摘要： In normal operation, a sensor element emits information only as to whether two or more field-sensitive components are located in peripheral zones of identical or different electromagnetic field strengths of a pulse generator. In order to permit sensor elements of this type determining immediately upon activation of a supply voltage whether an identical electromagnetic field strength on both components corresponds to a zone of low (L) or high (H) field strength, according to the present invention, the sensor element, upon activation of the supply voltage, is initially operated so that the absolute field strength is measured for a given time. If there is a difference circuit between two field-sensitive components (3, 4), the measurement is carried out because one of the components is temporarily switched off, both components are connected in parallel, or both components are connected in series.

摘要： In so-called active sensors which transmit an output signal to an electronic controller, the amplitude of the output signal depending neither on the speed of the encoder nor on the distance between the sensor and the encoder, the problem is that the output signal does not permit identifying whether the air slot size set between the sensor and the encoder is chosen sufficiently small to ensure an appropriate amplitude of the input signal, generated in the sensor, even when dynamic increases in the air slot occur. If the input signal induced by the encoder in the sensor is too low, a sensor-inherent hysteresis threshold is not exceeded, and no output signal is generated. To prevent the sensor from being inadvertently operated at the limits of its maximum permissible air slot, according to the present invention, the sensor-inherent hysteresis threshold is changed over to the higher hysteresis threshold for testing purposes. If a sufficient input signal is generated even by way of this higher hysteresis, it may be supposed that the sensor is correctly mounted.

摘要： To control a brake slip control apparatus, the rotational behavior of the wheels or of the axles is sensed with the aid of sensors, and the sensor signals for the generation of valve control signals, by which the braking pressure at the wheels is controlled dependent upon the wheel rotational behavior, will be processed electronically. On the basis of these sensor signals, valve control signals will be produced in at least two independently acting, synchronously driven logical circuit units, which may be integrated circuit configurations or complete "microcontrollers" or single-chip-microcomputers, and the signals' waveforms of each of the two circuit units can be compared and checked for agreement externally and internally at corresponding locations within the two circuit units. Upon the occurrence of variations in the external and/or the internal signals or in the signals' waveform, there will be caused, initiated or prepared a complete or partial disconnection of the brake slip control. A circuit configuration for implementing this method comprises a synchronizable astable multivibrator to process the sensor signals, a valve driver circuit including a level adjusting circuit as well as monitoring circuits for disconnecting the current supply for the regulator and for blocking the valve drivers in the event of interferences or variations in the signals' waveform occurring within the two circuit units. The monitoring circuits, one for each of the two circuit units, act on at least one transistor connected in series in the exciter circuit of a relay, by which the current supply is established or interrupted.

摘要： A circuit configuration for editing, or processing the output signal of a speed sensor (5) includes a trigger circuit (1, 22), the changeover points or "hysteresis" of which are controllable, with the circuit configuration being furnished with circuits for determining the coupling factor (k), and with circuits for adjusting the hysteresis in response to the coupling factor. The coupling factor (k)--multiplied by the frequency of the sensor signal corresponding to the speed--forms the amplitude of the sensor output signal. With the coupling factor (k) being high, the hysteresis will be high, while it will be low with a low coupling factor.

摘要： This is a circuit configuration provided for an anti-lock-controlled brake system and serving for processing sensor signals obtained by wheel sensors (5) and for generating braking pressure control signals. This circuit configuration contains two microcontrollers (1, 2) interconnected by data exchange lines (7). The handled signals are concurrently processed by the microcontrollers independently of one another and the exchanged signals are checked for consistency. A deviation of the exchanged signals which is due to malfunctions is signalized to a safety circuit (8) which, thereupon, interrupts the power supply to the solenoid valves (Ll . . . Ln). The monitoring signal (WD1, WD2) fed to the safety circuit (8) is a predetermined alternating signal in case of consistency of the exchanged signals and in case of proper operation of the circuit configuration. The safety circuit (8) compares the alternating signal with a time standard derived from a clock generator (TG2, TG3) which is independent of the operating cycle (TG1) of the microcontrollers (1,2). A change in the alternating signal, as well as a failure in the time standard, causes a cut-off of power supply and, hence, of anti-lock control.
