摘要： A power steering system is disclosed herein that includes an electronic control unit that determines a set-point value for a damping moment in the power steering system. The system also includes a first sensor connected to the control unit and operable to determine a sign of a steering angle. The sign of the steering angle refers to a clockwise angle from dead center being designated as positive or negative and a counter-clockwise angle from dead center being assigned the other designation. The system also includes a second sensor connected to the control unit and operable to determine the sign of a steering wheel angular velocity. The sign of the steering wheel angular velocity refers to movement of the steering wheel in the clockwise direction being designated as positive or negative and movement in the counter-clockwise direction being assigned the other designation. The control unit can establish the set-point value for the damping moment with a predefined first damping multiplier when the steering angle and the steering wheel angular velocity have the same sign and with a predefined second damping multiplier when the steering angle and the steering wheel angular velocity have different signs.
