Abstract

In a vehicle combination consisting of a hauling truck (1) and a semitrailer (2), the brake system of the hauling truck (1) comprises a valve (8) which allows the brake pressure supplied to the brakes of the semitrailer (2) to be adapted to the brake pressure supplied to the brakes of the hauling truck (1). The adaptation is carried out by means of an electronic control unit (16) in which the actual deceleration of the vehicle combination during a braking sequence is compared with an anticipated deceleration. In the event of discrepancies between these decelerations, a control valve (23) is actuated, whereupon the valve (8) is supplied with a pneumatic signal which ensures that the semitrailer (2) is supplied with a higher or a lower brake pressure relative to the hauling vehicle (1), depending on whether the actual deceleration was lower or higher than the anticipated deceleration.
