Abstract

A control apparatus of an electric water pump (3) of the present invention is configured by an engine control unit (2) on a side of an engine and an electric water pump in a cooling water circulating circuit of the engine. The engine control unit (2) transmits signals of a measured water temperature and a target water temperature of the engine, and the electric water pump (3) includes a drive control unit (33) for executing control of adjusting a flow rate of the water pump on the basis of the signals of the measured water temperature and the target water temperature.
