A power steering system including a steering wheel, a return function to automatically return the steering wheel to a given reference position, and includes a function for calculating a return-speed setpoint which calculates a steering wheel speed setpoint from the steering wheel position error differentiating between the effective instantaneous position of the steering wheel and the reference position, then a function for calculating the return assistance, defining from the steering wheel speed error which is the difference between the effective speed of the steering wheel and the steering wheel speed setpoint, a return assistance setpoint, the system including a dynamic saturation function defining at least one saturation threshold, that the dynamic saturation function sets according to the value of the steering wheel speed setpoint, and the dynamic saturation function applies to clip the peaks of the return assistance setpoint calculation to confine the return assistance setpoint to an authorized domain.
