    摘要: A method is described for determining the angle-of-rotation position (φ) of a shaft of an internal combustion engine, in particular a crank angle (φ) of a crankshaft, information at least about incremental angles of rotation (Δφ) of the shaft and running times (T) for each incremental angle of rotation (Δφ) being detected on the basis of signals which indicate the rotation of the shaft and are spaced with intervals between them, and stored at least temporarily the instantaneous angle-of-rotation position (φ) being determined in the period of time between two signals by extrapolation of the angle-of-rotation position (φ) thus detected, taking into account at least one angular velocity ({overscore (ω)}) and/or change in angular velocity (Δ{overscore (ω)}) extrapolated from the stored information. In addition, a corresponding device is also described.

    摘要: A method for protecting an automotive generator from overheating, in which a predefined limiting characteristic curve, related to a base temperature and describing a maximally allowed excitation current value, is shifted as a function of a calculated temperature, a static offset is ascertained in a first step and a dynamic offset is ascertained in a second step during ascertainment of the calculated temperature, the static offset is ascertained as a function of the excitation current and the dynamic offset is ascertained as a derivation of the excitation current over time.
