摘要： This disclosure relates to a method and an arrangement for filtering disturbing signals in the digital measurement of the cycle duration for an antiskid control system for motor vehicles. The detrimental influence of short disturbances on the production of control signals is suppressed by means of the filtering process. The production of the control signals takes place in accordance with the result obtained from a comparison of the respective measured value .tau..sub.n with a reference value .tau..sub.B. The filtering is carried out in a manner so that when a digital measured value .tau..sub.n enters, a new reference value .tau..sub.B', is produced as a function of the difference between the reference value .tau..sub.B and the mean value obtained from the reference value .tau..sub.B and new measured value .tau..sub.n.

摘要： A wheel speed measuring apparatus is provided for use in an anti-skid brake control system such that a digital speed signal is obtained having good accuracy without resorting to expensive manufacturing methods to assure exact conformity of the teeth and teeth spaces of the rotor member of the wheel sensor device used in the anti-skid control system. The speed measuring apparatus consists of at least two corresponding portions, each consisting of a control unit, a counter and a data register. The control unit of one portion responds to a positive polarity transition of the square wave signal generated by the wheel sensor, while the control unit of the other portion responds to negative polarity transitions, to initiate operation of the respective counters. The count output of each counter therefore provides a digital speed signal corresponding to a full cycle duration of the square wave signal, with one cycle overlapping the other to compensate for any deviations in the half-cycle durations due to size differences in the teeth and spaces of the rotor member of the sensor that generates the square wave signal.

摘要： An antiskid control system for a vehicle in which acceleration and deceleration control signals are generated by a control circuit in accordance with the rotational speed of a wheel monitored by a sensor device that produces a pulse train whose frequency varies with wheel speed. A digital counter operates for the duration of each pulse cycle of the sensor signal whereby the pulse count obtained represents a cycle duration of the sensor signal. Within the control circuit to which the sensor signal is supplied, a control unit transfers the pulse count after each cycle to a first shift register as a measure of the cycle duration. The first shift register outputs the pulse count of the measured cycle duration to a comparator to which there is also connected a pulse count of a reference cycle duration supplied by a second shift register to which the pulse count of a previous measured cycle duration has been supplied by the first shift register to form the reference cycle duration. The reference cycle duration and measured cycle durations are compared to obtain a difference signal which is subsequently compared to an admissible difference signal to provide the acceleration and deceleration control signals when the difference exceeds a preselected amount. The admissible difference is formed as a fraction of the reference cycle duration by selecting an output of the second shift register corresponding to a preselected stage thereof.

摘要： A circuit for the surveillance of the switching state of a power transistor is constructed such that both, the voltage applied to the power transistor (1) is surveyed by way of a voltage comparator (7), as well as the voltage applied to the load (3) is surveyed by way of a further voltage comparator (8). The comparator (7) in the switched-on state and the comparator (8) in the switched-off state are activated by the input signal (U.sub.IN) of the power transistor (1). The output signals of the two comparators (7, 8) are combined to a status signal (U.sub.Stat). It is possible by way of the proposed circuit to recognize both a short circuit or, respectively, a shunt circuit of the load as well as a leakage current of the power transistor (1) and thus an interruption of the load occurs.

摘要： A digital speed detecting circuit of the type in which pulses of a clock frequency are counted during a time interval of a cycle of the sinusoidal signal obtained from a sensor of the rotating member whose speed is being measured. The pulse count throughout the speed range of the rotating member is adjusted to be within a range best suited for accurate evaluation, since the pulse count exceeds this range at high and low speeds. This is accomplished in a first embodiment by shifting to a different counting frequency in different speed ranges and correcting the speed signal obtained by a factor corresponding to the degree of frequency change. In a second embodiment, the counting frequency is monitored and adjusted each cycle of the sinusoidal signal by comparing in a shift register the stage of advancement of a binary counter that produces the pulse count with a reference stage establishing the upper limit of the evaluation range. The frequency adjustment required each cycle depends upon the speed range of the rotating member and is monitored to provide a correction factor by which the speed signal is adjusted in accordance with the time required to shift the most significant bit of the shift register signal to the reference stage. In the third embodiment, the time interval of the sinusoidal sensor signal is increased in binary steps associated with different speed ranges of the rotating member so that the pulse count is registered during each speed range for various durations.

摘要： A circuit arrangement for influencing the brake pressure venting phase and/or brake pressure retaining phase for an antiskid vehicle braking system when the measured velocity difference deviates from a given velocity difference during controlled braking. The velocity change is determined as a function of the wheel tendency or tendencies by measuring and differentiating the velocity value or values at the interval boundaries of an assigned time .DELTA.t of the control signals or by the assigned times of the control signals. A switching circuit, to which the brake pressure control signals, such as, the acceleration +b, deceleration -b and slip .lambda. control signals, and a signal representing the wheel tendencies, such as, either positive or negative velocity change of the sensed wheel or wheels, can be set upon drop away of a +b or -b signal. The switching circuit controls a shifting circuit which changes the assigned time .DELTA.t or some or all assigned times .DELTA.t or changes the switching times of the control signals as a function of the signal or signals indicating the wheel tendency or tendencies. Thus, the shifting circuit produces a high signal, a medium signal, or a low signal indication representing an appropriate assigned time .DELTA.t.

摘要： In an anti-skid brake control system for a wheeled vehicle, an electronic circuit for generating a wheel speed signal in accordance with the time duration of a half cycle of a sinusoidal waveform generated by a sensor that detects the presence or absence of teeth of a rotor that revolves with a wheel of the vehicle is arranged so that the measured time duration of both a positive and a negative alternation of the waveform is utilized to obtain accurate wheel skid control at relatively low speeds. Slight differences in the measured time duration of a positive and negative half cycle due to slight variations in the dimensions of a tooth and adjacent space are sensed and modified as required to assure correspondence between the measured time durations in order to avoid false sensing of a wheel skid condition.
