CIRCUITRY FOR MONITORING AN INDUCTIVE CIRCUIT

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.
