ABSTRACT:
A power steering gear for a vehicle capable of providing a variable degree of power assistance to supplement manual steering effort wherein the variable assist is achieved by controlling directly the magnitude of the steering pressure made available to a pressure operated motor by a vehicle engine driven pump, the magnitude of the pressure being controlled by a central processing unit that responds to vehicle steering wheel torque and vehicle speed to produce an appropriate steering pressure and power assist for all driving conditions.
