<p><P>PROBLEM TO BE SOLVED: To precisely conduct an abnormality diagnosis of an AC generator when controlling power generation by arranging the AC generator which can freely change a power generation amount by using an ECM control signal of a control means, and by arranging a current detection means which can detect a load current value of an electric load, in a power generation control device of the AC generator. <P>SOLUTION: In this power generation control device, a control means comprises: a warm-up state estimation part which estimates the warm-up state of the AC generator; a magnetic field current control part which controls a magnetic field current of the AC generator by using an external input signal value which is set according to the warm-up state of the AC generator estimated by the warm-up state estimation means when a load current value detected by the current detection means is larger than a load current set value; and a failure diagnosis mode part which compares a battery voltage value and a set voltage value (S8), and determines whether the AC generator is failed or not. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
