Abstract: An electronic control device for a pressure controller, by way of which solenoid valves for pressure control are actuated with current via an actuating electronic system, and having a pump assembly is actuated as a function of a pressure request, which generates a volumetric flow with a periodically fluctuating amplitude. The wheel brake circuit isolating valve, during an active pressure build-up, discharging part of the delivery volume into a reservoir volume, at least in the case of a control operation which performs an intervention for driving stability which is not critical to safety, if the pressure which is built up by the assembly is higher than the pressure which is to be set, the electric coil current for the actuation of the isolating valve is modulated and the periodic actuation being interrupted at least when the control device has to carry out an intervention for driving stability which is critical to safety.

Abstract: An actuation unit for an electromechanically actuated disk brake for motor vehicles, arranged on a brake caliper (50) in which two brake linings (4, 5) interacting with lateral faces of a brake disk (6) are displaceable, one of the brake linings (4) being engageable by the actuation unit directly with the brake disk (6) by means of an actuating element (7). The actuation unit including an electric motor (1) and a reduction gear (2) operatively arranged between the electric motor (1) and the actuating element (7) and having a threaded spindle (17) which is driveable by the electric motor (1) and bears axially against the brake caliper (50). A rolling element bearing (33, 42, 63) and a force measuring device (30, 40, 60) having a deformable element (35, 43, 65) which is deformed when subjected to the force to be determined are arranged in the force flow between the threaded spindle (17) and the brake caliper (50).

Abstract: A brake system for motor vehicles, which brake system can be actuated both by the vehicle driver and also independently of the vehicle driver in a “brake by wire” operating mode, is preferentially operated in the “brake by wire” operating mode, and can be operated in at least one fall-back operating mode in which only operation by the vehicle driver is possible. The brake system has inter alia an electrohydraulic pressure generating device (5) which outputs a brake system pressure, and a pressure modulation unit which has one inlet valve (6a-6d) and one outlet valve (7a-7d) per wheel brake (8, 9, 10, 11) for setting wheel-specific brake pressures derived from the brake system pressure, wherein the inlet and outlet valves (6a-6d, 7a-7d) output or transmit the brake system pressure when in the non-actuated state.

Abstract: The invention relates to an electronic braking system (50) for motor vehicles (60), having at least one wheel brake (7, 8, 9, 10) actuated by an electromechanical actuator (11, 12), wherein the electromechanical actuator (11, 12) is associated with an electronic control and/or regulating unit (WCU) (18, 19, 20) in which a data processing program for controling and/or regulating the electromechanical actuator (11, 12) is executed. The system further having a data bus, in particular a CAN data bus, associated with the electronic control and/or regulating unit (ECU) (18, 19, 20). In the braking system a temporal coordination is achieved between an electronic control and regulating unit (18, 19, 20) assoicated with an electromechanical actuator (11, 12) and an additional control and regulating unit of the braking system. This this end, the loop time of the data processing program for controlling and/or regulating the electromechanical actuator (11, 12) may be altered via the data bus.

Each of the at least two linear sub-controllers (CL, CH; CLL, CLH, CHL, CHH) determines a function of a control deviation (e) of at least one wheel specific characteristic, a control variable suggestion (uL, uH; uLL, uLH, uHL, uHH) that includes a control variable suggestion for the wheel brake and a control variable suggestion for the drive engine, and an output control variable (u) including an output control variable for the wheel brake and an output control variable for the drive engine, is determined from the control variable suggestions (uL, uH; uLL, uLH, uHL, uHH) by weighted addition (1).

Abstract: A method for operating a braking system in a motor vehicle having at least two wheel brakes (54, 56), each of which can be activated by an electromechanical actuator of the self-locking type. Each wheel brake having a locking device for implementing a parking brake functionality, in which the locking device and respective electromechanical actuator is actuated and locked by the locking device when a parking brake function is carried out. A first method step is carried out in which the at least two actuators are actuated in succession and a second method step is carried out in which it is checked whether the at least two actuators have achieved respectively predefined brake application force. In the event of the at least two actuators have achieved the respectively predefined brake application force, the at least two actuators are locked in a third method step.
