Abstract:
A method for determining the angular position of an engine by a crankshaft sensor, having the following steps: production by the crankshaft sensor of a signal exhibiting a “revolution” event, determination of the revolution out of two revolutions, since a crankshaft makes two revolutions per engine cycle for a four-stroke engine, for each “no tooth” event potentially produced, a change in the direction of rotation of the engine is suspected, and an analysis step is performed which comprises: if, during an inverse window, a further “no tooth” event is produced, the change in direction of rotation is confirmed.

Claim (Index 1):
A method for determining the angular position of an engine by a crankshaft sensor comprising a crankshaft detector facing a crankshaft toothed wheel comprising a large number of regular teeth and a revolution marker, the crankshaft detector being able to produce a signal having a \u201ctooth\u201d event corresponding to an edge for each of said teeth, a \u201crevolution\u201d event for the revolution marker, and a \u201cno tooth\u201d event when two successive \u201ctooth\u201d events are abnormally separated, the method comprising:\n producing, by the crankshaft sensor, a signal having a \u201crevolution\u201d event, \n determination of the revolution out of two revolutions for a four-stroke engine, a crankshaft performing exactly two revolutions per cycle of the engine, in order to complete the determination of the angular position of the engine, wherein for each \u201cno tooth\u201d event possibly produced, a change in direction of rotation of the engine is suspected, and an analysis step is carried out comprising: \n if in an inverse window, at a distance from the current \u201cno tooth\u201d event equal to the distance between the preceding \u201crevolution\u201d event and the current \u201cno tooth\u201d event, toleranced by +/\u2212 a tolerance of teeth, a new \u201cno tooth\u201d event is produced, the change in direction of rotation is confirmed, and \n if in the inverse window no \u201cno tooth\u201d is produced, the change in direction of rotation is invalidated, each of the conditions being considered in its order of occurrence.
