A method for controlling a power steering system of a motor vehicle, the method including steps of: detecting an operating state of a steering actuator coupled to a rack; when the steering actuator is operational, providing a torque setpoint to a main motor of the steering actuator, by a first control unit of the steering actuator; when the steering actuator is faulty, but provides an angular position measurement of the main motor, controlling, by a second control unit, a brushless auxiliary motor, coupled to the rack, based on measuring the angular position of the main motor and an angular position of a steering wheel; and when the steering actuator has completely failed, controlling the auxiliary motor according to the angular position of the steering wheel.
