Abstract:
1. A power steering system for a motor vehicle, comprising: a torque sensor designed to measure torque applied by a driver to a steering wheel of the motor vehicle, a speed sensor designed to measure longitudinal speed of the motor vehicle, a steering motor designed to assist with manual force applied by the driver of the vehicle to the steering wheel, a processing unit designed to drive the motor, wherein the processing unit comprise determining electronic or software functions in one processor or in separate processors for determining a driving signal for driving the motor as a function: wherein the electronic or software functions for determining the driving signal that drives the steering motor limits the extent to which the second correction signal is taken into consideration so as to keep the driving signal within a defined interval about a value of the first control signal and wherein the second correction signal is determined as a function of a difference between the measurement of the torque applied by the driver to the steering wheel and the setpoint value determined as a function of at least one parameter characteristic of the lateral dynamics of the vehicle.
