ABSTRACT:
A device for detecting and discriminating operating faults in an electrical power supply circuit comprises a control circuit integrating a power transistor controlling the electric supply of a load, detectors and a logic circuit connected to a computer by two lines, an input/output control line and a selection line. The computer selectively and successively controls, by specific combinations of logic signals applied on the input/output control line and the selection line, several logic sub-circuits for the detection and identification of operating faults in the power supply circuit of the load, such faults being permanent control, short circuit and open circuit, the circuit in return imposing on the input/output control line logic levels representative of the presence of absence of operating faults, during the time intervals in which the computer is configured to read these levels. For a plurality of the power supply circuits, the selection line is common to all such power supply circuits. Application may be made to the diagnosis to the operating states of electromechanical valves forming part of a wheel anti-locking device on a vehicle.
