Description
Technical field is more particularly to a kind of using vehicle inertia braking the present invention relates to a kind of brakes of vehicle
Method and its device.
Frictional force and air drag braking method of the existing vehicle braking method of background technology including passive type wheel,
Dynamic braking and regenerative braking.
The frictional force brakes of passive type are brake pedals, and master cylinder extrudes hydraulic oil, promotes wheelcylinder piston, makes system
Moving plate is rubbed on brake drum, and the braking effect of vehicle wheel rotation is stopped so as to reaching, and this braking has the disadvantage inertia energy quantitative change
Abandoned into frictional heat energy, and drawing brakes, sideslip, sideslip, whipping phenomenon easily occur.
Dynamic braking is then that motor is changed into generator to use, and the kinetic energy of vehicle is changed into electric energy, and dynamic braking is usual
Only the electricity for producing, change into useless heat by resistance and release, have the disadvantage to waste the energy.
Regenerative braking is then that electric power is stored, or is seen off by power network, recycled, equipment needed for this braking
It is many, technical sophistication, high cost.
Several brakings above are all the brakings in the opposite direction power without inertia, but directly to inertia braking, therefore
Brake force is small, and braking time is long.
The present invention is not to check that wheel is motionless, and inertia using vehicle in itself makes transmission system apply opposing torque,
And brake vehicle.
The content of the invention it is an object of the invention to provide a kind of energy that can make full use of vehicle inertia, and with actively
Cunning, sideslip, sideslip, the advantage of whipping phenomenon are not dragged in braking, and brake force is strong, and the time is short.
