ABSTRACT:
A power steering system incorporates a stability augmentation control program so as to provide hydrostatic power steering to the front and/or rear wheels of a vehicle. The hydrostatic steering system utilizes a control piston responsive to movement of a rack element of the rack and pinion steering connection of the vehicle steering system. A steering wheel angle sensor is connected to the steering shaft for providing an output angle signal to the steering controller and an electric motor of the system is responsive to a command signal generated by the steering controller. The steering of the wheels of the vehicle is then controlled in response to the steering wheel angle, vehicle speed and yaw rate of the vehicle. The controller receives inputs from each of the sensors so as to provide a control signal permitting stable steering control of the front wheels of the vehicle. The system is also applicable for providing steering for rear wheels of the vehicle in which a position sensor provides a control signal to the controller for controlling hydrostatic power to a control chamber for a steering rod of the rear wheels of the vehicle.
