PROBLEM TO BE SOLVED: To suppress an increase in charging and discharging power of a battery mounted on a vehicle. SOLUTION: Based on the information detected by various sensors (for example, a speed of the vehicle, a stepping amount of the accelerator pedal, a stepping amount of the brake pedal, etc.), a driving behavior that the operator is going to do is estimated. When the estimated driving behavior is deceleration, the charging power of a battery 12 may increase since power generation by a motor 11 is increased by a regeneration brake at the time of deceleration, and so an increase in charging power of the battery 12 is suppressed by increasing the power consumption of an electric compressor 15 for air conditioner. On the other hand, when the estimated driving behavior is acceleration, the discharging power of the battery 12 may increase since the power generation by the motor 11 decreases, and so an increase in the discharging power of the battery 12 is suppressed by reducing the power consumption of the electric compressor 15. By this method, the frequency of an increase in charging and discharging power of the battery 12 is reduced to reduce the charging and discharging loss of the battery 12.
