Abstract
An ECM 2 performs an idle-stop operation on a vehicle internal combustion engine 4 in an idle operation state. The ECM 2 is supplied with power from a battery 3. The ECM 2 restarts the internal combustion engine 4 upon request by supplying power from the battery 3 to the starter motor 5. The ECM 2 is programmed to determine if the ECM 2 has experienced an unexpected restart during an engine start-up operation (S1, S2), and prevent the idle-stop operation from being executed on the internal combustion engine 4 when the determination is affirmative. Thus, starting failure of the internal combustion engine 4 from an operation-ceased state can be prevented without preventing the idle-stop operation from being executed excessively.
