Abstract
In a vehicle combination consisting of a haulage truck (1) and a semitrailer (2) the brake system of the haulage truck (1) comprises a control valve (8) which allows the brake pressure imparted to the brakes (4) of the semitrailer (2) to be adapted to the brake pressure imparted to the brakes (3) of the haulage truck (1). The adaptation is carried out with the use of an electrical control unit (16), in which the actual deceleration of the vehicle during a braking sequence is compared to an expected deceleration. In the event of a discrepancy between these, a control member (15) on the control valve (8) is actuated automatically so that the semitrailer (2) is supplied with a higher or lower brake pressure relative to the haulage vehicle (1) depending on whether the actual deceleration was lower or higher than the expected deceleration. As a result of the adaptation, the brakes of the haulage truck (1) and of the semitrailer (2) can be used better under various operating conditons.
