A control method of a car power generation control system that controls power generation of an alternator is composed of the following steps. (i) The power generation of the alternator is controlled to be restricted at the early stages of an engine start. (ii) The point in time when an engine threshold rpm value is determined more than a predetermined threshold rpm value by judging whether the engine rpm value among the information which is monitored outside is more than a predetermined threshold rpm value or not is decided as a first point in time, and a delay time corresponding to the temperature of the monitored car information is calculated. (iii) Whether the calculated delay time reaches a passed second point in time or not is determined from the first point in time. (iv) The power generation of the alternator is controlled to start in case the delay time reaches the second point in time. [Reference numerals] (10) Engine; (46) Vehicle electronic unit
