METHOD AND DEVICE FOR DETECTING THE ANGULAR POSITION SIGNAL IN AN INTERNAL COMBUSTION ENGINE

摘要

Method for detecting a signal that represents the rotational movement of rotating part of a combustion engine and is detected using a rotational velocity sensor (11). A pressure sensor (12) measures the pressure in the combustion chamber. The method has the following steps: acquisition of the pressure signal, acquisition of the rotational movement signal, formation of a correction value (delta phi i) dependent on the pressure and rotation signals and determination of an angular position signal by combining the rotation signal with the correction value. The invention also relates to a corresponding device for implementation of the inventive method.
