<p><P>PROBLEM TO BE SOLVED: To provide a technique capable of raising the voltage of a battery by detecting the voltage drop of the battery even after a microcomputer is reset. <P>SOLUTION: In this idling stop device 1, the microcomputer 2 is reset when the voltage of the battery 51 is lowered and the voltage VCC of the power supply of the microcomputer 2 is less than the minimum operating voltage Vt of the microcomputer 2. The information of the voltage drop is stored in a storage part 3. Consequently, after the reset, the microcomputer 2 can detect that the voltage of the battery 51 is lowered based on the information of the voltage drop, and then can raise the voltage of the battery 51 by increasing the power generation amount of an alternator 52 for charging the battery 51. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
