  • Method and device for managing a turning setpoint applied to at least one turning actuator for the rear wheels of an automobile
    Patent number: 8712645
    Abstract: A method for managing a turning setpoint applied to at least one turning actuator for rear wheels of an automobile including four steering wheels, the turning setpoint being generated by a turning control unit upon a braking situation with asymmetrical adhesion. The method calculates an intermediate turning setpoint of the rear wheels for compensating a yaw torque generated by a braking with asymmetrical adhesion of the four wheels, transmits an intermediate turning setpoint to the at least one turning actuator for the rear wheels, monitors the value of the intermediate turning setpoint using an acceptation module, and transmits to a braking control unit information generated by the acceptation module of the intermediate turning setpoint.

  • Device for orientating rear wheels
    Patent number: 8100219
    Abstract: A device for orientating rear wheels of a vehicle, including: a rear axle fitted with two orientable wheels; an actuator including: a body with a lubricated guide bearing and an actuating member that can move relative to the body, guided by the bearing, and the movements of which orientate the wheels about the vertical of the rear axle; a temperature sensor; and a control circuit for the actuator, configured to lock movements of the actuating member when the temperature determined by the temperature sensor is below a predetermined threshold value.
