STEERING CONTROL FOR THE REAR WHEELS OF A MOTOR VEHICLE AND AN ASYMMETRICAL ADHERENCE BRAKING SITUATION

摘要

The inventive method for controlling steering of rear wheels of a motor vehicle provided with at least four steerable wheels consists in detecting an asymmetrical adherence braking situation, in determining a first intermediate value (218) of the rear wheel steering angle instruction from the value (212) of the vehicle instantaneous longitudinal speed and the steering angle value (214) of the front wheels, in evaluating the perturbation (217) of the yaw speed (213) of the vehicle according to said preceding value (215) of the rear wheel steering angle instruction, in determining the second intermediate value (219) of the rear wheel steering angle instruction according to said perturbation, in determining the current value (220) of the rear wheel steering angle instruction by adjusting said first intermediate value (218) of the rear wheel steering angle instruction with the second intermediate value (219) of the rear wheel steering angle instruction and in transmitting said current value (220) of the rear wheel steering angle instruction to at least one steering actuator (120) of said rear wheels.
