Redundant hardware architecture for the control signals stage of system for braking a vehicle all of whose wheels are each linked to at least one rotary electric machine

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 moduledriving the electric machine or machines of one and the same wheel, comprising a central unitensuring the management of the movement of the vehicle, the said central unit controlling the wheel drive electronic module or modules, comprising a braking control at the disposal of a driver, the said control being linked mechanically at least to three sensors C, C, Cdelivering a control signal for braking the vehicle having a given amplitude representative of the total braking force desired for the vehicle, the said sensors C, C, Cbeing distributed into a first group Cand a second group C, C, in which the sensor (sensors) Cof the first group delivers (deliver) its (their) control signal to the said central unitand the sensor (sensors) of the second group C, Cdelivers (deliver) its (their) control signal to the or to each of the wheel drive electronic modules
