VEHICLE CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE A control system for a bi-directional shuttlecar having a loading end and a discharge end. A conveyor extends along the shuttlecar from the loading end to the discharge end, and a pressure sensing transducer is located at the loading end and an independent pressure sensing transducer is located at the discharge end. The pressure sensing transducers are connected in an electric circuit with programmable logic controller which also includes a drive motor for the conveyor and a controller for the drive motor. The weight of mined material supported on the conveyor at the loading end of the vehicle is sensed by the pressure sensing transducer at the loading end and creates a signal for transmission to the programmable logic controller to start the movement of the conveyor and the weight of the mined material at the discharge end of the vehicle is sensed by the pressure transducer at the discharge end and creates a signal for transmission to the programmable logic controller to stop the movement of the conveyor.
