<p><P>PROBLEM TO BE SOLVED: To provide technology capable of preventing large reduction in a battery voltage by grasping reduction of the battery voltage even after resetting a microcomputer. <P>SOLUTION: In the idling stop device 1, when the voltage of the battery 51 is reduced and a voltage VCC of a power source of the microcomputer 2 is reduced less than the lowest action voltage Vt of the microcomputer 2, the microcomputer 2 is reset. Whereas, the voltage reduction information is stored in a memory part 3. Then, the microcomputer 2 after resetting can grasp that the voltage of the battery 51 is reduced based on the voltage reduction information. After that, the microcomputer 2 stops feeding of the electric power to an electric load part 58 when an engine 57 is started. Thereby, large reduction of the voltage of the battery can be prevented when the engine 57 is started. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
