Abstract: A method is provided for operating a motor vehicle brake system that includes an actuatable brake master cylinder, a hydraulic brake booster, and at least one brake circuit that has at least one hydraulically actuatable wheel brake and at least one hydraulic-pressure generator driven by electric motor. The method includes monitoring a state of actuation of the brake master cylinder is monitored, and, upon detecting a maximum state of actuation, activating the hydraulic-pressure generator to increase the hydraulic pressure adjusted by the brake master cylinder in the brake circuit.

Abstract: A method for braking a motor vehicle in critical driving situations in which the risk exists that the transverse forces acting on the vehicle will become so great in the continued progression of its movement that it rolls over laterally. In order to reduce the risk of a lateral rollover, the vehicle operation is monitored with regard to such critical driving situations and a parking brake is activated automatically if a critical driving situation is detected.

Abstract: A method for braking a vehicle in a driving situation, in which an automatic braking function is active. The hydraulic pump of the brake control system may be sized to be relatively small and cost-effective, if, in critical driving situations, an additional braking device is automatically switched on or its braking capacity is increased, in order to assist the service brake and further decelerate the vehicle.

Abstract: A brake device is described for braking the wheels of a vehicle. The brake device includes at least one brake master cylinder, a brake booster, a wheel brake, a return pump, using which a hydraulic fluid may be pumped back from the wheel brake in the direction of brake master cylinder. A sensor system for detecting an abrupt negative change in the friction coefficient of the roadway is provided. An arrangement is provided according to which the boost of the brake booster is set to a smaller value if a braking maneuver has been detected on a roadway having an abrupt negative change in the friction coefficient than in the case of a braking maneuver on a roadway without an abrupt negative change in the friction coefficient.

Abstract: A method for improving the driving stability of a vehicle, including ascertaining a trajectory to be followed by the vehicle in a situation-specific manner, an active steering system and/or a braking device being set in the vehicle in such a way that at least one transverse dynamic state variable is within an associated limiting value.

Abstract: A vehicle hydraulic brake system with wheel slip control includes two brake circuits and brake pressurization valves and brake pressure-reduction valves for each wheel brake. The two brake circuits are connected by a connecting valve in the form of a non-return valve on a side of the wheel brakes remote from the brake pressure valves. The connecting valve permits a more rapid build-up of the wheel brake pressure in the wheel brakes of the one brake circuit when a brake pressure in the other brake circuit is lower.

Abstract: In a method for operating an hydraulic brake system in a vehicle, which has at least two electrically actuable hydraulic valves, the hydraulic valves are energized at a different current intensity at least intermittently in order to heat the hydraulic fluid during a heating period.

Abstract: A method and a device for the open- and/or closed-loop control of a generator or a dynamo in a vehicle. The generator supplies, at least part of the time, an electric motor located in a braking system, e.g., a pump motor, with electrical power. A main feature is that the generator is activated as a function of the pressure in the brake master cylinder, it being activated as soon as the pressure in the brake master cylinder exceeds an initial threshold value.

Abstract: A magnet valve, including a pole core, an armature, a restoring element disposed between the pole core and the armature to restore the armature to its outset position a stop face on the pole core oriented toward the armature having at least one rib extending all the way around in the circumferential direction and protruding toward the armature, and/or a stop face of the armature oriented toward the pole core and having at least one rib extending all the way around in the circumferential direction and protruding toward the pole core.

Abstract: A hydraulic part of a magnet valve is received in a bore of a valve block. The hydraulic part is secured to the valve block with a calked heel of a securing bush that is slipped onto a guide sleeve of the hydraulic part. The securing bush rests on an annular shoulder of the guide sleeve and engages a jacket wall of the guide sleeve with a press fit, and one edge of the securing bush is adapted to a rounded-out throat between the jacket wall and an end wall of the annular shoulder by means of plastic deformation. A valve sleeve engages a portion of the bore of the valve block with a press fit. The calked heel, the plastically deformed edge of the securing bush, and the press fit of the valve bush seals that seal off against fluid are achieved without using additional rubber-elastic sealing means.

Abstract: A hydraulic part 13 of a magnet valve 10 is received in a bore 14 of a valve block 11. The securing of the hydraulic part 13 to the valve block 11 is attained with a calked heel 53 of a securing bush 43 that is slipped onto a guide sleeve 21 of the hydraulic part 13. The securing bush 43 resting on an annular shoulder 27 of the guide sleeve 21 engages a jacket wall 28 of the guide sleeve 21 with a press fit. In addition, one edge of the securing bush 43 is adapted to a rounded-out throat between the jacket wall 28 and an end wall 29 of the annular shoulder 27 by means of plastic deformation. In addition, a valve sleeve 33 engages a portion 47 of the bore 14 of the valve block 11 with a press fit.
