In the case of a process for recognizing the rotating direction of an internal-combustion engine using a crankshaft angle sensor, a camshaft angle sensor and an electronic internal-combustion engine control unit which processes the signals of these two sensors, a certain first crankshaft position, which can be sensed by the crankshaft angle sensor and which exists in the case of a reversely rotating internal-combustion engine, is assigned to a certain camshaft position which can be sensed by the camshaft angle sensor. A certain second crankshaft position, which exists in the case of a forward-rotating internal-combustion engine, is assigned to the same camshaft position. These assignments are stored in the internal-combustion engine control unit so that they can be queried to recognize the rotational direction of the engine.
