Abstract
A brake pressure regulation method and system for a trailer vehicle, which is connected to a tractor vehicle having an electronically controlled pressure-medium brake renders sensing of the forces between the tractor and the trailer vehicle and, to this extent, also a corresponding force-recording apparatus superfluous. The method can be used advantageously in tractor vehicles equipped with an ABS. The method is based on transmission of wheel speed signals from the trailer vehicle to the tractor vehicle and brings about an adjustment of the brake pressure relation between the tractor and the trailer vehicle to the same average speed of the wheels of non-driven axles of the vehicle by correcting the brake pressure for the trailer vehicle adaptively to give braking work which can be distributed in optimum fashion to the tractor vehicle and the trailer vehicle. Since, in this way, the average utilization of adhesion at braked wheels of the trailer vehicle is the same as that at the non-driven, braked wheels of the tractor vehicle, not only is an increase in directional stability during braking achieved but also an advantageous evenness of the brake lining wear on the tractor vehicle and the trailer vehicle. The method can also be carried out very advantageously in conjunction with electronically controlled pressure-medium ABS brake systems for trailer vehicles.
