Abstract
A system for automatically and simultaneously controlling one or more vehicle functions by detecting the direction of movement of and the distance traveled by the vehicle. The control system includes an electronic sensor mounted on a selected one of the vehicle axles adjacent to and facing an anti-lock braking system tone ring of a selected one of the wheel hubs mounted on the axle. The sensor is electrically connected to an electronic control unit, which in turn is electrically connected to a vehicle function actuation device such as a lift axle solenoid or back-up alarm actuation device. The sensor transmits direction and distance information to the electronic control unit based on the movements of a plurality of teeth formed on the tone ring. The control system is a stand-alone system that is free of interfacing with other vehicle systems, such as the anti-lock braking system.
