Abstract
A method for detecting the physical stoppage of an internal combustion engine including a crankshaft that drives a toothed wheel having a plurality of teeth, each tooth corresponding to different angular positions of the crankshaft, a sensor positioned next to the toothed wheel generates a signal characteristic of the passage of a tooth. The method detects a tooth from the signal generated by the sensor, identifies the tooth detected, triggers a timeout, and detects stoppage of the engine if the passage of a tooth adjacent to the tooth detected has not been detected before the end of the timeout. The value of the timeout is dependent on the tooth identified, and including: determining crankshaft angular position depending on the tooth identified, the value of the timeout dependent on the angular position of the crankshaft, determining the preferential stopping positions of the crankshaft and assigning a first timeout value for the preferential stopping positions and assigning at least a second value for the other positions of the crankshaft. The first timeout value being less than the second timeout value.
