摘要：A disable control system for a four-wheel steer vehicle disables rear-wheel steer capability when desired. The rear-wheel steer mechanism is responsive to, and at a fractional proportion of, the front wheel steering as a function of vehicle speed. The disable function operates in the dual, i.e. both front and rear steering mode only. The vehicle also includes a normal user selectable single steering mode, wherein only the front wheels are capable of being steered. Upon disablement of the rear wheel steering response, the control system automatically switches to the single steering mode, thus returning the rear wheels to a centered, zero steer angle, position.
