in response to determining that the driver of the vehicle has previously been permitted to drive the vehicle under the automatic driving mode:

skip the evaluation of the driving skill of the driver; and

proceed to control the driving mode of the vehicle to switch from the manual driving mode to the automatic driving mode without performing the evaluation of the driving skill of the driver.

10. The automatic driving control apparatus according to claim 1 ,

wherein the automatic driving control apparatus further comprises a driver identification unit configured to identify the driver, and

wherein when the driver is recognized as being previously identified by the driver identification unit, the at least one processor evaluates the driving skill of the driver based on i) previously evaluated driving skill of the driver evaluated when the driver was previously identified by the driver identification unit and ii) currently evaluated driving skill of the driver.

11. The automatic driving control apparatus according to claim 2 ,

wherein the automatic driving control apparatus further comprises a driver identification unit configured to identify the driver, and

wherein when the driver is recognized as being previously identified by the driver identification unit, the at least one processor evaluates the driving skill of the driver based on i) previously evaluated driving skill of the driver evaluated when the driver was previously identified by the driver identification unit and ii) currently evaluated driving skill of the driver.

12. The automatic driving control apparatus according to claim 3 ,

wherein the automatic driving control apparatus further comprises a driver identification unit configured to identify the driver, and

wherein when the driver is recognized as being previously identified by the driver identification unit, the at least one processor evaluates the driving skill of the driver based on i) previously evaluated driving skill of the driver evaluated when the driver was previously identified by the driver identification unit and ii) currently evaluated driving skill of the driver.

13. The automatic driving control apparatus according to claim 4 ,

wherein the automatic driving control apparatus further comprises a driver identification unit configured to identify the driver, and

wherein when the driver is recognized as being previously identified by the driver identification unit, the at least one processor evaluates the driving skill of the driver based on i) previously evaluated driving skill of the driver evaluated when the driver was previously identified by the driver identification unit and ii) currently evaluated driving skill of the driver.

14. The automatic driving control apparatus according to claim 1 , wherein the at least one processor is configured to calculate the shift permission time period such that the shift permission time period becomes shorter as the calculated evaluation value of the driving skill becomes higher.

15. A automatic driving control apparatus for a vehicle, the vehicle having a driving mode that switches between 1) a manual driving mode in which a driver manually performs driving operation of the vehicle and 2) an automatic driving mode in which driving operation is performed automatically along a set target traveling route, the automatic driving control apparatus comprising circuitry configured to:
