Internal combustion engine control device synchronization method for use in motor vehicle, involves determining relative angular position of shaft with respect to shaft of engine by evaluation of sound events produced by engine

摘要

The method involves determining a relative angular position of a shaft with respect to another shaft of an internal combustion engine by an evaluation of sound events (12, 13) produced by the engine. A control device is synchronized based on the determined relative angular position, and the sound events produced by the engine are received by a sound sensor i.e. knocking sensor (10) arranged on the internal combustion engine. The sound events are assigned to operational events of the engine. Independent claims are also included for the following: (1) a device for performing synchronization of a control device of an internal combustion engine (2) a computer program with a program code for performing a method for synchronization of a control device of an internal combustion engine.
