摘要： A brake control system is described that prevents a wheel lockup condition by identifying the brake pressure that produces the maximum possible braking effort during each brake pressure application period and applying a predetermined fraction of the identified pressure after an incipient wheel lockup condition is sensed. One criteria for sensing an incipient wheel lockup condition is the decrease in the braking effort from the maximum possible braking effort by a predetermined amount as wheel slip increases from a critical slip value.

摘要： A wheel lock control system is described for a wheel braking system in which the brake pressure producing the critical slip value and therefore the peak braking effort is precisely determined. The brake pressure that is reapplied following an incipient wheel lockup condition is determined as a function of (A) the brake pressure and wheel deceleration corresponding in time to the peak calculated tire torque tending to accelerate the wheel during braking prior to the detection of an incipient wheel lockup condition and (B) the brake pressure and wheel acceleration corresponding in time to the peak calculated tire torque tending to accelerate the wheel during wheel speed recovery following an incipient wheel lockup condition. By using these parameters, the precise brake pressure for establishing the critical wheel slip is determined so that the maximum braking effort may be established following a detected incipient lockup condition.

摘要： A hydraulic brake-power booster unit is provided for a vehicle having a dual-circuit brake system and an antilock system operating according to the drain principle. When the brake system is intact, the booster unit provides dynamic pressure to one of the two brake circuits and static pressure admission to the other. The pressure to the static brake circuit takes place by the separate-power-assisted shifting of an emergency piston. On one side, the emergency piston delimits an output pressure space to which the brake circuit that can be statically acted upon by pressure is connected. This brake circuit also remains operable in the case of a breakdown of the hydraulic power source only by the operation of the pedal and the resulting possible shifting of the emergency piston. A path transducer generates an electrical signal proportional to the position of the emergency piston. A pressure transducer generates an electrical signal proportional to the pressure in the output pressure space for the static brake circuit. Starting from a minimum position of the emergency piston, the brake circuit that initially could be acted upon statically by pressure is now acted upon dynamically. The reversing is caused by a mechanically path-controlled reversing valve. When the actual value of the output pressure of the brake-power booster unit is lower than a desired value, an electronic comparison arrangement generates a warning signal.

摘要： A control circuit for adapting slip control of an anti-skid brake system of an automotive vehicle comprising a friction coefficient identification circuit (31, 31'). Upon the instabilization of a wheel the braking pressure control signals controlling the slip by actuating solenoid valves (36-41) are varied by the output signal of the circuit (31, 31') as a function of the momentary deceleration (v.sub.R) of the fastest wheel and/or on the momentary pressure in the hydraulic brake circuits (52, 53, 54) and thus are adapted to the momentary friction coefficient, which in particular depends on the road condition. In one instance, the gradient of the vehicular reference velocity is varied in dependence on the friction coefficient.

摘要： The present invention concerns a control valve for use in a vehicle anit-lock braking systm adapted to control the application of pressurized brake fluid to at least one selected vehicle brake. The valve includes an outer housing having an inlet coupled to receive pressurized brake fluid from the vehicle master cylinder and an outlet coupled to supply pressurized brake fluid to the selected vehicle brakes. A passageway is formed in the housing for connecting the inlet to the outlet. A normally open isolation valve is located in the passageway and is utilized to control the flow of fluid through the passageway between the inlet and the outlet. When an incipient wheel lock condition is detected, the isolation valve can be closed to prevent a further increase in pressure to the controlled brakes and to hold the pressure supplied to the controlled brakes at a relatively constant level. After the isolation valve has been closed and it is desired to further increase the pressure to the controlled brakes, the valve can be momentarily opened to enable increased pressure from the vehicle master cylinder to be supplied to the controlled brakes. In accordance with the present invention, a damping mechanism is associated with the isolation valve for damping the movement of the valve as the valve is moved from the closed position. It has been found that such damping enables the reapplication of pressure to the selected brakes to be more precisely controlled.
摘要翻译：本发明涉及一种用于车辆安全锁定制动系统中的控制阀，其适于控制对至少一个选定的车辆制动器的加压制动液的应用。该阀包括外壳，该外壳具有联接以接收来自车辆主缸的加压制动液的入口和连接到向所选择的车辆制动器供应加压制动流体的出口。在壳体中形成有将入口连接到出口的通道。常开的隔离阀位于通道中，用于控制流体通过入口和出口之间的通道。当检测到初始车轮锁定状态时，可以关闭隔离阀，以防止对受控制动器的压力进一步增加，并将供给控制制动器的压力保持在相对恒定的水平。在隔离阀已经关闭并且期望进一步增加受控制动器的压力之后，阀可以被暂时打开，以使来自车辆主缸的增加的压力被提供给受控制动器。根据本发明，阻尼机构与隔离阀相关联，用于当阀从关闭位置移动时阻尼阀的运动。已经发现，这种阻尼使得能够更精确地控制对所选制动器的压力的再次施加。

摘要： To maintain stability of operation of a vehicle entering a curve, for example with excessive speed upon entering the curve, and application of the vehicle brakes by the operator, the braking effort (P.sub.HA) applied to the rear wheels or rear axle of the vehicle is controlled to be at a low and constant level, substantially below the braking effort (P.sub.VL, P.sub.VR) applied to the front wheels of the vehicle, and for a limited period of time (t), which may be a predetermined time duration, under control of a timing element (4), or which may depend on counted braking cycling events, of braking effort applied to the front wheels, for example under control of an anti-brake locking or blocking system (ABS). For example, a counter (8) may count two cycles of operation of the ABS and then release the low, constant braking effort phase applied to the rear wheels of the vehicle. Stability of operation of the vehicle, in the curve, is thus maintained.

摘要： A vehicle brake and wheel anti-lock control system in which an electronically controlled actuator normally provides brake pressure for the vehicle wheel brakes and also acts as a modulator to vary the brake actuating pressures for wheel anti-lock control. The actuator is so arranged that a master cylinder may be used to provide actuating pressure to the wheel brakes, the pressure passing through the actuator pressurizing chamber, if for any reason the actuator does not perform as needed to provide brake actuating pressure to stop the vehicle.

摘要： To prevent oscillation of a wheel being intermittently braked in an anti-slip or anti wheel block system, an increase of braking pressure, after a prior decrease, is controlled to occur during a first time interval which is short with respect to an oscillation period of the wheel if subjected to brake pressure pulses, so that the braking pressure increase will be small or short, e.g. about 3 milliseconds, comparable to stepped pressure increases after an initial wheel deceleration and permitted re-acceleration, the pressure then being maintained at an even level for an interval (T.sub.3) which, likewise, is short with respect to the intervals (T.sub.0, T.sub.4) between stepped increases. The respective time intervals can be controlled by individual, special pulse generators, or by suitable programming of microprocessor elements.
