Control device for vehicle
7 Nov 23
An electronic control unit is 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; 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.
