Zusammenfassung:	PROBLEM TO BE SOLVED: To highly accurately control an electric oil pump on the basis of a detection value of an oil temperature while suppressing an increase in cost and deterioration of layout property.SOLUTION: A main computer (first unit) 5 inputs an output of an oil temperature sensor 6 and outputs a detection value of an oil temperature to a pump driving computer (second unit) 4 via a first signal line SL for a stop period of an electric oil pump 2. The main computer 5 outputs a target value of the electric oil pump 2 in place of the detection value of the oil temperature to the pump driving computer 4 via the first signal line SL for an operation period of the electric oil pump 2. The pump driving computer 4 outputs operation amount of the electric oil pump 2 to a drive circuit 3 on the basis of the target value and the oil temperature.
