1. A method for compensating a reference measurement comprising a measurement of angular position α

  • and a measurement of time T1 that are simultaneous at a moment in time t1, for an angular position sensor of the type comprising a toothed wheel, characterized in that it comprises the following steps;

    determination of a first measurement α

    of the angular position at the moment in time t1 when a reference measurement is desired,triggering of a software acquisition function, taking into account said function resulting in a time delay Δ

    t,substantially simultaneous acquisitions of a second measurement α



    of the angular position and of a measurement T2 of the time by software acquisition at the time t2,estimation of a time error Δ

    T,calculation of the measurement of time, T1=T2

    Δ

    T.
