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

摘要

The invention relates to a method for detecting an angular position signal which represents the rotational movement of a rotating element of an internal combustion engine, whereby said internal combustion engine has at least one combustion chamber. A speed sensor emits a speed measuring signal which represents the rotational movement of a sensor wheel that is linked with the rotating element. At least one pressure sensor emits a pressure signal which represents the pressure in a combustion chamber. The inventive method comprises the following steps: detecting the pressure signal; detecting the speed measuring signal; producing a correction variable which depends at least on the detected pressure signal and speed measuring signal, and detecting the angular position signal by linking the detected speed measuring signal with the correction variable. The inventive method and device allow to identify and compensate any sensor wheel errors by a common evaluation of the speed signal and the combustion chamber pressure of one or more indicated cylinders.
