mounted on the vehicle to sense the center of gravity and mass shift of the human body a set of relative center of gravity and mass signals; (b) determine from the set of relative signals a set of estimated absolute body center of gravity and mass; and (c) control an adjustable power system responsive to the determined set of estimated body center of gravity and mass position signals.
These and other advantages are achieved by this invention in a safety system by (a) obtaining from sensors, mounted on the vehicle to sense the center of gravity and mass shift of the human body a set of relative center of gravity and mass signals; (b) determine from the set of relative signals a set of estimated absolute body center of gravity and mass; and (c) control a safety system responsive to the determined set of estimated body center of gravity and mass position signals. The above safety system can include warning lights, warning siren, external lights, anti-lock brake circuit, external cornering wheels, and the like.
These and other advantages are achieved by this invention in a steering control system by (a) obtaining from sensors, mounted on the vehicle to sense the center of gravity and mass shift of the human body a set of relative center of gravity and mass signals; (b) determine from the set of relative signals a set of estimated absolute body center of gravity and mass; and (c) control a steering control system responsive to the determined set of estimated body center of gravity and mass position signals.
These and other advantages are achieved by this invention in a data acquisition system by (a) obtaining from sensors, mounted on the vehicle to sense the center of gravity and mass shift of the human body a set of relative center of gravity and mass signals; (b) determine from the set of relative signals a set of estimated absolute body center of gravity and mass; and (c) control a data acquisition system responsive to the determined set of estimated body center of gravity and mass position signals. The data acquisition system can be used to develop virtual reality game data, interactivity with group of other units on stationary exercise equipment, inputs from professional riders for training evaluations, inputs from professional riders for downloading to interactive personal computer programs, and amusement or destination vehicle park interactive packages.
The advantages of the center of gravity (C/G) control systems is to use the C/G and mass shift to control the vehicle systems, regardless of the limitations of the contact points to the vehicle, or the vehicle to ground contact points. Example: C/G and mass shift of passenger/payload is monitored, passenger has a free range of motion within the constraints of the contact points to the vehicle, and the vehicle has contact points to a regular or irregular surface. A control system based on the C/G and mass shift sends outputs to one or more of the vehicle systems. The C/G and mass shift control system is an interactive system. The passenger is able to input variable data into the base control program (BCP). A C/G and mass shift sensor on the vehicle can input data into the BCP. A C/G and mass shift sensor located off the vehicle can input data into the BCP via telemetry or infrared wireless systems.
The advantage of the center of gravity and mass control system is the ability to adapt formulas based on Human/Payload to Vehicle Mass ratios, center of gravity and mass shifts, and their effects as rate, and vector. The center of gravity and mass formulas can also be influenced by inputs from a human pertaining to: weight of human body, height of human body, shape of human body, pedal cadence parameter, riding position parameter, style of riding parameters, terrain parameters, speed parameters, power output parameters, input from cycle computer, input from heart monitor, bike geometry parameters, brake system parameters, drive system parameters, and the like.
An additional advantage of the control system is the ability for the system to be used with current devices and interactive devices co-operatively. The active control is able to take in combinations of human inputs and reactive devices, interlocked or independent. The system will allow adaptability to current vehicles as add-on and upgradeable devices.
Additional advantages of the control system will be the ease of adaptability for use with existing vehicular control systems and devices including but not limited to manual suspension lockout systems, automatic drive indexing systems, current bicycle and motorcycle frame geometries with and without rear pivots, and other available existing control systems. The advantages of using the INTERACTIVE human center of gravity and mass shift controls are that terrain is not required to be the initiator of the vehicle's dynamic systems.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a diagrammatic representation of a center of gravity shift and mass shift control system apparatus, which can function as a control system for a two wheeled personal vehicle front suspension. Control system 1 a receives input signal 1D from C/G shift sensor device 1 c. Control system 1 a processes the input signal 1 d and provides an output signal to an attached dynamic system 1 f of a vehicle. The control system 1A has a power supply 1B. A manual input device 1 e sends data for modification of control parameters incorporated in control system 1 a.
