ABSTRACT:
Device for determining the position of an engine includes:a sensor that has a rotary part and a fixed part, whereby said fixed part comprises:elements (for generating a first signal based on the position of the rotary part relative to the fixed part),Second elements for generating a second phase-shifted signal relative to the first signal,elements for comparing the value of the second signal to a reference value,elements for detecting at least one characteristic event on the first signal, for generating a third signal of binary type, and for alternating the binary signal from a first value to a second after detection of at least one of the characteristic events if the result of the comparison is positive,engine control elements that include members for detecting the alternations of third signal and a counter.
