Vehicle brake actuator (12) serving to automatically control the brakes (11) so that the brakes are operated at a predetermined rate and pressure in a number of indications in which it is desired to automatically brake the vehicle, such as a fault indication (103) from the engine, an indication from a vehicle mounted radar proximity circuit (104) indicating an impending collision, a theft alarm indicator (105), leaving the seat of the vehicle (31), a sobriety control indication (101) for a driver who lacks sobriety, a keypad indicator (34) into which a preselected number must be entered before operating the vehicle, a hood latch monitor circuit (107), a tachometer response circuit (108) that brakes the vehicle if the speed goes below a certain limit, and a miscellaneous circuit (114) that combines a number of indications for braking the vehicle. The brake actuator is operated by means of vacuum, hydraulic pressure or electric power and may include a canister for storing additional vacuum. The system may also include a seat switch delay circuit (101) which prevents unwanted braking if the driver passes a bump in the road. The brake actuator is automatically released the moment the driver operates the gas pedal. |
