| 摘要 |
The present invention relates to a mechanical counter for the distance covered by a vehicle, characterised in that it comprises: a stepper motor having displacement cycles each formed by several stable positions and a means (200) for controlling the stepper motor which comprises correction means designed to automatically increment the advance pulses applied to the stepper motor, on each initialisation of the supply of the control means (200), by a number which is a function of the error resulting from the offset between the actual position of the rotor of the stepper motor during the cut-off of the supply of the control means and the original stable position of a displacement cycle. <IMAGE>
