A power steering system includes a first steering device which controls the steering of the first wheels of the vehicle according to a first steering angle α1 and includes a first actuator capable of providing a steering assistance effort, a second steering device including a second actuator controlled by a controller as a function of a parameter related to the steering wheel movement, and controlling the steering of the second wheels, according to a second steering angle α2. In normal operation of the power steering system, α2 is set according to a first rule depending on the first steering angle α1. In case the steering wheel torque is greater than a predetermined threshold, the second steering device is operated in a forced mode by setting the second steering angle according to a rule depending on the first steering angle and taking into account at least one different or additional data, in order to cause an offset-oversteering of the second wheel. |
