ABSTRACT:
A method is provided to determine an optimized value of the brake pressure ratio between a tractor and a trailer or semitrailer. In particular, an increased value of the brake pressure of the trailer or semitrailer in relation to the brake pressure resulting from the position of the brake pedal is supplied for a particular duration at the beginning of a braking operation. The increase of the brake pressure of the trailer or semitrailer takes place as a function of the brake pressure, p.sub.Anh, resulting from the position of the brake pedal. In braking operations when a tractor is travelling without a trailer or semitrailer, an allocation of the achieved deceleration, z.sub.ist, to the brake pressure p.sub.Zug of the tractor is stored as a function of the load state of the tractor. When the tractor is travelling with a trailer or semitrailer, a brake pressure is supplied for the trailer or semitrailer and is allocated to the brake pressure of the tractor such that, in subsequent braking operations, the actual value of the deceleration which is then set at a prevailing brake pressure of the tractor, giving due regard to the load state of the tractor, corresponds to the value, derived from the stored allocation, of the deceleration achieved without a trailer or semitrailer at the same brake pressure of the tractor.
