Abstract
A control device for a variable-capacity oil pump provided in an engine using alcohol-containing fuel includes an electronic control unit. The electronic control unit is configured to: (i) estimate an alcohol concentration in oil of the engine, and (ii) correct a capacity of the oil pump to be increased in a correction condition as compared with a case where the correction condition is not established when the correction condition is established. The correction condition is that an estimated alcohol concentration is a predetermined concentration or more and a temperature of the oil is a predetermined temperature or more.
