Abstract (en)
[origin: WO2005124134A1] Synchronization of the angle position of the crankshaft of a motor vehicle with the internal clock of a motor control device (110) is often imprecise and complicated and is often fraught with difficulties, particularly with regard to the detection and processing of external sensor signals. The invention relates to a motor control device (110) wherein the angle position of the crankshaft is initially detected and converted into an electronic trigger signal (136) in a trigger converter (114). The electronic trigger signal (136) controls detection and analog-digital conversion of an analog signal, particularly an analog sensor signal. Control occurs in such a way that data can only be detected when a specific trigger signal is present or that data can only be continuously detected and processed when a specific trigger signal is present.
