Abstract:
A control system for use with a braking system for a towed vehicle, comprising:(a) a hydraulic pressure generator including an electric motor driven pump for producing a hydraulic pressure that is directly proportional to an electrical power input to the electric motor, the hydraulic pressure generator being connected to the braking system in the towed vehicle; (b) a valve assembly fluidly connected to the hydraulic pressure generator and the braking system in the towed vehicle, the valve assembly having a pressure relief valve, an unloading valve and a check valve; and (c) a controller connected to the hydraulic pressure generator for controlling the electrical power input to the electric motor of the hydraulic pressure generator and the controller having an operator-selected input for setting a time duration of the electrical power input; the controller and the valve assembly selected to create a braking force in the towed vehicle proportional to the electrical power input to the hydraulic pressure generator.
