In the following, the invention will now be described by way of example, not limitation Kender embodiments explained in more detail.

It shows:

Figure 1 shows a first exemplary embodiment of the invention in cal matic, partially sectioned view. and

Fig. 2 shows a second exemplary embodiment of the invention in a schematic, partially sectioned view.

The Fig. 1 schematically shows a vehicle 1 with a drive unit 2, such as engine or internal combustion engine. Furthermore, a torque transmission system 3 and a transmission 4 are shown in the drive train of the vehicle. In this embodiment, the torque transmission system 3 is arranged in the power flow between the engine and the transmission, a drive torque of the engine being transmitted via the torque transmission system to the transmission and from the transmission 4 on the output side to an output shaft 5 and to an ordered axis 6 and to the wheels 6 a becomes.

The torque transmission system 3 is designed as a clutch, such as a friction clutch, multi-plate clutch, magnetic powder clutch or converter lockup clutch, the clutch being a self-adjusting, a wear-compensating clutch. The transmission 4 is shown as a manual transmission, such as a multi-speed transmission. According to the inventive idea of the invention, the transmission can also be an automated manual transmission, which can be switched automatically by means of at least one actuator. An automated manual transmission is further understood to be an automated transmission which is switched with a traction interruption and the switching operation of the transmission ratio is carried out in a controlled manner by means of at least one actuator.

An automatic transmission can also be used, an Au tomat transmission a transmission with essentially no interruption in tractive power the switching operations and usually through planetary gear stages is constructed.  

Furthermore, a continuously variable transmission, such as a cone pulley transmission, can be used. The automatic transmission can also be designed with a torque transmission system 3 arranged on the output side, such as a clutch or friction clutch. The torque transmission system can also be designed as a starting clutch and / or reversing clutch for reversing the direction of rotation and / or a safety clutch with a selectively controllable transferable torque. The torque transmission system can be a dry friction clutch or a wet friction clutch that runs in a fluid, for example. It can also be a torque converter.

The torque transmission system 3 has a drive side 7 and an output side 8 , wherein a torque is transmitted from the drive side 7 to the output side 8 by the clutch disc 3 a by means of the pressure plate 3 b, the plate spring 3 c and the release bearing 3 e and the flywheel 3 d is subjected to force. For this purpose, the release lever 20 is actuated by means of an actuating device, such as an actuator.

The torque transmission system 3 is controlled by means of a control unit 13 , such as a control unit; which can include the control electronics 13 a and the actuator 13 b. In another advantageous embodiment, the actuator and the control electronics can also be arranged in two different structural units, such as housings.

The control unit 13 can contain the control and power electronics for controlling the electric motor 12 of the actuator 13 b. As a result, it can advantageously be achieved, for example, that the system requires the construction space for the actuator with electronics as the only installation space. The actuator consists of a drive motor 12 , such as an electric motor, the electric motor 12 acting on a master cylinder 11 via a gear, such as a worm gear or spur gear or crank gear or threaded gear spindle drive. This effect on the master cylinder can take place directly or via a linkage.

The movement of the output part of the actuator, such as the master cylinder piston 11 a, is detected with a clutch travel sensor 14 , which detects the position or position or the speed or the acceleration of a variable which is proportional to the position or engagement position or the speed or acceleration of the clutch . The master cylinder 11 is connected via a pressure medium line 9 , such as a hydraulic line, to the slave cylinder 10 . The output element 10 a of the slave cylinder is operatively connected to the release lever or release means 20 , so that movement of the output part 10 a of the slave cylinder 10 causes the return means 20 to also be moved or tilted in order to control the torque that can be transmitted from the clutch 3 .

The actuator 13 b for controlling the transferable torque of the torque transmission system 3 can be actuatable by pressure medium, ie it can be equipped with a pressure medium transmitter and slave cylinder. The pressure medium can be, for example, a hydraulic fluid or a pneumatic medium. The actuation of the pressure transmitter cylinder can be seen by an electric motor, whereby the electric motor 12 can be controlled electronically. The drive element of the actuator 13 b can be in addition to an electromotive drive element's also another, for example pressure medium-actuated drive element. Magnetic actuators can also be used to adjust a position of an element.

In the case of a friction clutch, the transferable torque is controlled in that the contact pressure of the friction linings of the clutch disk between the flywheel 3 d and the pressure plate 3 b takes place in a targeted manner. About the position of the disengagement means 20 , such as release fork or central release, the force applied to the pressure plate or the friction linings can be controlled in a targeted manner, the pressure plate being moved between two end positions and being able to be set and fixed as desired. One end position corresponds to a fully engaged clutch position and the other end position corresponds to a fully disengaged clutch position. To control a transferable torque, which is, for example, less than the momentary engine torque, a position of the pressure plate 3 b can be controlled, for example, which lies in an intermediate region between the two end positions. The clutch can be fixed in this position by means of the targeted actuation of the disengaging means 20 . However, it is also possible to control transmissible clutch torques that are defi ned above the engine torques currently pending. In such a case, the currently occurring engine torques can be transmitted, the torque nonuniformities in the drive train being damped and / or isolated in the form of, for example, torque peaks.

