1. A control device for a vehicle including an engine, a motor coupled to a power transmission path between the engine and drive wheels so as to be able to transmit power, a clutch that is provided between the engine and the motor in the power transmission path and a control state of which is switchable by controlling a hydraulic clutch actuator, and a hydraulic control circuit system that supplies an adjusted hydraulic pressure to the clutch actuator, the control device comprising an electronic control unit configured to:
output a first command value to the hydraulic control circuit system and then output a second command value to the hydraulic control circuit system during a transition in which the control state of the clutch is switched from a disengaged state to an engaged state when starting the engine, the second command value being a command value for supplying the hydraulic pressure to the clutch actuator such that the clutch transmits cranking torque for raising a rotational speed of the engine, and the first command value being a command value for supplying the hydraulic pressure to the clutch actuator so as to reduce a pack clearance in the clutch;
perform first control in which the motor outputs the cranking torque, and second control in which the engine starts operation, when starting the engine; and
when the vehicle is in a predetermined state in which a required hydraulic pressure is not secured stably when starting the engine, start output of the first command value when the vehicle is not in the predetermined state, the required hydraulic pressure being a hydraulic pressure supplied from the hydraulic control circuit system to the clutch actuator and required to switch the control state of the clutch.
