Abstract
A braking system is provided for a commercial vehicle that can be pneumatically coupled to a trailer. The system includes at least one electronic control unit, and a valve device that can be electrically connected by the at least one electronic control unit. The at least one valve device builds up pressure for the trailer braking system when connected, causing the trailer to brake. A throttle is arranged in a trailer control line. The throttle limits a pressure drop at the control inlet of a relay valve in the event of a leakage downstream of the throttle. A method for controlling a brake system is also provided.
