Abstract
The invention relates to a method and a device for controlling the operating brake pressure to pressure medium brakes in a vehicle combination comprising a tractor vehicle and at least one trailer vehicle. The vehicles in this case are connected by a conventional coupling device that includes standard brakeline connections. Forces developing in the coupling device are measured during the course of braking and are reduced to a predetermined value by adjusting the brake pressure for at least the brakes of the trailer vehicle in dependence on the longitudinal inclination of the tractor vehicle and of the actual deceleration thereof. The adjusted value of the brake pressure is retained for the purpose of being the starting value at the next braking of the vehicles.
