ABSTRACT:
An automatic braking system for a vehicle having a multichambered brake unit includes a control unit movement of the vehicle or obstacles behind the vehicle. This control unit is interconnected with a three-directional electromagnetic valve for controlling pressures within the various chambers of the brake unit. The system can prevent unwanted rearward movement of a vehicle when it is has been stopped on a slope or flat surface and is restarted. Further, obstacles behind the vehicle can be sensed when the vehicle is in reverse and a warning may be provided to the driver. If the vehicle continues to approach the obstacles, the braking system can stop the movement of the vehicle before an accident can occur.
