摘要： A process is disclosed for monitoring a final stage component (1, 1') to which a plurality of inductive loads (L1, L2, Ln) are connected. The current that flows through these inductive loads is regulated by cyclically driving the end stages (8). The current generated in the locking phases of the end stages by the inductively stored energy is partially or temporarily led through a common current measurement device (RRCS, 4) and evaluated for testing the final stages, including the inductive loads (L1, L2, Ln).

摘要： The invention concerns circuitry designed to recognize a short-circuit (or a line break) in an inductive circuit (1) connected via a high-resistance filter circuit (3) to a signal-processing circuit (2). The circuitry includes a monitoring circuit (4, 4') which is designed as part of or as an additional element to the signal-processing circuit (2) and which, when the ignition is switched on, initiates a test cycle designed to determine the inductance of the circuit (1) being monitored.

摘要： For evaluating the output signal in the form of a binary current signal (IS) from an active sensor (1), a circuit is proposed in which a proportional current is derived from the sensor current (IS) with the aid of a current balancing circuit (2, 2'), and the current (I1) resulting from current balancing is drawn off from a stabilised voltage source (UK) via an ohmic resistor (R1), thereby generating a binary voltage signal (V1) which is applied to a flipflop (3) comparing the voltage signal (V1) with a reference voltage (UBez) composed of a reference voltage (URef) and a hysteresis voltage. The switching threshold of the flipflop (3) is varied or adjusted in accordance with the actual sensor current (IS), leakage currents, etc.

摘要： In order to monitor a data processing circuit containing two (or more) microprocessors (MP1, MP2) on a shared chip and interconnected by data lines (1), said microprocessors generate data in common which form a data word sequence and are transmitted to a monitoring circuit (4) at predetermined times. The monitoring circuit (4) is on a separate chip (IC2). The data words of the data word sequence are monitored by the monitoring circuit according to the content and time of occurrence of the individual data words. It is an advantage to compose the individual data words of partwords generated by different algorithms.
