AUTOMATIC CONTROL CIRCUIT FOR BRAKE CONTROL DEVICES ABSTRACT OF THE INVENTION An automatic control circuit for a brake con- trol device, relays around the device, light lamps and other parts to be operated differently under different circumstances, e.g., braking while running, braking to stop, releasing the brake pedal after braking, starting, parking after braking, and operation when the car s-tops is semi-automatic. The automatic control circuit oper- ates a valve in the hydraulic system which isolates the system after hydraulic pressure is increased, thus main- taining braking pressure even when the brake pedal is released. The valve isolates the hydraulic system until the clutch pedal is released and the accelerator pedal is depressed, then the valve is allowed to open and pressure is released. A vehicle movement detector is coupled to the circuit which ensures that brake pressure will not automatically be maintained when the vehicle is moving. The vehicle movement detector is also capa- ble of controlling a headlight relay so that current to the headlights is cut off when the vehicle is stationary, but current is allowed to pass to the headlights when the vehicle is in motion. The automatic control circuit is also capable of operating brake lights, pilot light and parking lamps.
