摘要： A brake-pressure control device for a hydraulic multi-circuit brake system provides for brake-pressure generation, in addition to a brake unit, hydraulic regulating cylinders with electromotively drivable pistons. By electronic activation of the cylinders, the wheel brakes can be activated even without the cooperation of the driver. In the regulating cylinders of the front-wheel brakes, the pistons have a basic position, out of which brake-pressure build-up and reduction strokes can be executed. The pistons of the regulating cylinders of the rear-wheel brakes have a basic position which corresponds to the largest volume of the outlet-pressure spaces. The regulating cylinders are equipped with electronic position transmitters. A sensor whose output signal measures the expected value of the vehicle deceleration with which the driver wishes to brake is also provided. The brake-pressure build-up on the rear-wheel brakes takes place solely by the brake-pressure regulating members and on the front-wheel brakes both as a result of the actuation of the brake unit and as a result of the activation of the brake-pressure regulating members with the effect of a follow-up of the pistons into the position linked to the expected value of the vehicle deceleration.
