Brake system and motor vehicle

A method for determining a switching state of a valve that is actuated by a coil, wherein the method includes: respectively ascertaining a current flowing through the coil and a voltage applied to the coil at several times which follow one another with a prespecified time interval, calculating an inductance variable of the coil based on the currents, the voltage and the time interval, and determining the switching state based on the inductance variable. Also disclosed is a solenoid valve assembly.

A pulsation damping capsule for connection to the pressure side of a piston pump having a metal membrane housing that is assembled from two membrane shells joined together in a hermetically sealed manner. The metal membrane housing separates an internal space from a surrounding pressure medium. The membrane shells are connected along a circumferential seam such that the pulsation damping capsule can compress and expand in a resilient-elastic manner as an energy convertor when subjected to external pressure as a result of pressure medium pulses. A reshapeable mass is arranged in the internal space and when the membrane shells are in the resilient-elastically compressed state, the mass completely fills an intermediate space that remains between the two membrane shells, so that the mass is precisely matched to the internal contour of the reshaped membrane shells while avoiding the formation of hollow spaces.

Pulsation dampening capsule

The invention relates to an hydraulic unit for a motor vehicle brake system which operates according to the feedback principle, for which purpose a low-pressure accumulator is provided between the outlet valves of the wheel brakes and a pump, and the piston of which low-pressure accumulator, in the basic position, disconnects the hydraulic connection between a pressure medium chamber and a connection leading to the pump such that, in the empty state of the low-pressure accumulator, the wheel brakes are reliably disconnected from the suction side of the pump.

Hydraulic unit

A hydraulic vehicle brake system including a brake line for conducting a hydraulic pressure medium and a master cylinder attached to a non-pressurized storage vessel. A wheel brake has a first pressure modulation valve on the inlet side and a second pressure modulation valve and a low-pressure accumulator on the outlet side of the wheel brake. A pump is disposed on a return line downstream of the low-pressure accumulator for removing pressurizing medium from the low-pressure accumulator to regulate the brake pressure via the first pressure modulation valve and also via an isolation valve disposed in the brake line upstream of the first pressure modulation valve. An electromagnetically opening changeover valve is inserted in a pump suction line discharging into the return line between the master cylinder and the low-pressure accumulator. The pressure provided by the master cylinder can be fed to the low-pressure accumulator, bypassing the wheel brake.

Hydraulic vehicle brake system

A brake system includes a main brake cylinder and a pedal decoupling unit provided with a holding piston, the first ring surface thereof together with a first primary brake cylinder piston defining a first hydraulic chamber that is hydraulically pressurized with an electrically controllable pressure supply device. In order to improve the pedal characteristics of the brake system, in particular in a brake-by-wire brake system, the holding piston is embodied as a differential piston, the second ring surface thereof defining a second, blockable hydraulic chamber, and a piston effect in the second chamber corresponds to a force that acts counter to the direction of actuation on the holding piston.

An externally actuable electrohydraulic vehicle brake system including an externally actuable electrohydraulic vehicle system with slip control. In order to make available a brake system which permits highly dynamic pressure build-up processes without throttling effects in the suction path, in particular through a master cylinder, being adversely affected, it is proposed that the hydraulic pump be assigned means which permit the hydraulic pump additionally to drive a hydraulic charging device which is connected to an inlet of the hydraulic pump.
