    Abstract: In a method for carrying out an automatic braking in a motor vehicle with the aid of a pump which delivers a brake fluid in the direction of the wheel brakes, the brake pressure prevailing in the brake circuit is limited by a valve, which is overflowed when a settable pressure threshold is reached, and thus limiting the brake pressure. The dynamics of the pressure build-up is improved if the valve opens only at higher pressures, since a greater share of the volume flow coming from the hydraulic pump is then in fact conducted to the wheel brakes and is not able to flow off prematurely via the valve.

    Abstract: A device for controlling the brake pressure in a hydraulic brake system with the aid of a pressure-limiting valve that limits the brake pressure to a predefined threshold value, and to that end is driven by an electronic device in accordance with a valve characteristic curve. The setting accuracy can be improved considerably if an estimating unit for estimating the brake pressure, a sensor system for measuring the brake pressure, a unit for determining a pressure difference between the measured brake pressure and the estimated brake pressure, as well as a controller unit which drives the pressure-limiting valve as a function of the pressure difference are provided.

    Abstract: The invention relates to a method for operating a braking system for motor vehicles with electrically actuated hydraulic valves, the coils of which are powered up, at least in phases, with currents which modify the currentless state of the hydraulic valves, in order to heat the hydraulic fluid present in the system. The hydraulic fluid is heated via a heating profile which, in accordance with the hydraulic fluid temperature, activates the heating phase of the hydraulic fluid. The heating profile consists of a first heating phase and, subsequent thereto, a second heating phase. During the first heating phase, the coils are powered up in such a way that the coil temperature at the end of the first heating phase corresponds to a pre-defined temperature value of the coil which is at least approximately maintained during the second heating phase when powering up the coils.

    Abstract: In a method for controlling a selector valve situated in a hydraulic brake system of a motor vehicle, the selector valve is opened by applying an electrical signal having various control phases having different current intensities. The thermal load and the noise of the valve are significantly improved if the lengths of the control phases for the pilot stage or the holding phases are variably adapted to the driving situation.
