    摘要: An arrangement for sensing the rotational speeds of a wheel or any other rotating member includes a sensor module with a sensor element, a controllable current source with a modulator and a signal conditioning and evaluating circuit. The modulator controls the current source in response to the signals of the sensor element and/or external signals and, as an output signal of the sensor module, delivers a current signal representative of the rotational behavior with status or additional signals superposed on the current signal. The evaluating circuit of the sensor module includes at least two different signal-conditioning networks which, by way of a control network, in dependence on predetermined criteria or conditions, are connected between the sensor element and the modulator controlling the current source and take care of signal conditioning. The shift from one signal-conditioning network to another occurs in response to control signals which the control network derives automatically from the control of one of these networks, or in response to control signals which are sent to the control network by a signal-receiving external circuit outside the sensor module via the same signal line.

    摘要: To transmit data which is supplied by a rotational speed sensor in the form of an alternating signal as well as additional data via a signal line, a sequence of current pulses of a predetermined duration is derived from the alternating signal, the pulse intervals or interpulse periods containing the information on rotational speed. The additional data is transmitted in the interpulse periods, and transmission of the additional data is synchronized by the individual rotating signal sensor pulses. Preferably, the method is employed for active sensors, and both the sensor pulses and the additional data are transmitted in the form of current signals. During standstill, in the absence of a sensor pulse, transmission of the additional data is triggered by auxiliary synchronization pulses.

    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: A circuit configuration which serves to condition the output signal of a rotational speed sensor, e.g., the wheel sensor of an automotive vehicle. The circuit configuration includes a trigger circuit, the "hysteresis" or trigger thresholds thereof being controllable, and includes circuits for determining a coupling factor which, multiplied by the frequency of the sensor signal corresponding to the speed of rotation, forms the amplitude of the sensor output signal. To determine the coupling factor, and to adjust the hysteresis, threshold values are predefined for the output signal of the rotational speed sensor. Upon start of the vehicle, the coupling factor is determined from the frequency of the sensor signal at the point of time the threshold values are reached, and the hysteresis is adjusted accordingly.

    摘要: A circuit configuration for controlling a major number of consumers (5) such as the electromagnetically operable multi-directional valves of an anti-lock control system (MWV1-MWVn) comprises a control unit (2, 3) whose output signals can be fed to the consumers (5) via amplifier stages (4). The individual amplifier stages (4; VS1-VSn) are designed as so-called “intelligent power drivers” and essentially consist of a power amplifier (18) with integrated electronic controls and monitors. The control unit (2, 3) and the amplifier stages (4; VS1-VSn) are interconnected to form a closed loop or chain. Data transfer is performed from a synchronous serial interface of the control unit (2, 3), via the individual amplifier stages (4; VS1-VSn) and back to a serial entry of the control unit (2, 3).

    摘要: A circuit arrangement for monitoring leakage currents of a circuit which includes a plurality of valve coils connected in parallel to a supply line and adapted to be connected to ground by way of individual switches, and wherein the supply line is connected by way of a main switch to the positive pole of the supply voltage source and, further, to a testing current source used as a test signal source, is designed such that prior to each closing of the main switch, with the individual switches still open, the testing current source is connected to the supply voltage source and thereby activated. The result is an increase of the voltage potential on the supply line. A comparator establishes the difference between the potentials on the supply line and the supply voltage. If the difference exceeds a threshold value, this indicates leakage current.
