摘要:
The invention relates to a method for protecting a motor vehicle generator from overheating, wherein a specified limiting characteristic curve, relating to a base temperature and describing a maximally allowable exciting current value, is shifted in dependence on a computed temperature, a static offset is determined in a first step and a dynamic offset is determined in a second step upon determination of the computed temperature, the static offset is determined in dependence on the exciting current and the dynamic offset is determined as a derivation of the exciting current over time.
