Abstract: An electrohydraulic vehicle brake system includes an electromechanical actuator for actuating at least one hydraulic piston to build hydraulic pressure at wheel brakes. The brake system provides a set of electrically activatable valve arrangements having a first valve arrangement between a cylinder accommodating the at least one hydraulic piston and each of the wheel brakes, and at least one second valve arrangement between a receptacle device for hydraulic fluid and at least one of the wheel brakes. The second valve arrangement is provided in parallel with the first valve arrangement which is associated with the same wheel brake as the second valve arrangement. A control device or system activates the first valve arrangements and the electromechanical actuator, in order to build up a hydraulic pressure at at least one of the wheel brakes and via the opened first valve arrangement associated with that wheel brake and to reduce a built-up hydraulic pressure via the opened first valve arrangement.

Abstract: An electro-hydraulic motor vehicle brake system is provided, having a first cylinder-piston device, which can be fluidically coupled to at least one wheel brake of the brake system, for generating hydraulic pressure on the at least one wheel brake, wherein the first cylinder-piston device comprises at least one first piston. The brake system further has a second cylinder-piston device, which comprises at least one second piston, and an electromechanical actuator which acts on the second piston of the second cylinder-piston device. The second cylinder-piston device is or can be fluidically coupled at the output side to the first piston of the first cylinder-piston device in order to provide a hydraulic pressure, which is generated in the second cylinder-piston device upon actuation of the electromechanical actuator, for actuating the at least one first piston of the first cylinder-piston device.
