| 摘要 |
<p>The invention relates to a system for detecting a longitudinal movement threshold and for determining the rotational speed of a cylindrical element translating along the central axis thereof and rotating about said axis, characterized in that it includes a single sensor (13) connected to a means for acquiring and processing the signal, and a target (14) arranged on the outer surface of the cylindrical element and capable of interacting with the sensor (13) so as to produce said signal, said target (14) comprising a first area (20) and a second area (21) that extend around the element, the second area (21) being contiguous with the first area (20), and in that the first area (20) is intended for determining the rotational speed of the element, and both areas are intended for detecting the movement threshold. The invention also relates to a starter including such a system.</p> |
