Control device for vehicle

A control device for a vehicle, the vehicle comprising:

• an internal combustion engine;
• an electric motor connected to a power transmission path between the internal combustion engine and a drive wheel so as to be able to transmit power;
• a connection and disconnection clutch that is provided in the power transmission path and disconnects connection between the internal combustion engine and the electric motor by being in a released state;
• a starter for starting the internal combustion engine;
• and
• a hydraulic control mechanism for controlling a hydraulic pressure supplied to the connection and disconnection clutch, wherein the control device of the vehicle is configured to
• perform slip control in which the connection and disconnection clutch is engaged by supplying an instruction hydraulic pressure for engaging the connection and disconnection clutch by the hydraulic control mechanism as an instruction hydraulic pressure for maintaining a speed of the internal combustion engine to a speed higher than a lower limit speed for avoiding stop of the internal combustion engine, after the internal combustion engine is started by the starter, and
• perform engagement completion control in which the instruction hydraulic pressure for engaging the connection and disconnection clutch by the hydraulic control mechanism is increased from the instruction hydraulic pressure in the slip control to an instruction hydraulic pressure in which engagement of the connection and disconnection clutch is completed when a difference between the speed of the internal combustion engine and a speed of the electric motor becomes smaller than a preset threshold value.
