Abstract

See full text

Disclosed is a method for synchronizing a combustion engine of a motor vehicle, including the steps of detection of the reference position of a first toothed wheel during a rotation of the crankshaft from the measurements sent by a first measuring sensor, detection of rising and falling edges of the teeth of a second toothed wheel during a concomitant rotation of the camshaft from the measurements sent by a second measuring sensor, identification of the detected edges with a first tolerance threshold on the angular position of the camshaft from recorded positions of the edges to synchronize the engine, the recorded positions being predetermined by learning from theoretical positions with a second tolerance threshold on the angular position of the camshaft, the first tolerance threshold being less than the second tolerance threshold, and synchronization of the engine from the identified edges of the teeth of the second toothed wheel.
