ABSTRACT:
A system is shown for automatically applying the brakes of a vehicle moving in reverse, when there is an obstruction in the path of the vehicle. Obstructions are detected by an ultrasonic sensing device which operates a valve, which causes the brakes to be applied. In one embodiment for use with hydraulic brakes, a dual accumulator utilizes both power-steering fluid and braking fluid in the operation of the system, without mixing the two fluids. In another embodiment, the system is used with a pneumatic braking system. In both embodiments, the system is activated only when the vehicle is in reverse gear. In still another embodiment, for use with hydraulic brakes, the brakes are applied solely by pressure from the power steering system of the vehicle.
