A method to control a steer-by-wire steering system of a road vehicle including a road wheel actuator to turn steerable road wheels and a steering wheel actuator to apply a feedback torque to a steering wheel, includes calculating the feedback torque by modifying a base steering torque as a function of a longitudinal and/or lateral acceleration measured by sensors of the vehicle, and sending the calculated feedback torque to the steering wheel actuator to provide feedback to the driver at the steering wheel.

Steer-by-wire steering system with acceleration dependent steering torque feedback

The vehicle steering control system includes a control unit configured to control the steering actuator to achieve the steered angle based on at least one of the steering angle and the steering torque. The control unit executes an output restriction control to restrict an output of the steering actuator when a steering torque is equal to or greater than a prescribed threshold value, and cancels the output restriction control when the detection unit has detected a prescribed mode of operation by the operator while the output restriction control is being executed.
