Abstract
Methods for controlling a feedback torque actuator and at least one yaw and/or lateral vehicle state actuator in a steer-by-wire steering system include measuring an input signal with a sensor, determining from the input signal a measure of a torque applied by the driver via a steering wheel, transforming the measure to a desired yaw and/or lateral vehicle state, controlling the yaw and/or lateral vehicle state actuator for vehicle state control, and defining a steering-wheel torque to steering-wheel angle relation describing steering feel. If the vehicle position control results in a yaw and/or lateral vehicle state error, this error is transformed to a change in the steering-wheel torque to steering-wheel angle relation describing steering feel. This new steering feel relation is used as an input signal for controlling the feedback torque actuator in order for the driver to get feedback of the yaw and/or lateral vehicle state error.
