Abstract: PROBLEM TO BE SOLVED: To solve a problem wherein it is difficult to accurately judge presence or absence of execution of an automatic stop process of an internal combustion engine provided with initial rotation by a starter using an in-vehicle battery as a power supply. SOLUTION: A voltage of the battery is lowered by stopping the internal combustion engine by an idle stop process with respect to before stopping the internal combustion engine in stopping of a vehicle. Then by automatically starting the internal combustion engine, the battery voltage is largely dropped further from a voltage Vbr for just a voltage drop amount ΔVst. At this time, if it is predicted that a minimum voltage Vmin will become a threshold voltage Vth or more, idle stop is allowed by predicting the voltage Vbr and the voltage drop amount ΔVst before the idle stop process.
