ABSTRACT:
In a method for detecting reverse rotation when starting an internal combustion engine having a sensor disk which is coupled to a crankshaft of the engine, the sensor disk having a marking via an alternating arrangement of teeth and tooth spaces, and a first sensor and a second sensor each capable of generating an electric signal which may assume at least two signal levels, being associated with the sensor disk, one of the signal levels being associated with a tooth and the other signal level with a tooth space, a rising or falling signal edge of the one signal and the signal level of the other signal being used for determining the direction of rotation and increment of the angle of rotation of the crankshaft, the start characteristics are improved by determining the direction of rotation during the start of the engine as early as at the first signal edge.
