Abstract

Abstract A control device for an alternating current generator of a vehicle, having a storage battery (4) which is charged by a rectified output of the alternating current generator. (1), a current detecting resistance (304) wherein current substantially equal to a field current flowing in a field coil (12) of the alternating current generator, flows and which has a temperature coefficient, voltage setting means (305,306,319) for setting a reference voltage for comparison, and a comparator (307) for comparing a both terminal potential difference of the current detecting resistance (304) with the reference voltage for comparison, which restricts the field current of the alternating current generator by interrupting the field current based on a comparison result of the comparator, characterized in that the voltage setting means (319) changes the reference voltage for comparison in accordance with temperature to compensate a temperature gradient of the both terminal potential difference of the current detecting resistance (304).
