Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electronic controller which is designed to obtain the actual value of a voltage dividing ratio of a voltage dividing circuit 70. SOLUTION: In an engine ECU40, each time a power source voltage Vdc reaches the maximum value Vset in the output range of a DC/DC power circuit 50, a power source control circuit 83 outputs a high level signal as a power source voltage signal SFLG. Meantime, each time a high level signal is inputted as the power source voltage signal SFLG from the power control circuit 83, a microcomputer 93 acquires a digital signal outputted from an A/D converter 91. Also, on each such acquisition, the actual value kb' (=Va/Vset) of the voltage dividing ratio is determined based on the digital signal. COPYRIGHT: (C)2011,JPO&INPIT
