Control device and control method of vehicle
While automatic driving control is being performed, traveling in a driving state of a vehicle corresponding to an unconverged region (including an unperformed region and a performed region) is preferentially selected between the traveling in the driving state of the vehicle corresponding to the unconverged region, and traveling in the driving state of the vehicle corresponding to a converged region. As such, learning control that corrects an amount of operation associated with control of the vehicle is performed more easily throughout the entire learning regions regardless of a usage state of the vehicle by a driver. Therefore, it is possible to achieve an appropriate traveling state at an early stage by the learning control that corrects the amount of operation associated with control of the vehicle.
1. 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.
2. The control device of the vehicle according to claim 1 , wherein the driving control unit is configured to preferentially select traveling in the driving state of the vehicle corresponding to an unperformed region between:
(i) the traveling in the driving state of the vehicle corresponding to the unperformed region in which the amount of operation has never been corrected among the unconverged regions; and
(ii) traveling in the driving state of the vehicle corresponding to a performed region in which the amount of operation has been corrected at least one or more times among the unconverged regions.
3. The control device according to claim 1 , wherein the driving control unit is configured to change, while performing the automatic driving control, the driving state of the vehicle to the driving state of the vehicle that implements the selected traveling.
4. The control device according to claim 3 , wherein the driving control unit is configured to change, when it is impossible to change to the driving state of the vehicle that implements the selected traveling on a current traveling route in the automatic driving control, the current traveling route to another traveling route that implements the selected traveling.
5. The control device according to claim 1 , wherein the driving control unit is configured to change, while performing the automatic driving control, a current traveling route to another traveling route that implements the selected traveling.
6. The control device according to claim 1 , wherein the driving control unit is configured to perform, while performing the automatic driving control, a predetermined driving mode that promotes establishment of a learning permission condition for permitting a learning control of the learning control unit.
7. A control method of a vehicle provided with a power source and a power transfer device, the control method comprising:
setting a target traveling state, and performing automatic driving control by automatically performing acceleration and deceleration based on the target traveling state; and
correcting, 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, while performing the automatic driving control, traveling in the driving state of the vehicle corresponding to unconverged regions is preferentially selected 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.
