Abstract
A vehicle steering apparatus (20) includes a steering feel motor (50). A torque sensor (58) senses steering torque applied by a vehicle driver. A sensor (24) senses a characteristic of a driver and provides a signal indicative thereof. A hazard sensor (44) senses a potential steering hazard. The steering feel motor is controlled in response to the sensed driver characteristic and to any sensed potential steering hazard. Either open-loop or closed-loop control is provided for controlling the feel motor in response to sensed static and dynamic forces.
