Means for electronic control of brake force distribution front / rear

Means for electronic control of brake force distribution front / rear in a vehicle brake system with pedalbetatigtem braking pressure generator with operating switch, with wheel cylinders (WCF, WCR), the brake circuit and disposed therein, electrically operated pressure control means (FV), as well as with wheel speed sensors (41-44), the signals are fed into an electronic control unit (10) and processed there to drive the pressure control means (FV) for controlling the brake force distribution, wherein said control electronics (10) - determines on the basis of the signal of the operation switch, whether a brake operation is present, - the speed difference between a front wheel and an associated rear wheel is calculated, - determines whether a rapid braking operation is present, wherein upon detection of rapid braking operation, a change of the entry criterion is carried out in the braking force distribution control in the sense that the braking force distribution control rather begins, than would be the case without the detection possibility for a rapid braking operation, characterized, in that a braking operation is detected as a rapid braking operation if the wheel speed of the front wheel exceeds the wheel speed of the rear wheel after previously within a predetermined time period (TS) to ...
