Abstract: Method for correcting an angle error of an absolute-angle detector that detects the angular position of a first shaft whose rotary movement is linked to a second shaft. The angular position of second shaft is first detected during at least one complete revolution of first shaft; the corresponding angular position of first shaft is derived from this value; the corresponding output value of absolute-angle detector is compared to the corresponding angular position of first shaft, and the difference formed by this comparison is stored. The corresponding output value of absolute-angle detector is then corrected by the stored value.

Abstract: Method and arrangement for operating an internal combustion engine (10) which is operable in several operating modes, especially an internal combustion engine (10) having direct injection or intake manifold injection and having a control apparatus (11). The control apparatus (11), that is, its software has a plurality of functions (12) and a scheduler (13) for activating the functions (12). The executability of the functions (12) is determined in dependence upon the operating-mode dependent and operating-mode independent conditions and, with the aid of a bridging signal, the determination of the operating-mode dependent conditions can be disabled.