FIG. 2 is a side view of a C/G and mass shift control system apparatus as described in FIG. 1 installed on a bicycle with an attached dynamic front suspension assembly 2 d. The control system 2 m senses the movement of C/G and mass shifts in the conical representation area of 2 a. The Center of wheelbase of the vehicle is represented by line 2 p. Human contact points to the vehicle are defined as seat contact location 2 c, foot contact location 2 f, and hand contact location 2 e. The representation of the pivot point of a human seated 2 b is the focal point of the human range of motion in the ‘x’ plane (forward and back) and the focal point for the conical range of motion for all other planes. The suspension movement 2 j is the reaction of the vehicle when the front suspension assembly means 2 d is active. The C/G shift and mass shift vector 2 g is represented by force vector arrow 2 g.
FIG. 3A is an exploded isometric view of the front wheel suspension dynamic device 2 d introduced in FIG. 2 using a mechanical system sensor. A handle bar clamp 1 is attached to a handle bar clamp body 2 by attachment bolts 3 designed to hold a common bicycle handle bar. The handle bar clamp body 2 pivots on upper link bushings 7 around the upper link pivot rod 6 supported by the front of upper link 8. Lower link 5 with installed lower link bushing 4 connects to handle bar clamp body 2 and pivots freely as the lower link bushing 4 rests on the lower link pivot pin 48. Upper steerer clamp with shock mount 9 pivots freely about an upper link pivot 6 located in the center of upper link 8 and is clamped to the top of steerer 33 by a lower link attachment bolt 11. Right stanchion upper link mount 12BB and left stanchion upper link mounts 12AA are connected to the long open end of upper link 8 by an upper link attachment bolt 13. Shock absorber 10 is connected to the upper steerer clamp with shock mount 9 by a lower link attachment bolt 11. Main pivot bushing 17 and main pivot rod 16 are clamped into the lower steerer main pivot clamp 19 by main pivot attachment bolts 15. (FIG. 3B illustrates spring member assembly 18 as an optional replacement for main pivot bushing 17 and main pivot rod 16.) Lower steerer main pivot clamp 19 is secured to the lower end of steerer 33. Left pivot clamp with brake rod mount 20 is attached to the main pivot rod 16 by left pivot attachment bolt 46 and right pivot clamp 21 is attached to the main pivot rod 16 by right pivot clamp attachment bolt 47. Right pivot bushing 22 is secured into right stanchion clamp 28BB and fits around right pivot rod 23 which is clamped to right pivot clamp 21 with right pivot attachment bolts 47. The left pivot rod 24 is clamped into the left pivot clamp with brake rod mount 20 with left pivot clamp bolts 46. The other end of left pivot rod 24 is inserted into left pivot bushing 25 which is secured into left stanchion clamp 28AA. Right stanchion upper link mount 12BB is secured to the top end of right stanchion 32 and right stanchion lower attachment 37 is secured to the bottom end of right stanchion 32. Left stanchion upper link mount 12AA is secured to the top end of left stanchion 31 and left stanchion lower attachment 35 is secured to the bottom end of left stanchion 31. The stanchion brace plate 30 provides the spacing required for the correct width of the stanchions 31 and 32, for torsional resistance of the entire assembly to twisting forces, structural stiffness by creating a bridge between the two legs, and is clamped to the stanchions 31 and 32 at the correct height by stanchion clamp bolts 29. The kinetic energy of the vehicle is transferred by the brake transfer rod 27 connected to the end of left pivot clamp with brake end mount 20 by the transfer rod bolt 26 and to the brake adapter arm 39 by brake connector bolt 41 during braking to increase spring rate to resist the downward force created by a forward C/G shift. A prior art front disc brake system 49 is attached to the brake energy transfer adapter arm 39 with brake connector bolts 41. The hub with brake disc 44 is supported by the hub axle 45 which is clamped at one end to the left stanchion lower attachment 35 by the left stanchion lower attachment bolt 36 and is clamped at the other end to the right stanchion lower attachment 37 by the right stanchion lower attachment bolts 38. The brake energy transfer adapter arm 39 is free to pivot around brake pivot bushing 42 which is held in place by brake pivot guide 43 mounted on hub axle 45. The lower end of shock absorber 10 is connected to the stanchion brace plate 30 by pivot connector bolt 40.

