Abstract

An idling stop device is mounted on a vehicle. A microcomputer has an idling stop function of automatically stopping an engine of the vehicle when a predetermined stop condition is established and automatically starting the engine when a predetermined start condition is established during the stopping of the engine. A detecting unit detects that a power voltage of the microcomputer, which is obtained by dropping a voltage of a battery of the vehicle is lower than a minimal operation voltage of the microcomputer. A storage unit stores voltage decrease information irrespective of a state of the microcomputer if the power voltage is lower than the minimal operation voltage. A power control unit stops supply of power to some of electrical loads to which power is supplied from the battery when the engine is started, if the voltage decrease information is stored in the storage unit.
