In a method for controlling a hydraulic braking system, wherein the braking system includes a hydraulic pump that is driven by an electric motor so as to generate a volume of fluid flow for the hydraulic braking system. the electric motor is controlled in such a manner that fluid pulsation in the hydraulic braking system is counteracted by means of modulating a rotational speed of the electric motor. The modulation is generated by means of the control procedure. Furthermore, a device is designed and configured so as to perform the method.

A motor vehicle brake system is specified. The brake system comprises a driving dynamics regulation system, which is designed to carry out a wheel-specific regulating intervention on each of a plurality of vehicle wheels, and an electrically controllable actuator, which is designed to generate or boost a service brake force. The brake system further comprises a control, which is designed, in the event of an identified loss of function of the driving dynamics regulation system, to select one of at least two vehicle wheels on which a regulating intervention by the driving dynamics regulation system would be required and to electrically control the actuator on the basis of a regulating intervention determined for the selected vehicle wheel.

A hydraulic braking system for a vehicle includes a master brake cylinder, a hydraulic unit and a plurality of wheel brakes, the hydraulic unit including at least one brake circuit for brake pressure modulation in the wheel brakes. A bistable solenoid valve is associated with at least one wheel brake, which valve is looped into the corresponding fluid channel, immediately upstream of the associated wheel brake, and in a de-energized open position enables brake pressure modulation in the associated wheel brake, and in a de-energized closed position seals a current brake pressure in the associated wheel brake, wherein a hydraulic force brought about by the sealed-in brake pressure acts in a seat-opening manner in the corresponding bistable solenoid valve.

A vehicle brake system and method for increasing the brake pressure in a first wheel brake cylinder and for limiting the brake pressure in a second wheel brake cylinder of a vehicle brake system. The method includes increasing a first brake pressure in the first wheel brake cylinder by controlling/holding a wheel inlet valve in its open state and controlling/holding a first wheel outlet valve in its closed state, and limiting an increase of a second brake pressure in the second wheel brake cylinder during the transfer of brake fluid into the first wheel brake cylinder by controlling/holding a second wheel inlet valve in its closed state and controlling a second wheel outlet valve into its open state.

In a solenoid valve for a hydraulic braking system, a valve body has a receiving region which at least partially accommodates a guide assembly, the valve armature running axially through at least one through-opening of the guide assembly. A mechanical detent device is formed between the guide assembly and the valve armature, the detent device releasing the valve armature when the latter is in a de-energised closed position, such that the restoring spring drives the valve armature and pushes the closing element sealingly into the valve seat to produce a sealing function, and said detent device fixes the valve armature in a de-energised open position against the force of the restoring spring in an axial detent position, such that the closing element is raised from the valve seat.

A method for operating a hydraulic brake system of a motor vehicle includes enabling a parking brake function by actuating a pressure generator and an actuator such that the pressure generator and the actuator together generate a total clamping force at a wheel brake, and actuating the pressure generator based on a movement of an actuator element and/or a brake piston, the movement generated by the actuator.

Furthermore, the method may be implemented in a corresponding device.

The pressure control valve for a vehicle includes: a valve body having an oil inlet part into which oil discharged from a wheel cylinder flows; a driving part installed in the valve body; a plunger connected to the driving part and movably installed inside the valve body; a valve seat disposed inside the valve body and having an oil passage part formed such that the oil flowing into the oil inlet part is supplied to an accumulator; a first elastic member installed to apply an elastic force to the plunger such that the plunger returns to an original position; an opening and closing member installed in the oil passage part to open the oil passage part when the opening and closing member is pressed by the plunger; and a second elastic member applying an elastic force to the opening and closing member such that the opening and closing member closes the oil passage part.
