摘要:
A method of filling a pressure medium accumulator with a housing having an inner space that is subdivided into two chambers by a metallic pleated bellows used as a media-separating element. The first chamber thereof is filled with a gas and the second chamber is filled with a liquid pressure medium. The bottom valve is provided in a hydraulic port, its closing member being operable by the media-separating element. The valve permits filling of the second chamber with fluid and prevents a complete evacuation of the second chamber. To enable reliable filling of the above-mentioned chambers with corresponding media without damaging the pleated bellows, the method includes the steps of evacuating the second chamber, filling the second chamber with pressure medium and filling the first chamber with a gas.

A method for the operation of a brake system having two brake circuits, with a recuperative brake, in particular an electrical generator, a master brake cylinder and a brake pedal simultaneously achieve optimized use of the regenerative braking and a constant braking experience for the driver with the highest safety requirements. When there is a braking demand by the driver with an associated desired braking torque and a first condition is met, at least one outlet valve is opened and brake fluid is conducted with an associated volume of brake fluid into at least one reservoir and the at least one outlet valve is then closed if a second condition is met. The first condition is met if a braking variable corresponding to the braking demand is not less than a specified minimum value. The second condition is met if the volume of brake fluid has flowed into the reservoirs.

摘要:
Disclosed is a brake system of the ‘brake-by-wire’ type for actuating a motor vehicle brake system having a brake booster which is operable in response to the driver's input by a brake pedal and to an electronic regulating and control unit. A device is provided to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. The electronic regulating and control unit (7) includes a control circuit for controlling the travel (SDs) covered by the output member (20) of the brake booster (3), the nominal value (SDsnominal) of the travel (SDs) covered by the output member (20) of the brake booster (3) is calculated corresponding to the actuating travel (SBp) of the brake pedal (1), and a monitoring module (24) is provided which, in the case of a fault such as the inclusion of air or brake circuit failure, performs a partial compensation of the extension of the travel (SDs) covered by the output member (20) of the brake booster (3), which extension is caused by the fault.

摘要:
The present invention discloses a pressure fluid accumulator with a housing having its interior subdivided into two chambers by a media-separating element, the first chamber being filled with a gas and the second chamber being filled with a liquid, and wherein in a hydraulic port a bottom valve is provided whose closure member is operable by the media-separating element and which permits filling the second chamber with liquid and prevents complete evacuation of the second chamber. In order to prevent a damage of the bottom valve and an inadvertent escape of fluid and, thus, ensure a considerable increase in the reliability in operation, according to the present invention, the closure member can be moved by the media-separating element to adopt a position in which it fulfils the function of a hydraulic piston.
