Abstract
Disclosed is a method for detecting physical stoppage of an internal combustion engine, including: at least four cylinders, a set of cylinder pressure sensors, configured such that, over the course of a combustion cycle of the engine, there is at least one cylinder in the compression or expansion phase whose pressure is measured by a pressure sensor of the set, the method including the following steps: measuring the pressure in a cylinder in the compression or expansion phase, calculating, from the pressure measured in the cylinder, a ratio between a pressure variation in the cylinder and the pressure in the cylinder, and detecting a physical stoppage of the engine if the measured pressure is decreasing and if the calculated ratio is constant.
