<p>In a control device of an a.c. generator for a vehicle which is designed in such a way that for a first time right after an engine having been started, an output of the a.c. generator is suppressed to a minimum value, and for a second time following the first time, the output of the a.c. generator is gradually increased from the minimum value up to a maximum value to stabilize the revolution of the engine, the invention is intended to shorten a period of time required to suppress the output of the generator at high temperatures to thereby prevent a reduction in the charging performance of a battery. At high temperatures, a time interval of a timer 402, to which the first period of time is set, and a discharging time constant of a capacitor 407, which defines the second period of time ,are both shortened on the basis of an output a of a temperature sensor 410. At high temperatures, a detection threshold for a revolution detector 401, on the basis of which the start of the engine is detected, is set to a low level to shorten an initial excitation period of the generator. <IMAGE></p> |
