Abstract: 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.

Abstract: A device for supplying pressure to an actuation unit of a vehicle brake system, in particular to a vehicle brake system of the ‘brake-by-wire’ type, including a pneumatic motor-and-pump assembly with a pump and a motor driving the pump, wherein the motor-and-pump assembly is controlled by an electronic control unit depending on a pressure level or pressure difference in a pneumatic brake booster of the actuation unit, with the pressure level in a chamber or a difference in pressure between two chambers of the brake booster being detected by a sensor. In order to maintain the availability of the service brake function as high as possible and to obtain a maximum possible redundancy, the control unit, used to control the motor-and-pump assembly includes a logic module and a power module, which are arranged separately of each other.

Abstract: The present invention discloses an electronically controllable brake actuating system for automotive vehicles, including an unpressurized pressure fluid supply reservoir, a pressure source actuatable by an electronic control unit, the pressure of which can be applied to wheel brakes of the vehicle, further including a device for detecting the driver's wish for deceleration as well as valve assemblies inserted upstream of the wheel brakes and connecting the wheel brakes alternatively to the pressure source or the pressure fluid supply reservoir. In order to increase the operational or functional reliability of a system of this type, the present invention discloses the provision of means for detecting gases or air disposed in the system.

Abstract: 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.

Abstract: A method for controlling a brake system for automotive vehicles including a vehicle speed control unit permitting the adjustment of a predetermined vehicle speed by way of an automatic intervention into brake control, wherein upon a braking request of the vehicle speed control unit and, simultaneously, a braking request of the driver the function of the vehicle speed control unit is deactivated, wherein the pressure (Px) introduced into the wheel brake due to the braking request of the vehicle speed control unit is reduced according to a predetermined function upon the braking request of the driver, wherein preferably a resulting brake pressure (Pres) is adjusted in the wheel brake of the vehicle which is determined by the formula Pres=PF+PX[1]−(PF*PX[1])/constant Z.
