Embodiment Construction

[0029] figure 1 The shown regenerative braking system is intended for use in motor vehicles. This regenerative braking system mainly comprises a computer 2, a control device 3, a device 4 for determining the vehicle speed (longitudinal speed), an energy regenerative braking device 5 and, if necessary, detection of actions acting on the control parts of the dissipative braking device (function) of the device. The means for detecting actions acting on the control part of the dissipatively braking vehicle may comprise, for example, a contact detector on the control part of the dissipative braking device. Alternatively, the detection means may comprise a force sensor sensing the force exerted on the control part of the dissipative braking device, an action being considered to be acting on the control part when the force supplied by the sensor exceeds a force threshold. Still alternatively, the detection means may comprise a position sensor sensing the position of a control part ...

Abstract

The present invention relates to regenerative braking method for a motor vehicle, characterized in that the regenerative braking action is applied progressively, the rate of application of the braking action being dependent on the speed of the motor vehicle.

Description

technical field [0001] The invention relates to a regenerative braking method for a motor vehicle or an energy regenerative braking method for a motor vehicle. The invention also relates to a data medium comprising software means for carrying out such a method, a regenerative braking system intended for a motor vehicle and a vehicle comprising such a regenerative braking system. The invention also relates to a method of operating a regenerative braking system which makes it possible to carry out the regenerative braking method according to the invention. Background technique [0002] It is known that motor vehicles, especially electric or hybrid vehicles, are equipped with two braking systems: a first dissipative braking system and a second regenerative braking system. [0003] Dissipative braking systems convert the kinetic energy of a motor vehicle into dissipated energy, eg in the form of heat at the brake discs and / or drums. [0004] Regenerative braking systems conver...
