ABSTRACT:
A safety back-up system for a vehicle automatically applies the brakes to stop the vehicle against reverse movement when the vehicle begins moving backward without an attendant at the rear of the vehicle. The system senses reverse motion of the vehicle, whether rolling backward down an incline or driven backward by the engine and automatically applies the brakes, unless the automatic braking is disabled by application of a manual input by an attendant positioned near the rear of the vehicle with a handheld signal transmitter. A manual override device is available to the vehicle's driver, enabling the driver to override the automatic braking device from inside the vehicle when necessary. A record may be kept in a computer memory of all uses of the manual override, to assure that the system is not defeated. A driver seat switch may also be included, independent of the driver's override switch, for also applying the brakes if the driver leaves the seat while the vehicle is stationary, moving backward or moving slowly forward.