FIG. 4 is a side view of an assembled front suspension assembly 4 x consisting of a front suspension assembly as shown in FIG. 3A, a C/G and mass shift control system device 4 b, and a C/G and mass shift sensor device 4 c. The C/G and mass shift control system 4 b measures changes in the C/G position 2 a of a rider as represented in FIG. 2. The C/G and mass shift sensor device 4 c sends inputs to the C/G shift control system 4 b to output control signals to the front suspension assembly 2 d.
FIGS. 5A-8B are side elevational views of the suspension assembly 2 d which illustrate the advantage of the unique application of multiple pivot locations on the front suspension assembly 2 d shown in FIG. 3A and they illustrate different positions of the assembly during the suspension action. In FIGS. 5A-8B, the left view is the left stanchion and the right view is a cut away view of the centerline of the vehicle head tube 3AA and the main pivot 4AA. (In FIGS. 5A, 6A, 7A AND 8A, the shock absorber 10 is removed to show the pivoting action of the assembly more clearly.) The C/G shift control system is mechanically introduced to the assembly through the connection of the rider's arms. As the rider shifts his mass and thus C/G, his arms 9 n connected at the position 2 e as illustrated in FIG. 2 transfer the mass shift vector 2 g to the suspension assembly 2 d through the handle bar connection at the end of 2BB as shown in FIGS. 5A and 5B. The present invention offers many advantages over existing front suspension systems. The combination of a hinged upper link 8 and hinged lower legs 1AA and 1BB provides a leveraged advantage for a front suspension travel system. The leverage of the upper hinge provides a distinct benefit during small rapid suspension movements. The handlebar clamp body 2 is able to absorb a majority of the small rapid impact forces with a small un-weighting of the handlebar by the rider while prior art designs must choose a pre-set spring rate. With no mechanical leverage one advantage of this front suspension assembly embodiment is the amount of suspension travel gained by the leverage and pivoting action of the upper link assembly as represented by 2AA and 2BB. The main pivot bushing 17 which supports the lower leg right and left pivot clamps, 20 and 21 respectively, is secured in the lower steerer clamp 19 which is positioned in place at the bottom of the vehicle head tube 3BB. The upper steerer clamp with shock mount 9 is located at the top end of the head tube 3BB. The upper link 8 pivots on the upper pivot 6 that is clamped in the upper steer clamp 9. In this way, the front suspension works as two systems working together as one integrated assembly. The upper link leverage and the lower leg pivot rotation provide compliant movement to a response for short travel impact forces and provides long travel movement to absorb large impacts as well.
Thus, there has been provided a human and/or payload transport vehicle shown in FIGS. 5A-8B which has a ride characteristic adjustment mechanism, sensor apparatus for sensing the center of gravity position and mass shift of said human and/or payload relative to said vehicle and producing signals corresponding thereto and means coupling said signals to said ride adjustment mechanism to adjust the ride characteristic of said vehicle.
