摘要：
The ECU includes: a stop control portion controlling an electric water pump to stop, when an engine provided with the electric water pump pressure-feeding a coolant is warmed up; a first drive control portion controlling the electric water pump to drive for a predetermined period at least before the stop control portion performs a control, when a coolant temperature thw in starting the engine is equal to or higher than a predetermined value α. The electric water pump corresponds to a variable water pump capable of changing the flow rate of the coolant.
