Patent ID: 7416263

Claim:
A device for controlling the brake system of a vehicle, comprising: at least two separate hydraulic brake circuits, each brake circuit including: a switchover valve, which is in a blocking setting when there is a braking intervention not actuated by the driver; a return pump; a high pressure switching valve, which is in a pass-through setting if a braking intervention is to be carried out in the brake circuit by activation of the return pump; a pair of inlet valves for a corresponding pair of wheel brakes; and a pair of discharge valves for a corresponding pair of wheel brakes; and a wheel slip control system for initiating a buildup of first braking moments at least one wheel brake upon fulfillment of selected conditions, and initiating preparatory measures for a buildup of second braking moments in wheel brakes of remaining wheels in reaction to the buildup of the first braking moments, wherein the preparatory measures lead to substantially no braking action in the wheel brakes of the remaining wheels, and wherein the preparatory measures for the buildup of the second braking moments include, in each of the two brake circuits: putting the return pump into operation, if the return pump is not already in operation; putting the inlet valves into a pass-through setting, if the inlet valves are not already in the pass-through setting; putting the discharge valves of the wheel brakes into a blocking setting, if the discharge valves are not already in the blocking setting; putting the switchover valve into the pass-through setting, if the switchover valve is not already in the pass-through setting; and putting the high pressure switching valve into the pass-through setting, if the high pressure switching valve is not already in the pass-through setting, wherein, as a result of the preparatory measures for the buildup of the second braking moments, the remaining wheel brake cylinders are prefilled.
