摘要： 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.

摘要： A device and method are provided for the redundant control of a power controlled device (R). The redundant control device comprises two programmable controllers (A.sub.1, A.sub.2) adapted for elaborating a control order. These two programmable controllers (A.sub.1, A.sub.2) are equipped with two respective logic circuits designed so as to apply to two outputs (s.sub.1, s.sub.2) two logic signals (S.sub.1, S.sub.2) whose combination using the EXCLUSIVE OR function is the image of the control order. The power device (R) is then controlled by a control member (O) connected by its two inputs, to said two outputs (s.sub.1, s.sub.2) and performing the logic EXCLUSIVE OR function of the signals (S.sub.1, S.sub.2) delivered by these two outputs. With this device, independently of the breakdown state of one of the two control circuits, the state of the controlled device always corresponds to the control order.
