摘要： In an anti-lock vehicle braking system the brake pressure acting at the controlled wheel is controlled in such a manner that the threshold value with respect to the rotational retardation of the wheel at the beginning of a lowering or raising of pressure is increased briefly, during a control cycle, by a constant amount (S.sub.H -S.sub.G) with respect to a threshold base value (S.sub.G) in order to avoid any undesired control operations caused especially by axle vibrations, pot holes, and the like. The threshold value is then decreased in response to the period of time of the pressure reduction in the preceding control cycle. The decreasing of the threshold value is carried on to values S.sub.T below the threshold base value and maintained for a given time interval (t.sub.x -t.sub.y).

摘要： A method of controlling the brake pressure in an antilock vehicle brake system in which rotational velocities of the vehicle wheels are measured and the brake pressure is modulated in dependence upon the retardation and the slip of a wheel on exceeding threshold values provides that for each braked wheel the difference between the vehicle reference velocity and a wheel reference velocity is determined for adjusting the length of the pressure maintaining or pressure diminishing phase in dependence upon the difference.

摘要： The anti-wheel-lock control system has a wheel speed transducer (1), an evaluation circuit (3), and a braking pressure control device (4, 5).Particularly in commercial vehicles and at low speed, the vehicle wheel may exhibit frictional oscillations; these frictional oscillations appear as rapidly changing speed signals when sensed by the value transducer (1), which simulate sudden high wheel speed. The invention addresses the problem of eliminating these disturbances. The changes in the speed signals are physically impossible, and the disturbances are eliminated by a circuit (15, 16, 27, 28, 29) which recognizes physically impossible changes in the wheel speed by comparing the actual speed signals with a simulation threshold at which changes in speed are physically impossible. This recognition circuit triggers an auxiliary device (18, 24) upon the occurrence of the disturbance, and the auxiliary device provides an auxiliary wheel speed signal for the control device based on wheel speed measured most recently prior to the disturbance.

摘要： An anti-skid brake control system for a motor vehicle includes wheel sensors for producing signals representative of the rotational speed of each road wheel; an evaluation circuit responsive to the wheel speed signals for determining a reference speed that approaches the speed of the vehicle and for producing brake pressure control signals, in dependence upon the reference speed and the road wheel speeds; and a brake pressure controller responsive to the brake pressure control signals for varying the brake pressure applied to the road wheels. The evaluation circuit includes means for determining the vehicle speed from the average increase of the reference speed and this vehicle speed, so determined, is used to determine an increase in the value of the reference speed during periods of braking instability.

摘要： For measuring the rotational speed of a wheel is 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： An anti-locking brake system is described in which pressure drops produced in the event of rapidly succeeding wheel retardations and wheel accelerations are restrained. This is achieved by a summing circuit having a sum to which a numerical value is added; the sum is reduced according to a given function. The sum value present in each case is a measure of how the pressure reduction is to be restrained, for example, by raising thresholds.

摘要： An anti-locking brake control system for a motor vehicle comprises wheel speed sensors for determining the speeds of the individual vehicle wheels, an evaluation circuit which receives the wheels speed signals and generates brake pressure control signals, and a brake pressure control device responsive to the brake pressure control signals for controlling the brake pressure applied to the wheels. The evaluation (processing) circuit includes a brake pressure control unit which operates in such a manner that, after brake pressure decays, the brake pressure is first increased in a timed build-up with reference to the brake pressure build-up in a preceding control cycle, and thereafter the brake pressure is further increased by a sequence of pulses until an instability is again detected. The timed pressure build-up has at least two timed pressure build-up phases which have respective durations such that the duration of each one of the timed build-up phases in a given time pressure build-up is longer than the length of the subsequent timed build-up phase in the control cycle. In addition, the duration of the timed build-up is a function of the preceding pressure decay time, this function being such as to reduce the value of longer decay times relative to shorter decay times.

摘要： To provide an unambiguously representative signal responsive to the speed of a vehicle wheel, an inductive pick-up (1a. . . . 1n) is coupled to a suitable star wheel or the like of each one of the wheels, the pick-ups then providing their signals to amplifiers (3a. . . . . 3n) having hysteresis characteristics. At low speeds, an offset signal is superimposed on the voltage from the inductive pick-ups so that the amplifiers respond and provide output signals only at higher amplitudes of the pick-up signals, thereby eliminating inaccuracies or disturbances occurring in the sensor which might simulate changes in speed of the respective wheel.