FIG. 9 is a side elevation view of the operative embodiment of converting the measurement of the center of gravity in cone 2 a and mass shift vector 2 g of the body by the control system 2 m to the activation of the front suspension assembly 2 d introduced in FIG. 2. The vehicle center of wheelbase 2 p reference is normally located between front wheel 9 r and rear wheel 9 s during seated riding. The dotted area 9 e is the representative envelope of the seated cyclist's reciprocating leg movement when pedaling, while force vectors 9 a, 9 b, 9 c, and 9 d are representations of the four phases of the pedaling cycle—build up, power, return, and coast respectively. The leg positions of the human range of motion during seated pedaling are upper leg position 9 f, middle leg position 9 g, and lower leg position 9 h and these develop the inertia 9 i which creates a force vector 9 t transferred into the vehicle frame structure 9 l through the bottom bracket 9 j which is connected to the cyclist's legs through pedal connecting points 2 f. The inertia 9 i transferred into bottom bracket 9 j then creates a rotational force 9 m on the front suspension assembly 2 d multiple pivot points. The arms of the rider 9 n form the linkage of the center of gravity 2 a and mass shift vector 2 g to the front suspension assembly 2 d through the connecting point 2 e. The rotational forces 9 m being transferred through front suspension assembly 2 d pivots are counterbalanced by the front suspension spring (in shock absorber 10) compression during the pedaling phases 9 a, 9 b, 9 c, and 9 d; this is represented by the force vectors 9 p at the connection point 2 e.
FIG. 10 is a side elevation view of the operative embodiment of converting the measurement of the center of gravity in cone 2 a and mass shift vector 2 g of the body by the control system 2 m into activation of the front suspension assembly 2 d introduced in FIG. 2 for a standing pedaling rider. The vehicle center of wheelbase 2 p reference is normally located behind the front wheel 9 r and close to the rear wheel 9 s during standing riding. The dotted area 10 e is the representative envelope of the cyclist's reciprocating leg movement and upper torso shift when pedaling, while force vectors 9 a, 9 b, 9 c, and 9 d (e.g. pedaling phases) are representations of the four phases of the pedaling cycle—build up, power, return, and coast respectively. The shifting of the mass during standing pedaling causes the creation of a large downward inertia 10 i which causes the force vector 9 t to transfer into the vehicle frame structure 9 l through the bottom bracket 9 j connected to the cyclist's legs through pedal connecting points 2 f. The inertia 10 i transferred into bottom bracket 9 j then creates a rotational force 9 m on the front suspension assembly 2 d multiple pivot points. The arms of the rider 9 n form a transfer linkage from the center of gravity 2 a and mass shift 2 g to the front suspension assembly 2 d through the connecting point 2 e. The rotational forces 9 m being transferred through the front suspension assembly 2 d pivots are counterbalanced during the pedaling phases 9 a, 9 b, 9 c, and 9 d by the front suspension spring compression force; this is represented by the force vectors 9 p at the connection point 2 e. The rider exerts a force 10 f as he pulls on the handlebar connection 2 e to assist in balancing as he performs the pedal cycle. The standing riding position only uses two of the rider connecting points, 2 e at the hands, and 2 f, at the feet, and this mode creates a taller center of gravity cone 2 a to measure as the 2 a focal point originates in effect at the 9 j bottom bracket.
FIG. 11 is a side elevation view of the operative embodiment converting the measurement of the center of gravity in cone 2 a and mass shift 2 g of the body by the control system 2 m into activation of the front suspension assembly 2 d introduced in FIG. 2 for a standing braking rider. The vehicle center of wheelbase 2 p reference is normally located centered between the front wheel 9 r and the rear wheel 9 s during standing braking. The dotted area 11 e is the representative envelope of the cyclist's leg movement and upper torso shift area when braking. The arms of the rider 9 n form the transfer linkage of the center of gravity 2 a and mass shift vector 2 g to the front suspension assembly 2 d through the connecting point 2 e. The braking function causes a force vector at the rear brake caliper 11 a and a force vector 11 b along the attached brake energy transfer rod 27. The force vector 11 b causes rotation vector forces 9 m at the front suspension assembly 2 d pivots which assists the front suspension spring rate. When the forward mass shift 2 g of the rider occurs, the mass shift 2 g acting through the connecting arms 9 n of the rider to the front suspension assembly 2 d effectively provides neutralized force vectors 11 c and 9 p. The shifting of the mass 2 g during standing braking causes the rotation of energy around the rear dropout 9 u which is the center of the wheel 9 s. The braking forces are transferred by the brake energy transfer rod 27 and this assists the front suspension compression spring force which creates a counterbalanced force vector 9 t that is loading the frame 9 l through the bottom bracket 9 j connected to the cyclist's legs through pedal connecting points 2 f. The standing braking position only uses two of the rider connecting points, 2 e at the hands, and 2 f at the feet, and this creates a taller center of gravity cone 2 a to measure as the 2 a focal point originates in effect at the 9 j bottom bracket.
