ABSTRACT:
An electric assist steering system comprises a steering torque sensor and an electric assist variable reluctance motor operatively connected to a steering member. A motor control signal is provided in response to a value of the torque signal for control of the assist motor. A motor speed sensor senses speed of the power assist motor and a vehicle speed sensor senses the vehicle speed. A control circuit modifies the motor control signal in response to the sensed motor speed and the sensed vehicle speed signal so as to provide damping that is functionally related to both the motor speed and the vehicle speed for vehicle yaw rate control.
