| Zusammenfassung: | 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. |
