    摘要: 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.

    摘要: A pressure-regulating solenoid valve (100) for a hydraulic circuit having at least one generator (300) of pressurized fluid, a pressure receiver (200) and a reservoir (400) of fluid under low pressure. The solenoid valve having an electric coil (10) which interacts with first (12) and second (14) pole pieces and a magnetic body (26). The magnetic body (26) moves under the effect of an actuating force (O) generated by a magnetic field created by the electric coil (10) and a distributor element (30) interacting with a sleeve structure (28) to command communication between a duct (66) connected to the pressure receiver and one of first (54) and second (42) ducts sequentially connected to the generator (300) of pressurized fluid or the reservoir (400) of fluid under low pressure. The solenoid valve (100) has at least one reaction chamber (46) which is permanently in communication with the pressure receiver (200) for receiving a reaction force which added to the actuation force (O) generated by the actuation of coil (10). The reaction force and actuation force are counter to a force (F) generated by an elastic means (34,36) which act on the movable magnetic body (26). The sleeve structure (28) is stationary with respect to the first and second pole pieces (12,14) while the distributor element (30) slides with respect to the sleeve structure (28) in response to movement of the magnetic body (26) responding to the reaction force and actuation force.

    摘要: A brake device for motor vehicles has at least two hydraulic brake circuits which are directly connected to a master brake cylinder, as well as an additional brake circuit, which is able to be actuated via a control device, independently of the master brake cylinder. Because of the separate hydraulic brake circuits in the region of the front axle, redundancy is provided, while the third brake circuit, that is able to be actuated independently of the master brake cylinder and typically acts on the rear wheels, during automatic actuation, permits taking into account a braking effect by additional active assemblies, such as a driven generator.
