摘要： A method and a circuit configuration for suppressing undesired control actions in slip-controlled brake systems, which, for example, may be caused by oscillations of the axle. The wheel rotational behavior is determined and the braking pressure is controlled in dependence upon slip criteria and/or acceleration criteria, and slip control commences when predetermined threshold values (-b.sub.N) are exceeded. A threshold value decisive for initiation of the control is varied as a function of re-acceleration of the controlled wheel.

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： An anti-skid brake control system controls the operation mode of a pressure control valve in a hydraulic brake circuit for increasing the fluid pressure in its application mode, for decreasing the fluid pressure in its releasing mode and for holding the fluid pressure at a constant value in its holding mode. The control system has a predetermined operation pattern in which the operation modes of the pressure control valve cycle through a predetermined schedule. Measured wheel acceleration and slip rate values dictate which operation modes are to be selected next and when the change from mode to mode should be performed. When the operation mode is to be changed, the next operation mode selected is checked to see if it is consistent with that scheduled. When the selected operation mode is different from the scheduled one, the selected operation mode is modified to perform the operation according to the scheduled operation mode which would otherwise be skipped.

摘要： In an antiskid control system for the hydraulic braking system of a wheeled vehicle, the rotational speed of a vehicle wheel and the acceleration of the wheel are detected and levels of road surface friction are determined on the basis of the wheel speed and acceleration to give a first indication that the road has a high value of friction or a second indication that the road has a low value of friction. The wheel speed and acceleration are analyzed to detect a down-pressure mode to decrease the fluid pressure of the braking system and an up-pressure mode to increase the pressure. In response to the presence of the first indication, the down-pressure mode is effected at a lower rate and then at a higher rate. In response to the occurrence of the second indication, the down-pressure mode is effected at the higher rate.

摘要： An anti-skid brake control system comprises a detector for detecting the peak value of wheel acceleration in each cycle of skid control. Braking pressure is increased in step-wise fashion by alternately operating a pressure control valve between an application mode in which working fluid is supplied to a wheel cylinder to increase the braking pressure and a hold mode in which the wheel cylinder is blocked from fluid communication to a hydraulic brake circuit to hold the braking pressure constant. The duration for holding the pressure control valve in the application mode is adjusted depending upon the detected peak value of wheel acceleration, whereby an average increasing rate of braking pressure is variable depending upon the peak value of the wheel acceleration.

摘要： In an antiskid control system the speed of a vehicle wheel is compared with a variable threshold which is a function of the speed of the vehicle and a first comparator output is generated when the speed is lower than the variable reference. The acceleration of the wheel is compared with a predetermined threshold for generating a second comparator output when the acceleration is lower than the threshold or a third comparator output when the acceleration is higher than the threshold. The fluid pressure of the braking system is lowered in response to there being a simultaneous presence of the first and second comparator outputs and raised in response to there being a simultaneous presence of the first and third comparator outputs.

摘要： This invention relates to an electronic sensor for determining the start time and duration of the brake relief phase in brake force modulation cycles in vehicles with so-called anti-lock brake systems. A tachometer detects the rotation speed of the wheels. A signal from the tachometer is compared to a reference signal from a reference value generator. A switch is controlled by an output signal from the comparator and in turn controls a brake force reduction operation of a brake force modulator. The slope of the reference signal may be controlled by a vehicle operating condition such as the modulated brake force.

摘要： To prevent erroneous operation of a wheel anti-skid or anti-brake lock system which is arranged to compensate for yaw of the vehicle if the wheels at the respective sides of the vehicle operate on portions of a road surface of widely different roughness, e.g. one side of the vehicle on a dry road track and the other side on ice or snow, upon movement of the vehicle through a curve during which a brake is applied, so that the yaw-prevention portion of the system might erroneously recognize movement through the curve as yaw, that is, rotation about a vertical axis through the vehicle, an accelerometer (36') is provided, connected to sense transverse acceleration of the vehicle, e.g. about a vertical axis, and inhibiting application of the yaw-preventing signals to the automatic braking system. Application of the yaw-preventing signals is inhibited by including an AND-gate (36, 35) in the yaw-preventing circuits (31, 30) so that, unless the AND-gate is enabled, signals from the yaw-prevention circuit will not be transmitted.

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.
