Abstract: Disclosed is a process for operating a brake actuation unit of a motor vehicle brake system of the ‘brake-by-wire’ type. The brake system has a brake booster, a master brake cylinder, and a pedal travel which interacts with the brake pedal and due to a resetting force acting on the brake pedal can be simulated in the ‘brake-by-wire’ operating mode independently of an actuation of the brake booster, and which can be enabled in the ‘brake-by-wire’ operating mode when the force-transmitting connection between the brake pedal and the brake booster is decoupled and can be disabled outside the ‘brake-by-wire’ operating mode. In order to minimize a constructively predetermined axial slot ‘a’ between the end of a piston rod 10 coupled to the brake pedal 1 and a control piston 11 of the control valve 9 of the brake booster 3 in regenerative brake operations, while a predetermined actuating travel of the brake pedal (1) is covered, where actuation of the brake booster (3) is not intended, software-related technical measures are performed immediately before a force-transmitting connection between the brake pedal (1) and the brake booster (3) occurs, which prevent the force-transmitting connection between the brake pedal (1) and the brake booster (3).

Abstract: To improve the control behavior of an automotive vehicle control system, such as an anti-lock system (ABS), a driving stability control system (ESP, ASMS, DDC), etc., in a brake system which includes a master cylinder, inlet and outlet valves for pressure modulation, a low-pressure accumulator, and a hydraulic pump for returning the pressure fluid discharged, when a wheel becomes unstable and upon commencement of the ABS control, that branch of the control system to which the unstable wheel is connected is temporarily uncoupled from the master cylinder pressure (pHZ) or initial pressure by closing the pressure fluid conduit in the direction from the wheel brakes to-the master cylinder, and a relatively quick rise of the braking pressure and a quick approach of the wheel braking pressure to the master cylinder pressure (pHZ) and, thus, the wheel lock pressure level is caused by returning pressure fluid from the low-pressure accumulator into this branch. A special valve which can provide a connection between the master cylinder and the suction side of the hydraulic pump is switched over to open-passage-only after the low-pressure accumulator has been emptied at least in part, or as required.

Abstract: In a cornering identification method which, in particular, is provided for automotive vehicles with anti-lock control or traction slip control, the rotating velocities of the two wheels of the one (non-driven) axle are measured and a correction value is continuously determined for the difference in the rolling circumferences of the tires of the two wheels. A reference value (THR) is developed which is representative of a straight-line course and, in accordance with a predetermined time pattern, this reference value is continuously corrected in dependence on the velocity difference of the two wheels. For cornering identification, a velocity difference value (DIF) is compared with the reference value (THR). At the beginning, i.e., after the start of cornering identification, the reference value (THR) will be corrected in relatively short periods which will be prolonged as the ride goes on. The rate of change (.DELTA. THR) of the reference value (THR) is likewise high at the beginning, decreasing thereafter.

Abstract: A circuit configuration for a brake system with anti-lock control and/or traction slip control including circuits (4) for improving the control during cornering. In the presence of a wheel rotational behavior typical of cornering when during a control action the wheel slip, that means the deviation of the wheel speed from the vehicle reference speed, exceeds the slip threshold (SO), this wheel rotational behavior lasting despite reduction of the braking pressure and the deceleration-responsive/acceleration-responsive control thresholds not being attained, the wheel slip is augmented by an offset (.DELTA.SO) for an invariably preset period of time or a period of time which is dependent on the further wheel rotational behavior, on the braking pressure variation and/or other control criteria.

Abstract: The invention discloses a method for determining the air content of the brake fluid in a hydraulic braking system. This method also permits determining the quality of the bleeding of the braking system.The principle of the method is a comparison of the volume intake with the respectively achieved pressure. The correlation is compared to nominal values. As the volume intake is determined by the clearance, the system is set by means of a pre-actuation to an initial condition before each actual measurement.

Abstract: The present invention relates to a method and a device for monitoring a brake system for motor vehicles equipped with an electronic controlling and regulating unit, as well as a hydraulic pressure accumulator that is used as an auxiliary pressure source and subdivided by a media-separating element into two chambers, the first chamber being filled with a gas and the second chamber being filled with a liquid pressure medium. To conduct a reliable monitoring of the pressure accumulator, the invention provides that the number of the partial strokes of the media-separating element is detected. To this end, brake actuations are weighted and counted according to their duration and intensity. When the sum of the weighting factors reaches a predetermined number, a warning indicates an imminent damage to the media-separating element. This renders it possible to use a less costly and less sensitive media-separating element, which obviates the need for extensive protective measures against mechanical loads.

Abstract: A slip-controlled hydraulic brake system for all-wheel driven motor vehicles equipped with lockable differentials (2, 3) is provided with sensors (S.sub.1 -S.sub.4, 33-36) for measuring the rotational behavior of the wheels. Electronic circuits (44) are provided for logic combining and processing the sensor signals, and for generating braking pressure control signals by way of which the brake pressure in the individual wheel brakes (16-19) is variable in response to the rotational behavior of the wheels and to a reference variable. To compensate the increased moments of inertia as a result of the moments transmission, by way of the lockable differentials (2, 3) in this brake system the brake pressure in the rear-wheel brakes (18, 19), can be modulated at a lower control frequency as compared with the brake pressure in the front-wheel brakes (16, 17). The reduction in the control frequency of the rear-wheel brake pressure is determined by driving-dynamic criteria, for example, by the average motor vehicle deceleration or by the motor vehicle speed.
