    摘要: A circuit to monitor a short circuit (or a line interruption) in an inductive circuit which is connected to a signal-processing circuit through a high-ohmic filter circuit. The monitoring circuit is formed as a component part of or as an additional element to the signal-processing circuit and initiates a test cycle to determine the inductance of the circuit to be monitored when, for example, the ignition of an automotive vehicle is turned on when the inductive circuit is used in the circuitry for sensing wheel rotation behavior of an automotive vehicle.

    摘要: A circuit for triggering warning lamps including a self-conductive transistor circuit with a triggering circuit connected to the supply voltages. The triggering circuit keeps the transistor circuit blocked if the supply voltages are proper. If voltage fails, the transistors of the self-conductive transistor circuit open a current path from the warning lamp terminal to the control terminal of the power driver which results in switching on of the power driver and, thus, of the warning lamp.

    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: 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 arrangement for monitoring a control circuit, which has a driver transistor with an inductive load and a second transistor in a circuit branch parallel to the inductive load, includes an additional, external current measuring device. A switching element, in particular a transistor and an ohmic measuring resistor, is provided parallel to the driver transistor. At a test instant, the current flowing through the inductive load is diverted to the measuring device and induces a voltage at the measuring resistor which is indicative of the status of the control circuit.

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: To monitor a data processing circuit which includes two (or a plurality of) microprocessors or other data processing systems which are mounted on a joint chip and connected by data lines, the microprocessors jointly produce data words which form a data word sequence and are transmitted to a monitoring circuit at predetermined times. The monitoring circuit is arranged on a separate chip. The data words of the data word sequence are checked by the monitoring circuit with respect to the contents and time of appearance of the individual data words. It is favorable to make up the individual data words of partwords which are produced according to different algorithms.
