    • An anti-lock brake system is described in which, when an instability limit IS is exceeded by an instability criterion KK=aB+b.multidot.L+cIL+dV.sub.F(where a, b, c and d are constants and B is the relative wheel deceleration, L is the wheel slip and IL is the integral of the wheel slip and V.sub.F is the calculated vehicle deceleration, a pressure reduction pulse is produced, the width of which depends on the reduction time in the preceding cycle. This pulse also resets the integrator and the differentiator required for obtaining the wheel deceleration to 0. Between the pressure reduction pulses, pressure is held constant.

    • The present invention concerns a vehicle anti-lock brake control system which does not require the use of an auxiliary hydraulic pump and, in the preferred embodiment, is adapted to control only the rear brakes of a four-wheel vehicle. The control system includes a normally open solenoid actuated isolation valve connected between the master cylinder and the rear wheel brakes, and a normally closed solenoid actuated dump valve connected between the rear wheel brakes and a fluid accumulator. A computer control is connected to monitor the rear wheel speed and deceleration and, during breaking of the vehicle, functions to control the application of hydraulic pressure to the rear brakes via the isolation and dump valves in order to prevent lock-up of the brakes. In the event excessive rear wheel deceleration is detected during a vehicle stop, the computer control closes the isolation valve to hold pressure to the rear brakes at a relatively constant level. If, after the isolation valve has been closed, the difference between the actual rear wheel speed and a calculated theoretical speed ramp valve exceeds a predetermined slip threshold, the dump valve is selectively opened to reduce pressure to the rear brakes and correct the wheel slip condition. The computer control is adapted to monitor several operating parameters while the system is in the anti-lock mode in order to determine whether additional pressure should be applied to the rear brakes by selectively opening the isolation valve.
    • 本发明涉及不需要使用辅助液压泵的车辆防抱死制动控制系统,并且在优选实施例中,仅适用于仅控制四轮车辆的后制动器。 控制系统包括连接在主缸和后轮制动器之间的常开电磁致动隔离阀,以及连接在后轮制动器和流体蓄能器之间的常闭电磁致动卸载阀。 连接一台计算机控制器来监控后轮速度和减速度,并且在车辆断开期间,通过隔离和排放阀控制对后制动器的液压的应用,以防止制动器锁止。 在车辆停止期间检测到过大的后轮减速度的情况下,计算机控制器关闭隔离阀,以相对恒定的水平保持后制动器的压力。 如果在隔离阀关闭之后,实际的后轮速度与计算的理论速度斜坡阀之间的差超过预定的滑移阈值,则选择性地打开倾卸阀,以减小后制动器的压力并校正车轮滑动条件 。 计算机控制器适于在系统处于防抱死模式时监视多个操作参数,以便通过选择性地打开隔离阀来确定是否应该对后制动器施加附加压力。

    • An anti-skid control apparatus for diagonally connected vehicle wheels including control valve devices arranged between fluid pressure generating chambers of a tandem master cylinder and the wheel cylinders of the front wheels, respectively, and a control unit receiving outputs of speed sensors for judging the skid conditions of the wheels and for instructing the control valve devices. The control unit determines the frictionally lower side of the road on which the wheels are running, and combines logically the judging result of the skid condition of the rear wheel running on that side of the road, with that of the front wheel running on that side. The apparatus then generates instructions for controlling the first or second valve device for the corresponding front wheel, and for controlling the second or first valve device for the other front wheel, on the basis of judging the skid condition of the other front wheel running on the other side of the road independently of the rear wheels. Alternatively, the apparatus may judge skid conditions of the rear wheels and the skid condition of one front wheel running on one side to control the valve device for the corresponding front wheel, and generate instructions to control another valve device for the other front wheel after judging the skid condition of the other front wheel running on the other side of the road.

    • In an anti-skid control system for a motor vehicle, brake fluid pressure reduction-control mode and brake fluid pressure buildup-control mode occurs cyclically; in the reduction-control mode, reduction of the brake fluid pressure is started on the basis of detection of an abrupt drop in wheel speed which occurs when the wheel is braked; and in buildup-control mode, a valve is repetitively opened and closed so that brake fluid pressure buildup and holding operations are performed alternatley and repetitively, whereby the brake fluid pressure is caused to build up gradually. The length of time period for the first buildup operation in the buildup-control mode is determined on the basis of variation in the wheel speed occurring between a low peak point and a high peak point; and the length of time period for at least one of each pressure holding operation and each of the second and succeeding pressure buildup operations in the abovementioned buildup-control mode, is determined on the basis of variation in the wheel speed occurring immediately before the pressure holding or buildup operation is started.

    • A method and device for controlling the variation of braking pressure in the wheel cylinders of brake-slip controlled vehicle brakes. The wheel rotational behavior (v.sub.Rad) and further a vehicle reference velocity (v.sub.Ref) are determined by sensors and logically combined to produce control signals. The braking pressure at the wheels is controllable by the operation of electromagnetically actuated valves (AV, EV) inserted in the pressure fluid circuit. A first pressure-decrease pulse is triggered as soon as the wheel velocity exceeds a deceleration or slip threshold during a braking action. The duration of the said pressure-decrease pulse is determined by the instantaneous deceleration upon attainment of the first switching threshold. Any subsequent pressure decrease pulse is delivered only after a predetermined waiting period and is of a duration determined by reference to the average acceleration.

    • An anti-lock brake device for use with wheel brakes connected to wheels of a vehicle is disclosed having a hydraulic pressure control circuit for controlling the application of hydraulic brake pressure to the wheel brake and a control element for detecting whether the wheels are likely to lock from rotational velocity characteristics of the wheels and operating said hydraulic pressure control circuit to reduce said hydraulic brake pressure applied to said wheel brakes when said wheels are likely to lock. The control element further includes a decision circuit for outputting a signal on the assumption that one condition for reducing the hydraulic brake pressure has been satisfied when the wheel velocity is lower than a reference wheel velocity, and a delay circuit for outputting an operating signal for nullifying the signal output from the decision circuit until a predetermined period of time has elapsed after the signal is received from the decision circuit.
