Abstract:
1. In a method for brake pressure distribution between axles of a vehicle having a pressure medium brake, the vehicle including rotational speed sensors assigned to brakeable wheels and providing actual wheel speed signals, wherein the brake pressure distribution between axles is regulated as a function of a difference in wheel rotational speeds between axles or wheel slip values between axles at the axles and an exceeding of a predefined limit value by the difference serves for the brake pressure distribution regulation, the method comprising: determining a brake pressure at the rear axle and determining a deceleration of the vehicle at first and second service braking operations of the vehicle; interpolating or extrapolating based on a dependency between the brake pressure at the rear axle and the deceleration of the vehicle after at least the first and second service braking operations to acquire a critical deceleration value at which at least the brake pressure at the rear axle would become lower than a predefined brake pressure limiting value.
