Abstract
A braking system and method provided for a utility vehicle pneumatically coupled to a trailer. The system has an electronic control unit, a valve device that can be electrically connected by the at least one electronic control unit, the valve device building up pressure for the trailer braking system when connected, causing the trailer to brake, and a pressure sensor which detects the pressure for the trailer braking system and transmits a corresponding signal to the electronic control unit. The electronic control unit can influence the pressure generated for the trailer braking system by pulsed connection of the valve device, taking into account the pressure detected by the pressure sensor for the trailer braking system. The electronic control unit only allows the pulsed connection for braking the trailer when the service brake of the traction-vehicle is not activated, when conditions are such that the braking of the trailer could be useful in spite of a non-active service brake of the traction-vehicle, and when such an anti-jackknifing process is required by a signal generator.
