摘要
An electric assist steering system (10) comprises a steering torque sensor (110) and an electric assist variable reluctance motor (26) operatively connected to a steering member (20). A motor control signal is provided in response to a value of the torque signal for control of the assist motor. A motor velocity sensor (200) senses velocity of the power assist motor and a vehicle speed sensor (119) senses the vehicle speed. A control circuit (220, 210, 142) modifies the motor control signal in response to the sensed motor velocity and the sensed vehicle speed signal so as to provide non-linear damping of the motor for vehicle yaw rate control.
