Abstract:
An exact synchronization method for determining an angular position of an engine, modulo one engine cycle, by a crankshaft sensor and of at least one camshaft sensor. The method includes: estimating a continuous estimated interval assumed to contain the angular position, on receipt of a “marker” event, determining an angular position corresponding to each one of the possible occurrences of this “marker”, comparing the determined angular position with the estimated interval. If exactly one of the determined angular positions belongs to the estimated interval, then this angular position is the angular position of the engine. And an engine control method using such a method.

Claim (Index 1):
An exact synchronization method for determining an angular position of an engine, modulo one engine cycle, by a crankshaft sensor comprising a crankshaft detector facing a crankshaft toothed wheel, performing two revolutions per engine cycle, and comprising a large number of regular teeth and at least one marker, the crankshaft detector being able to produce a \u201ctooth\u201d event corresponding to each of said teeth, and a \u201cmarker\u201d event for a marker, and at least one camshaft sensor, each camshaft sensor comprising a camshaft detector facing a camshaft toothed wheel, performing one revolution per engine cycle, and comprising a small number of teeth, advantageously irregular, a camshaft detector being able to produce a \u201cstart of tooth\u201d event for each rising edge and/or an \u201cend of tooth\u201d event for each falling edge, the method comprising:\n estimating a continuous estimated interval assumed to contain the angular position, \n on receipt of a \u201cmarker\u201d event, determining an angular position corresponding to each one of the possible occurrences of this marker, and \n comparing the determined angular positions with the estimated interval:\n if none of the determined angular positions belongs to the estimated interval, or if more than one of the determined angular positions belongs to the estimated interval, then exact synchronization is not achieved, \n if exactly one of the determined angular positions belongs to the estimated interval (IP), then this angular position is the angular position of the engine, and exact synchronization is achieved.
