Abstract (en)

[origin: WO2019076779A1] The method for commanding-controlling the orientation of the rear wheels of a four-wheel steering vehicle is executed from a step (100) of starting the vehicle to generate a steering-angle setpoint (αar ) for the rear wheels. The method comprises: - a step (102) of detecting that the temperature of at least one tyre is below a temperature threshold; - a step (103) of applying a first control law, triggered when the temperature is not detected as being below the temperature threshold, comprising a first limit on the amplitude of the said steering-angle setpoint (αar) for the rear wheels; - a step (104) of applying a second control law, triggered when the temperature is detected as being below the temperature threshold, comprising a second limit on the amplitude of the said steering-angle setpoint (αar) for the rear wheels which is lower, in terms of absolute value, than the said first limit within a first range of speeds (V1, V4) of travel of the vehicle.
