A hydraulics assembly, in particular for controlling the brake pressure of a wheel brake of an electronically slip-controllable brake system of a motor vehicle, includes a hydraulic block having a recess for receiving a pump element, a line connection for contacting the hydraulics assembly to the wheel brake, channels for providing the pump element with brake fluid, and a hydraulic cavity formed in the interior of the hydraulic block, which cavity is contacted with the recess for the pump element. The cavity includes a riser, which extends from the recess for the pump element in the direction toward the line connection of the hydraulic block and is contacted with the recess for the pump element. The suction line collects gas escaping from the pressure means due to temperature and/or pressure changes and improves the operating noise of the hydraulics assembly.

Hydraulics assembly, in particular for controlling the brake pressure of a wheel brake of an electronically slip-controllable brake system of a motor vehicle

A method for controlling a valve for maintaining brake pressure in a specified region of a brake circuit in a motor vehicle, in which the valve is controlled using a first control method, the specified region of the brake circuit is monitored with respect to the occurrence of a loss of brake pressure, and in response to a detected loss of brake pressure, the valve is controlled using a second control method.

Method and device for carrying out a stationary holding function on a motor vehicle

To achieve a specifiable, and thus reproducible final pressure in at least one part of the brake circuit, the pump is first actuated for pressure buildup or pressure reduction when the valve is closed. When a first specified setpoint pressure is reached, or when a pressure threshold value is exceeded, the valve is put into an open position using a first actuation. After the pump is switched off, the actuation of the valve is modified in such a way that, during a specifiable time, a continuous change of the first actuation is undertaken all the way up to a second actuation, in which the valve assumes a holding position, particularly while taking into consideration the pressure difference which prevails at the valve.
