Abstract: To improve the control behavior of an ABS system in an off-road travel situation, a special control mode is activated as soon as such an off-road travel situation is identified. To this end, braking pressure reduction on the wheel of a vehicle axle which is the first to exceed the normal control thresholds is prevented, different from the normal control mode, and the braking pressure on this wheel is maintained constant until reacceleration of this wheel commences. Starting from this time, braking pressure increase is allowed in the wheel brake of this wheel until the normal control thresholds are reached and the special control mode is terminated. The normal control mode applies to the second wheel of the axle concerned as long as the special control mode applies to the first wheel. Subsequently, the special control mode can pass on to the second wheel of the axle, and the first wheel will then ensure that steerability and/or driving stability is maintained.

Abstract: The present invention discloses a method for use in automotive vehicles with an electronically controlled brake system (for example, ABS), wherein for controlling the braking pressure (re)increase during a control operation the rotational behavior of the individual wheels is measured and evaluated to determine braking pressure control signals, and wherein during a braking pressure control operation the braking pressure reduction in the previous cycle (26) is taken into account for the control of the braking pressure reincrease (27). According to the present invention, a braking pressure rise gradient (G) is calculated on the basis of the braking pressure increase in the preceding braking pressure increase phase (25), and the braking pressure increase or the variation of the braking pressure increase is calculated and predetermined on the basis of the rise gradient (G) and the calculated wheel cylinder pressure (P2) at the commencement of the current braking pressure increase phase (27) and on the basis of the current calculated locking pressure level (N3).

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 method for controlling an anti-lock braking system, intended for motor vehicles having all-wheel drive, electric signals representative of the rotational behavior of the vehicle wheels are produced and logically combined. When a locking tendency occurs, the braking pressure is controlled, and the instantaneous wheel slip, the wheel acceleration, and the wheel deceleration are evaluated as control criteria, and wherein the individual wheel speed is compared to a vehicle reference speed which is used as a reference quantity for controlling the braking pressure. In the event of a wheel rotational behavior that is typical of a spinning tendency and is revealed by a rise of the vehicle reference speed in excess of the actual vehicle speed, the control concept is modified up to a defined point of time in that the instantaneous wheel slip is left out of account as a control criterion for this spinning phase and the braking pressure control becomes dependent on merely the wheel acceleration or the wheel deceleration.

Abstract: A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure.
