PROBLEM TO BE SOLVED: To increase chances of executing idling stop effective for lower fuel consumption even in a low battery temperature state.SOLUTION: A battery charge rate SOC is stored in a storage device 57 for each battery temperature Tv as an idling stop prohibition threshold SOC2 for prohibiting execution of an idling stop control. A controller 50 prohibits execution of the idling stop control if the battery charge rate SOC falls below the idling stop prohibition threshold SOC2 when idling stop is to be executed. In this way, the idling stop prohibition threshold SOC2 for prohibiting execution of the idling stop control is the battery temperature Tv in a low temperature range and set lower than the battery temperature Tv in a high temperature range. |
