Redundancy hardware design philosophy for the control signal stage of a vehicle braking system in which all wheels are each connected to at least one rotating electrical machine

摘要

An electric braking system is provided for a road vehicle that includes at least one wheel connected for rotation to at least one rotary electric machine. At least one electronic wheel control module controls an electric machine of a corresponding wheel, The electric braking system includes: a central unit (3) for ensuring management of a vehicle displacement, the central unit controlling the at least one electronic wheel control module (23); a braking control available to a driver, the braking control being connected mechanically to at least: a first sensor (C1) outputting a vehicle braking control signal having a given amplitude representing a total braking force desired for the vehicle, and a second sensor (C2) outputting a vehicle braking control signal having a given amplitude representing the total braking force desired for the vehicle. The first sensor (C1) outputs its control signal to the central unit (3) and the second sensor (C2) outputs its control signal to one or each of the at least one electronic wheel control module (23).
