  • Patent number: 8634990
    Abstract: 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.

  • Patent number: 8449048
    Abstract: An electric braking system is provided for a road vehicle that includes at least two wheels (1) each connected for rotation to at least one rotary electric machine (2), and one electronic wheel control module (23) controlling an electric machine of a corresponding wheel, with each electronic control module enabling a control torque of determined amplitude and sign to be imparted selectively to a corresponding wheel. The electric braking system includes at least two sub-systems (A and B) each including: at least one of the electronic wheel control modules (23), a central electric line (40), and a low-voltage electrical supply stage for supplying electronics for controlling and driving power elements. The low-voltage electrical supply stage includes a first low-voltage electrical supply and at least one second low-voltage electrical supply.

  • Patent number: 8449049
    Abstract: An electric braking system for a vehicle includes first and second sub-systems connected to each other by an electric line. The first sub-system, which includes a first dissipation device, controls braking in a first wheel set. The second sub-system, which includes a second dissipation device, controls braking in a second wheel set different from the first wheel set. The electric line is arranged such that: if the first dissipation device becomes inoperative, electrical power produced by the first sub-system is channeled towards the second dissipation device, and if the second dissipation device becomes inoperative, electrical power produced by the second sub-system is channeled towards the first dissipation device.

  • Patent number: 8246120
    Abstract: A fully electrically controlled electric braking system is provided for a road vehicle fitted with wheels (1). Each of the wheels is connected for rotation to at least one rotary electric machine (2) specific thereto, with at least one electronic wheel control module (23) controlling the electric machine(s) (2) of that wheel. Each electronic wheel control module (23) makes it possible to impart selectively to a corresponding wheel a control torque of determined amplitude and sign, in such a way that the corresponding wheel imparts to the vehicle a drive force or a braking force in accordance with the control torque. The system includes a central unit (3) for managing vehicle displacement, the central unit (3) controlling all the electronic wheel control modules (23). The central unit (3) has a vehicle braking mode activated by a vehicle braking control signal having a given amplitude representing a total desired braking force for the fully electrically controlled wheels.