FIG. 12 is a side elevation view of the operative embodiment of converting the measurement of the center of gravity in cone 2 a and mass shift 2 g of the body by the control system 2 m to the activation of the front suspension assembly 2 d introduced in FIG. 2 for a sitting rider who encounters an obstacle such as rock 12 d. The vehicle center of wheelbase 2 p reference is normally located centrally between the front wheel 9 r and the rear wheel 9 s during riding in a seated position. The dotted area 12 a is the representative envelope of the cyclist's leg movement and upper torso shift when riding over an obstacle. The vector force 12 b is from the impact of wheel 9 r with rock 12 d. The impact causes a forward mass shift 2 g which rotates around the rear dropout 9 u which is the center of the wheel 9 s. The arms of the rider 9 n form the linkage of the center of gravity 2 a and mass shift 2 g to the front suspension system 2 d through the connecting point 2 e. The mass shift 2 g created by the vector force 12 b in the forward direction transfers through the connecting point 2 e which causes the front suspension assembly 2 d to shorten in length and the connecting point 2 e to lower which absorbs the forward shift 2 g of the rider as shown by the force vector 9 p location. The rotational forces 9 m are transferred through the front suspension assembly 2 d pivots as the wheel 9 r moves to wheel location 12 c. The changing of length of the assembly 2 d allows the frame 9 l to achieve a neutral position represented by force vectors 9 t. The sitting riding position uses three rider connecting points, 2 e at the hands, 2 f at the feet, and 2 c at the seat where the focal point 2 b for the center of gravity cone 2 a is located.
FIG. 13 is a side elevation view of the operative embodiment of converting the measurement of the center of gravity in cone 2 a and mass shift 2 g of the body by the control system 2 m to the activation of the front suspension system 2 d introduced in FIG. 2 for a seated rider who encounters a rapid sequence of small obstacles such as rocks 13 d. The vehicle center of wheelbase 2 p reference is normally located centrally between the front wheel 9 r and the rear wheel 9 s during riding in a seated position. The dotted area 13 a is the representative envelope of the cyclist's leg movement and upper torso shift when riding over a rapid sequence of small obstacles. The vector force 13 b is from the impact of wheel 9 r with rocks 13 d. The vector force 13 b causes a forward mass shift 2 g which rotates around the rear dropout 9 u which is the center of the wheel 9 s. The arms of the rider 9 n form a linkage to the center of gravity cone 2 a and mass shift vector 2 g and allows the transfer of the mass shift vector 2 g to the front suspension assembly 2 d through the connecting point 2 e. The load transfer of the mass shift causes the front suspension assembly 2 d to shorten in length and the connecting point 2 e to lower which absorbs the forward shift 2 g of the rider as shown by the force vector 9 p location. The rotational forces 9 m are transferred through the front suspension assembly 2 d pivots as the wheel 9 r moves to wheel location 13 c. The changing of length of the front suspension assembly 2 d allows the frame 9 l to achieve a neutral position represented by force vectors 9 t. The seated riding position uses three rider connecting points, 2 e at the hands, 2 f at the feet, and 2 c at the seat where the focal point 2 b for the center of gravity cone 2 a is located.
