Abstract
A method decelerates a vehicle combination of a tractor vehicle and a trailer vehicle that has a trailer braking system. A brake control unit of a tractor vehicle braking system monitors the braking behavior of the tractor vehicle or vehicle combination and adjusts the brake pressure at the wheel brakes of the corresponding wheels of the tractor vehicle and a trailer brake pressure. The brake control unit detects a driver deceleration request to a retarder system and, during activation of the retarder system, monitors whether a predefined safety criterion is met, on the basis of a continually determined braking state variable. After a request to the retarder system by the driver, the stability of the vehicle combination is ensured in that, when the safety criterion is met, a portion of the deceleration request to the retarder system yet to be effectuated is effectuated by the trailer braking system.
