Control device and control method of vehicle

A control device of a vehicle provided with a power source and a power transfer device, the control device comprising:

• a driving control unit configured to set a target traveling state, and perform automatic driving control by automatically performing acceleration and deceleration based on the target traveling state;
• and
• a learning control unit configured to correct, by learning control, an amount of operation associated with control of the vehicle for each of a plurality of learning regions according to a driving state of the vehicle,
• wherein the driving control unit is configured to, while performing the automatic driving control, preferentially select traveling in the driving state of the vehicle corresponding to unconverged regions between:
• (i) the traveling in the driving state of the vehicle corresponding to the unconverged regions in which the correction of the amount of operation is not converged among the plurality of learning regions;
• and
• (ii) traveling in the driving state of the vehicle corresponding to converged regions in which the correction of the amount of operation is converged among the plurality of learning regions.
