ABSTRACT:
A control apparatus for a power steering system comprises an electrically actuated flow control valve that varies the power assist available, a speed sensor for generating a signal indicative of vehicle speed, and a selector switch for selecting one of a plurality of power assist control options. The apparatus further includes a microprocessor that controls the electrically actuated flow control valve in response to the signal from the speed sensor and the setting of the selector switch. The apparatus also provides manually selectable power assist that is set by the operator and remains constant independent of variations in vehicle speed. A display provides a visual indication to the operator of the power assist available.