FIG. 14 is the side elevation view of a bicycle using the front suspension assembly 2 d in FIG. 2 in a compressed and uncompressed position for geometric comparison versus prior art suspension devices to show the handling benefits of the suspension system design. Two unique benefits of the embodiment of the front suspension assembly 2 d is that the vehicle wheelbase will only shorten in length approximately 25 mm as shown by head tube angle measurements 14D and 14C which allows for stable vehicle handling and, second, the head tube angle and height will not change drastically during the length of stroke of the suspension action. As a large change in head tube angle will adversely affect the ride characteristics of the vehicle by causing inefficient and delayed steering response angles for the vehicle steering assembly, this design minimizes this adverse effect to a greater degree than current front suspension systems as shown by head tube angle measurement 14I. Note the rotational change 14J (16.1 degree) in brake adapter location. The front suspension assembly handlebar position change is capable of 75 mm of travel as shown by measurements 14G and 14H. This allows the front suspension design to absorb a C/G and mass shift well without decreasing other important ride characteristics of the vehicle. Measurements 14E and 14F for the change in bottom bracket height and measurements 14A and 14B for the seat position change show that the change in the front suspension position is not adversely affecting these key ride characteristics.
FIG. 15 is the side elevation view displaying the vehicle to rider contact points, the system linkages to the upper torso, and the initial approximate center of gravity position of a human sitting on a bicycle. The common contact points for a human rider to a bicycle are hand location 2 e, seat location 2 c, and foot location 2 f. The arms of the rider 9 n are a link between the hand location 2 e and the upper torso 15 a. The seated rider upper torso 15 a will pivot at the torso seat location 2 b. The upper torso 15 d has a link 15 b between the upper torso 15 a and seat pivot 2 b. The lower torso is connected between the seat pivot 2 b and the foot location 2 f by links 15 c. The lower torso range of motion is represented by 9 v. A C/G shift control system 2 m monitors the movement of the upper torso 15 d in the center of gravity zone 2 a and the movement of the torso is represented as mass shift 2 g. The C/G shift control system 2 m will send output signals to attached dynamic systems such as a dynamic front suspension system assembly 15 e. The C/G shift control system 2 m outputs may be sent to attached dynamic devices such as front suspension 15 e and others through electrical wire harness, by wireless electrical, hydraulic, pneumatic, mechanical, and the like.
FIG. 16 is the side elevation view displaying the bicycle contact points and linkages to the upper torso approximate center of gravity position of a human standing on a bicycle with one foot above the other in line with the body vertically.

Link 15 c is a representation of the connection of the bottom bracket 9 j and the seat pivot 2 b and link 15 b is the connection from seat pivot 2 b to the upper torso arm pivot 15 a. The upper torso pivot 15 a is connected to the hand connection location 2 e by arm link 9 n. Control system 2 m will measure the C/G shift area 2 a for mass shift vector 2 g then send appropriate output signals to front suspension assembly system 15 e.
FIG. 17 is the side elevation view displaying the bicycle contact points and linkages to the upper torso approximate center of gravity position of a human standing on a bicycle with the feet parallel to the ground plane while riding. The position of the rider affects the C/G shift area 2 a as the seat pivot 2 b is located farther away from the vehicle centerline. The lower connecting link 15 c and torso connecting link 15 b are at a greater angle than when sitting. The mass shift 2 g is more dynamic and responsive to the vehicle movements. The benefit of the present invention is apparent as the C/G shift control system 2 m controls the attached device 15 e to respond to any C/G shifts 2 a and mass shifts 2 g.

Exact sensor positions can vary dependent on the size and shape of the vehicle, the type of sensor used, and the contact points available with the human rider. Sensor mounting methods to the vehicle will be dependent on size and type of sensor used. The sensors may use wire harness assemblies or wireless outputs such as infrared to send signals to the C/G shift system controller 4 b.
FIG. 20 is the side elevation view of a bicycle having multiple suspension systems to which the control system of the present invention is applied. The bicycle may have one, two, three, or more suspension system means that work independently from each other or interdependently based on the controller mechanism chosen.

