The system comprises a controller (9) mountable in or on the towing vehicle, detector means (7)associated with the coupling means for detecting locking thereof, and pneumatic control means (15, 24) regulating the pneumatic brake supply to the trailer, the controller (9) being arranged to control operation of the pneumatic control means in response to the output of the detector means. The system is characterised in that the controller is also connected to a parking brake sensor (10) for sensing whether or not the parking brake of the towing vehicle has been applied, and is arranged to control operation of the pneumatic control means in response to the output of the detector means and the parking brake sensor.</p> |
