The method involves determining speed of heat engine and an alternator (76). Speed rates of the engine and the alternator are compared (78). Slippage of an accessory belt is detected (80) based on a comparison result. The speed determining step, the comparison step and the slippage detection step are performed at the time of heat engine shutdown preparing phase (72) during which injection of fuel in combustion chambers is maintained while closing entry of airflow in the chambers. Shut down of the heat engine is not controlled when the slippage of the belt is detected. Independent claims are also included for the following: (1) an information recording medium comprising a set of instructions to execute a method for detecting slippage of an accessory belt (2) an assembly for detecting slippage of an accessory belt, comprising sensors.
