摘要： In a method of controlling the brake pressure in the rear wheel brakes of a double-track vehicle, wherein the rotational speeds at least of the rear wheels are measured and the brake pressure is lowered, kept constant, or raised, depending on the unstable or stable states arising at the individual rear wheels, the pressure in the brake of a stable rear wheel being approximated at least temporarily to the pressure in the brake of an unstable rear wheel, it is provided that, upon initiating a pressure decrease in the brake of an unstable rear wheel, the pressure in the brake of the stable rear wheel is kept constant for a predetermined period of time (.DELTA.t) and then decreased until the pressure in the brake of the unstable wheel is either kept constant or increased. This guarantees shorter stopping distances and at the same time provides a smaller difference in the braking torques at the rear axle, at good stability of the motor vehicle.

摘要： A method of controlling the brake pressure in an anti-lock vehicle braking system provides for determining the deviation of a control magnitude, such as the slip or retardation of a wheel, from a given rated value Sw in the course of a control cycle. A threshold value which is decisive for the pressure decrease at a wheel subject to the risk of becoming locked is changed for the next successive control cycle in response to the amount of the deviation of the control magnitude from the rated value.

摘要： An anti-lock braking system is specifically designed for a motor vehicle having four-wheel drive and a device for shifting between two-wheel and four-wheel drive incorporating a lockable central differential. Additional differentials at the front and rear axles may also be locked to avoid wheel spin. The anti-lock braking system produces a brake pressure reduction signal when the wheel speed falls below a reference value. In accordance with the invention the reference value is varied in dependence upon whether the vehicle is shifted into two-wheel or four-wheel drive, in dependence upon the engagement of the central differential lock, and/or in dependence upon the engagement of the other differential lock(s).

摘要： To extend the range of automatic control of a brake anti-lock system, wheel speeds (V.sub.R1 -V.sub.R4) are processed and changed into control signals (12, 15) controlling braking effort of the vehicle. A first predetermined vehicle reference speed (V.sub.REF) is provided, and compared with a computed or actual vehicle speed. If the computed or actual vehicle speed drops below the first reference level (V.sub.REF1), a transfer switch (25) changes over control of the braking pressure control unit (22) from the standard control unit (23) to an auxiliary or additional branch (26) which initially maintains braking pressure, but drops braking pressure if the wheel speed of an individual wheel drops below a minimum level (V.sub.min) and the actual vehicle speed is above a second reference level (V.sub.REF2), which second reference level is below the first reference level (V.sub.REF1). The second reference level (V.sub.REF2) corresponds to a speed in excess of the minimum (V.sub.min).

摘要： To provide for close adaptation of braking performance by braking pressure maintenance, braking pressure dropping, or braking pressure increase to match wheel acceleration or deceleration, and operating constants within the overall braking system, the wheel anti brake-lock responds when wheel deceleration drops below a predetermined reference threshold. Wheel speed is sensed in steps, for example in intervals of 0.25 km/h, and the steps are counted. A predetermined brake pressure decrease time (t.sub.min) is initiated when wheel speed drops below the reference wheel speed, the total time (t.sub.a) of pressure decrease being the minimum time plus a number of first control time intervals (.DELTA..sub.1t) which depend on the number of speed steps being passed by the wheel as it decelerates. If the wheel speed, after the pressure decrease, does not decelerate at the same rate anymore, a pressure maintenance phase is commanded for a maximum time (.DELTA..sub.2t) which, however, is foreshortened by second control timing intervals (.DELTA..sub.2t) in dependence on the wheel passing further speed steps or stages. If the wheel should decelerate substantially (.lambda..sub.2) or drop below a deceleration threshold (-b), a further pressure decrease phase can be immediately initiated, overriding the pressure maintenance phase. The first and second control timing intervals can also be made dependent on each other.

摘要： A method of controlling the brake pressure in an anti-lock vehicle brake system provides for short distances to stop to be reached even with greatly differing mass moments of inertia by calculating the pressure reduction period of a control cycle currently under way as the product of a first factor and a second factor. The first factor depends on the pressure reduction period in the preceding control cycle, and the second factor depends on the maximum re-acceleration of the wheel in the preceding control cycle.

摘要： In a method of controlling the brake pressure of a vehicle brake system equipped with anti-lock protection it is provided to measure the slip and/or rotational retardation of a wheel whose brake is applied and to compare each measured value with a given threshold value so as to lower the brake pressure if the threshold value proves to have been surpassed. Undesired pressure reductions can be avoided by increasing the threshold value for given periods of time from a basic value (S.sub.G) and subsequently decreasing it again. At a point in time T.sub.1 at which the rotational retardation of the braked wheel is greater than a value corresponding to a physically feasible slowdown of the vehicle the threshold value is increased abruptly, to be decreased thereafter according to a predetermined function of time. During the lowering of the threshold value the change in speed of the retarded wheel is measured over given intervals of time .DELTA.T and compared with the instantaneous higher threshold value. If the comparison demonstrates that the change in speed in question is greater than the instantaneous raise in threshold value, the threshold value is reduced to the basic value (S.sub. G).

摘要： For measuring the rotational speed of a wheel in an antilocking protected vehicle brake system a rotational speed sensor is provided in which in accordance with the rotational speed of the wheel signals are electromagnetically induced which have an amplitude and frequency which increase regularly with the rotational speed. When due to error sources the amplitude of the induced signal does not increase with the frequency of the signal a rotational speed measured value is determined by means of the measured amplitude, i.e. not on the basis of the measured frequency. To avoid erroneous measuring signals it may likewise be provided that when the amplitude of the signal does not increase with its frequency the last measured value of the frequency of the induced signal at which the amplitude still increased with the frequency is used to determine the speed of rotation.

摘要： A method of controlling the brake pressure in an antilock (ABS) vehicle brake system provides for adapting the wheel at which the brake is applied to the optimum course of the coefficient of friction/slip curve by determining the rotational retardation of the braked wheel, upon initiation of a braking action, after given time intervals each and comparing it with the rotational retardation of the preceding time interval. Moreover, the brake pressure is varied in response to the result of the comparison. The renewed acceleration of the retarded wheel also is monitored accordingly so as to effect further lowering of the brake pressure if the renewed acceleration or the gain in acceleration is too small.