Front suspension assembly 20 a, front frame suspension assembly 20 d, rear suspension assembly 20 b, and seat suspension assembly 20 c are all controlled by the C/G shift controller 4 b. As the C/G shift sensing device 4 c monitors the center of gravity and mass shift areas 2 a and 9 v output signals are sent to the C/G system controller 4 b. The C/G shift controller will then send outputs to the attached suspension devices as determined by the riding condition parameters.

FIG. 22 is the side elevation view of human seated on bicycle back to the original position after encountering the obstruction 20 e. The C/G shift system controller 4 b receives signals from the C/G shift sensor 4 c regarding the mass shift 2 g is now in a backward direction. The C/G shift system controller 4 c sends a signal to one or multiple suspension devices 20 a, 20 b, 20 c, and 20 d introduced in FIG. 20 to compensate for the shift. The suspension devices are relaxed or stiffened to compensate for the mass shift 2 g force and direction.

In the initial control cycle the system is reset to zero (shown in block diagram 59A) then initial load measurements are taken (block 59B). The C/G position is determined by the inputs (block 59C) and the decision tree is then routed to the corresponding start blocks (blocks 59L, 59D, or 59T) for different C/G positions, Climbing, Downhill, and Sitting respectively. The routing for a C/G position described as Climbing is, as follows, if the cycle is the first cycle (block 59L) then the control system will look up the scanned history and make changes (or not) based on the new C/G position data (block 59L). The system will send a signal to regulate spring load until balanced with the load sensor data (block 590). The system will read load sensors (block 59P) to determine the energy absorption rate of the vehicle structure and adjust the damping rate to match conditions (block 59Q). The system will compute the last two scanned cycles to create a new baseline (block 59R) to use as comparison for the next cycle (block 59S) then return to the beginning of the cycle (block 59B). If the cycle was not the first cycle (block 59L), then the control system would look up the baseline value (block 59M) to determine if the energy absorption rate has changed (block 59M) and would regulate the spring load (block 590), or if the baseline value has not changed then the system would start the recomputed cycle (blocks 59R and 59S) and return to the beginning (block 59B). An analogous procedure is followed for the C/G Downhill position using system parameter data designed for the optimal operating load conditions for the position. The control system (block 59D) routes to a new scan process (block 59E) of regulating the spring load until balanced with sensors (block 59F) if the cycle is beginning a first pass then reading the load sensors on the vehicle structure (block 59G) and adjusting to comply with the energy absorption rate parameters (block 59H) set for the C/G downhill position. If the look up table at (block 59D) is not the first cycle then the control system will route to (block 59K) to determine if there has been a change in load. The control system then will route to the load adjusting path (blocks 59F, 59G, and 59H) or the re-scan path (blocks 59I and 59J) based on the yes/no data value (in block 59K). Another analogous procedure is followed for the C/G Sitting position using system parameter data designed for the optimal operating load conditions for the position. The control system (block 59T) routes to a new scan process (block 59V) of regulating the spring load until balanced with sensors (block 59W) if the cycle is beginning a first pass then reading the load sensors on the vehicle structure (block 59X) and adjusting to comply with the energy absorption rate parameters (block 59Y) set for the C/G downhill position. If the look up table at (block 59T) is not the first cycle then the control system will route to (block 59U) to determine if there has been a change in load. The control system then will route to the load adjusting path (blocks 59W, 59 x, and 59Y) or the re-scan path (blocks 59Z and 59AA) based on the yes/no data value (in block 59U).

The advantages of using the interactive human center of gravity and mass shift control system is that terrain is not required to be the initiator of the vehicle's dynamic systems. Thus, the invention is not concerned with where the contact points are, but is more concerned with actual center of gravity shifts and range of motion. Example: Rider could be in contact at three contact points to bicycle, and yet load is shifted from rear to front by merely leaning torso forward more. Contact points still the same, but C/G position and mass shift has occurred. Typical current inactive, semi-active, and active suspension systems will not sense this nuance.
While the invention has been described in relation to preferred embodiments of the invention, it will be appreciated that other embodiments, adaptations and modifications of the invention will be apparent to those skilled in the art.
