Abstract:
A method for determining the angular position of an engine by a crankshaft sensor and a camshaft sensor. The method includes production by the crankshaft sensor of a revolution event, determination of the angular position of the camshaft by identifying the start-of-tooth and end-of-tooth events following the revolution event, in rapid mode, over at most one revolution of the crankshaft, if a no tooth event occurs after the revolution event and if the determination of the angular position of the camshaft fails, the method continues with a step of determining the angular position of the camshaft by identification, in slow mode, over at least two crankshaft revolutions.

Claim (Index 1):
A method for determining an angular position of an engine by way of a crankshaft sensor comprising &crankshaft detector facing a crankshaft toothed wheel, performing two revolutions per engine cycle, and comprising a large number of regular teeth and a revolution marker, the crankshaft detector being able to produce a \u2018tooth\u2019 event corresponding to an edge for each of said teeth, a \u2018revolution\u2019 event for the revolution marker, and a \u2018missing tooth\u2019 event when two successive \u2018tooth\u2019 events are abnormally far apart, and of a camshaft sensor comprising a camshaft detector facing a camshaft toothed wheel, performing one revolution per engine cycle, and comprising a small number of irregular teeth, the camshaft detector being able to produce a \u2018tooth start\u2019 event for each rising edge and a \u2018tooth end\u2019 event for each falling edge, the method comprising:\n producing a \u2018revolution\u2019 event by the crankshaft sensor, \n determining the angular position of the camshaft by identifying the \u2018tooth start\u2019 and \u2018tooth end\u2019 events following said \u2018revolution\u2019 event, in a fast mode, over at most one crankshaft revolution, wherein if a \u2018missing tooth\u2019 event is produced after the \u2018revolution\u2019 event and if the determination of the angular position of the camshaft fails, the method continues with a step of: \n determining the angular position of the camshaft by identifying the \u2018tooth start\u2019 and \u2018tooth end\u2019 events, in a slow mode, over at least two crankshaft revolutions.
