Abstract
A method for switching between a degraded mode and a normal mode for determining the angular position of an internal combustion engine of a vehicle. The method includes the following steps, in a degraded mode: detecting the free space and the teeth of the toothed wheel of the crankshaft from the signal generated by the crankshaft sensor during the rotation of the crankshaft, determining the minimum rotation speed of each combustion top dead center of the crankshaft during a revolution of the crankshaft from the detected free space and the detected teeth, determining the angular positions of the crankshaft corresponding to the minimum determined rotation speeds, and switching to normal mode when, for each combustion top dead center, the difference between the determined angular position of the crankshaft and a reference angular position value is below a predetermined position threshold for at least one revolution of the crankshaft.
