Abstract
With a view to controlling the distribution of brake force onto the front axle and the rear axle of a vehicle in dependence upon the static and dynamic axle load distribution as well as other sensed variables, sensors (2 to 4, 16 to 19) serve to ascertain the wheels' rotational behaviour at the front axle (VR) and at the rear axle (HR) as well as, if necessary, the translational deceleration of the vehicle, and, from this data, the brake slip ( lambda ) at the front and at the rear wheels or measured values that are proportional to the brake slip are determined. After the electronic combination and processing of these signals, the brake force distribution is controlled to provide brake slip at the rear wheels of 70 to 100% that of the front wheels by setting a ratio of actual braking force to dynamic axle load (fH) at the rear wheels to amount to from 80 to 100%, of that (fV) at the front wheels by modulation of braking pressure at the rear wheels. The rear braking pressure is increased in steps by successive signal pulses to the electrovalve 13 (Fig. 6) to provide front and rear brake pressure, PVR and PHR characteristics as in Figs. 3 and 4 for respectively a front disc/rear drum brake system and a system with similar front and rear brakes. <IMAGE>
