Abstract: Apparatus for controlling braking of a vehicle 1 includes an object proximity detection system for detecting an object in the path of the vehicle and an electronic braking system responsive to detection of an object within a predetermined distance of the vehicle by the object proximity detection system to apply the brakes to stop the vehicle. The object proximity detection system comprises one or more programmable radar heads 2a, 2b operable to provide a signal to a control unit 4 of the electronic braking system when an object id detected in the path of the vehicle. The radar heads 2a, 2b may be provided at the rear and/or front of the vehicle. The radar heads 2a, 2b are adjustable to alter the direction and range of the detection area covered by the radar heads 2a, 2b. The electronic braking system applies the brakes for a pre-determined period of time when an object is detected after which the brakes are released and the system re-set.