For control, such as control or regulation, of the torque transfer system are still used, at least temporarily monitor the relevant variables of the entire system and those for control necessary state variables, signals and measured values that are supplied by the Control unit to be processed, one signal connection to another Electronic units, such as a motor electronics or Electronics of an anti-lock braking system (ABS) or an anti-slip control (ASR) can be provided and can exist. Detect the sensors for example speeds, such as wheel speeds, engine speeds, the position the load lever, the throttle valve position, the gear position of the transmission, an intention to shift and other vehicle-specific parameters.

Fig. 1 shows that a throttle valve sensor 15 , an engine speed sensor 16 , and a speedometer sensor 17 are used and transmit measured values or information to the control unit. The electronics unit, such as the computer unit, of the control unit 13 a processes the system input variables and forwards control signals to the actuator 13 b.

The transmission is designed as a step change transmission, the transmission stages being changed by means of a shift lever or the transmission being operated or operated by means of this shift lever. Furthermore, at least one sensor 19 b is arranged on the operating lever, such as shift lever 18 , of the manual transmission, which detects the intention to shift and / or the gear position and forwards it to the control unit. The sensor 19 a is articulated on the transmission and detects the current gear position and / or a shift view. The switching intention detection using at least one of the two sensors 19 a, 19 b can take place in that the sensor is a force sensor which detects the force acting on the shift lever. Furthermore, the sensor can also be designed as a displacement or position sensor, the control unit recognizing an intention to switch from the temporal change in the position signal.

The control unit is at least temporarily in signal connection with all sensors and evaluates the sensor signals and system input variables in such a way that, depending on the current operating point, the control unit issues control or regulation commands to the at least one actuator. The drive element 12 of the actuator, such as an electric motor, receives from the control unit, which controls the clutch actuation, a manipulated variable as a function of measured values and / or system input variables and / or signals from the connected sensors. For this purpose, a control program is implemented in the control unit as hardware and / or software, which evaluates the incoming signals and calculates or determines the output variables on the basis of comparisons and / or functions and / or characteristic maps.

The control unit 13 has advantageously implemented a torque determination unit, a gear position determination unit, a slip determination unit and / or an operating state determination unit or is in signal connection with at least one of these units. These units can be implemented by control programs as hardware and / or software, so that by means of the incoming sensor signals the torque of the drive unit 2 of the vehicle 1 , the gear position of the transmission 4 and the slip which prevails in the area of the torque transmission system and the current operating state of the vehicle can be determined. The gear position determination unit determines the currently engaged gear on the basis of the signals from the sensors 19 a and 19 b. The sensors are articulated on the shift lever and / or on internal gear means, such as a central shift shaft or shift rod, and detect them, for example the position and / or the speed of these components. Furthermore, a load lever sensor 31 can be arranged on the load lever 30 , such as gas pedal, which detects the load lever position. Another sensor 32 can act as an idle switch, ie when the accelerator pedal, such as a load lever, this idle switch 32 is switched on and when a signal is not actuated, it is switched off, so that digital information can be used to detect whether the load lever, such as the accelerator pedal, is actuated becomes. The load lever sensor 31 detects the degree of actuation of the load lever.

An energy accumulator, such as plate spring 102 f, acts on the pressure plate in the axial direction towards the clutch disc, a release bearing 109 , such as, for example, pressure-actuated central release mechanism, being provided for actuating the torque transmission system. A release bearing 110 is arranged between the central releaser and the tongue spring tongues of the plate spring 102 f. Axial displacement of the release bearing causes the disc spring to act and disengages the clutch. The clutch can also be designed as a pressed or a pulled clutch.

The actuator 108 is an actuator of an automated manual transmission, which also contains the actuation unit for the torque transmission system. The actuator 108 actuates internal shift elements, such as, for example, a shift drum or shift rods or a central shift shaft of the transmission, whereby the gears can be engaged or removed in, for example, sequential order or in any order.

The control unit of the automati-based clutch actuation 13 controls the transferable torque of the torque transmission system according to predefinable functions or maps, so that a steady state of equilibrium is established between the actuated engine torque and the clutch torque. The equilibrium state is characterized as a function of the load lever position a by a defined starting speed, a starting or engine torque as well as a defined transferable torque of the torque transmission system and a torque transmitted to the drive wheels, such as drive torque. The functional relationship of the starting torque as a function of the starting speed is never referred to as starting characteristic in the following. The load lever position a is proportional to the position of the throttle valve of the engine.
