Abstract of the Disclosure Disclosed is a vehicle power steering system including an electro-hydraulic safety backup system for supplying pressurized fluid to the steering motor of the vehicle when the pressure be- tween the main pump and the power steering system drops below a predetermined pressure level. The safety backup system includes an electrical circuit which is added on to the ignition and start- ing circuits of a vehicle such that the backup system will not operate in response to intermittent short duration pressure drops, The electrical circuit includes an arming feature to prevent the backup system from operating during initial start-up of the ve- hicle and further provides for operation of the vehicle's start- ing motor to have priority over the backup system operation.
