摘要： A control unit for an electric oil pump of the present invention includes: a one-way valve that permits circulation of operating fluid from the electric oil pump to the friction engagement device and blocks circulation in the opposite direction; an accumulator that is connected to a fluid supply path joining the one-way valve to the friction engagement device and accumulates hydraulic pressure required for operating the friction engagement device; a hydraulic pressure measuring device that measures hydraulic pressure inside the fluid supply path; a vehicle speed measuring device that measures a vehicle speed of the vehicle; and a pressure setting device that sets a first predetermined pressure based on the vehicle speed measured by the vehicle speed measuring device.
