Abstract: A method for determining a signal offset between a crankshaft angle signal and a combustion chamber pressure signal includes: measuring the combustion chamber pressure signal; shifting an alignment of the measured combustion chamber pressure signal with respect to the crankshaft angle signal by a plurality of respective offset angles to generate a plurality of offset combustion chamber pressure signals; reconstructing the offset combustion chamber pressure signals using a plurality of predetermined inherent pressure curves to generate reconstructed combustion chamber pressure signals; determining reconstruction errors of the reconstructed combustion chamber pressure signals as a function of differences between the offset combustion chamber pressure signals and the reconstructed combustion chamber pressure signals; and determining the signal offset between the crankshaft angle signal and the combustion chamber pressure signal as a one of the plurality of offset angles producing the reconstruction error having the lowest value.

Abstract: The invention relates to a method for determining correction information for an electric machine (7) which has a stator winding and a rotatably mounted rotor having multiple pole pairs, wherein a reference rotational angle (φRef) of the rotor is selected; an actual variable influenced by a rotation of the rotor is determined and is monitored for interference waves (SW); when an interference wave (SW) is detected, an interference-wave correction instruction which is based on the reference rotational angle (φRef) and is intended for compensating for the detected interference wave (SW), and a reference feature of the interference wave (SW) based on the reference rotational angle (φRef) are determined; a reference rotational angle value of the reference rotational angle (φRef) is determined on the basis of a rotational angle interval (Δφel) covered during an electrical revolution of the rotor; and the determined interference-wave correction instruction, the determined reference feature and the determined reference rotational angle value are assigned to one another and stored as correction information.

Abstract: A method for determining a signal offset between a crankshaft angle signal and a combustion chamber pressure signal in an internal combustion engine, in which an instantaneously measured combustion chamber pressure profile is compared to a calculated, modeled combustion chamber pressure profile. In a method in which the correction values of the signal offset may be ascertained in any operating state of the internal combustion engine, the instantaneously measured combustion chamber pressure profile is shifted with respect to the calculated, modeled combustion chamber pressure profile along a crankshaft angle for generating an artificial signal offset, and a reconstruction quality is determined from this shifted combustion chamber pressure profile in that, from the artificial signal offset along the crankshaft angle of the shifted instantaneously measured combustion chamber pressure profile, a reconstruction error is ascertained as a measure of the effective signal offset between the crankshaft angle signal and the combustion chamber pressure signal.
