Abstract (en)
[origin: WO2005038225A1] The invention relates to an internal combustion engine comprising a crankshaft, a camshaft and an adjusting device, which is used to adjust the phase position (PH) of the camshaft in relation to the crankshaft. The phase position (PH) is determined in accordance with a detected crankshaft angle (CRK) and a recorded camshaft angle (CAM). A filter coefficient (FF3) of a filter is determined in accordance with the amplitude (AMP) of an oscillation of the phase position (PH) and the modification (DELTA) of said phase position (PH). A filtered phase position (PH_FIL) of the determined phase position (PH) is calculated using the filter.
