Abstract
System for electrical braking of a road vehicle of which at least one wheel is linked in rotation to at least one rotary electric machine, at least one wheel drive electronic module 23 driving the electric machine or machines of one and the same wheel, comprising a central unit 3 ensuring the management of the movement of the vehicle, the said central unit controlling the wheel drive electronic module or modules 23, comprising a braking control at the disposal of a driver, the said control being linked mechanically at least to three sensors C1, C2, C3 delivering a control signal for braking the vehicle having a given amplitude representative of the total braking force desired for the vehicle, the said sensors C1, C2, C3 being distributed into a first group C1 and a second group C2, C3, in which the sensor (sensors) C1 of the first group delivers (deliver) its (their) control signal to the said central unit 3 and the sensor (sensors) of the second group C2, C3 delivers (deliver) its (their) control signal to the or to each of the wheel drive electronic modules 23.
