Abstract
There is provided a clutch control device which includes an electric oil pump, a clutch unit, and a pressure measurement unit, and which controls an operation of the electric oil pump so as to change a transmission state of the clutch unit. The device includes a pressure control valve that is located between an oil passage for connecting the electric oil pump and the clutch unit to each other and an oil pan for storing an unpressurized hydraulic oil, and that discharges the pressurized hydraulic oil from the oil passage to the oil pan, when pressure of the hydraulic oil exceeds valve opening pressure, and a pump drive control unit that controls hydraulic pressure by driving the electric oil pump, based on target pressure indicated by a change command of the transmission state of the clutch unit and the hydraulic pressure measured by the pressure measurement unit.
