摘要： A diagnostic device for a sensor for measuring the position of a motor-vehicle drive shaft. The sensor includes a first wired communication link and a second wired communication link, via which wired communication links the sensor sends the signal, and being characterized by an average reference voltage. The diagnostic device for a sensor being intended to be electrically connected between the first wired communication link and the second wired communication link and being configured to: a) receive a first voltage value corresponding to the average voltage in the first wired communication link and a second voltage value corresponding to the average voltage in the second wired communication link; b) detect a short circuit on the first wired communication link; or c) detect a short circuit on the second wired communication link.

摘要： A method for automatically detecting a sensor coupled to an electronic computer, including a second step, consisting of passing to a third step when the electronic computer is activated, the third step, consisting of comparing a voltage generated by the sensor coupled to the terminals of the electronic computer with a reference voltage, in the event that the result of the comparison is positive, then passing to a fourth step, and in the event that the result of the comparison is negative, passing to a fifth step, the fourth step, consisting of selecting an impedance matched to the coupling of the voltage-source sensor to the terminals of the electronic computer.

摘要： The aim of the present invention is a method for synchronizing an engine comprising at least one movable piston of a four-stroke internal combustion engine, said method comprising a first step (e1) involving initializing a second memory space, a second step (e2) involving waiting for an edge on a fourth signal (CAM_TOT), a fourth step (e4) involving testing the value of a counter (CPT), an eighth step (e8) involving selecting the theoretical angular positions of the slots of the second signal (CAM_IN) relative to the edges of a first signal (CRK) and of the slots of a third signal (CAM_EX) relative to the edges of the first signal (CRK).
