PROBLEM TO BE SOLVED: To prevent that the calculation of the internal resistance of a power accumulation device whose use frequency is lower is not performed for a long period of time, in a vehicle having two power accumulation devices.SOLUTION: When a state determination part 221 determines that a water temperature detected by a water temperature sensor 204 is higher than a reference temperature To, a start control part 222 drives a B-ISG 2 by power of a capacitor 4, and starts an engine 1 by the B-ISG 2. On the other hand, when a time elapses for a prescribed time TA or longer after a calculation part 223 calculates an internal resistance of a battery 3 last time, the start control part 222 drives a gear drive-type starter 7 by power of the battery 3 even if the water temperature is higher than the reference water temperature To.SELECTED DRAWING: Figure 2 |
