Abstract

A vehicle control-system includes an automated driving controller and a vehicle-side communication section. The automated driving controller executes automated driving in which at least one out of speed control or steering control of a vehicle is performed automatically, and executes automated driving in a mode from out of plural modes with differing degrees of automated driving. The vehicle-side communication section communicates with a server for managing characteristic information of a vehicle occupant. The automated driving controller controls automated driving based on the characteristic information of the vehicle occupant received from a server-side communication section using the vehicle-side communication section.

First claim

What is claimed is:

1 . A vehicle control system comprising:
an automated driving controller configured to perform automated driving in which at least one out of speed control or steering control of a vehicle is performed automatically in a driving mode selected from a plurality of driving modes which require different degrees of automated driving; and a vehicle-side communication section configured to communicate with a server which stores and manages information associated with a vehicle occupant, wherein the automated driving controller is configured to control the automated driving based on the information associated with the vehicle occupant received from a server-side communication section of the server through the vehicle-side communication section.

2 . The vehicle control system according to claim 1 , wherein
the information associated with the vehicle occupant includes authorization information relating to the driving of the occupant; and the vehicle control system further comprises
an authentication section that authenticates whether or not the vehicle occupant has proper authorization based on the authentication information received from the server-side communication section through the vehicle-side communication section, the authentication section permitting driving the vehicle in cases in which authentication is successful and prohibiting driving the vehicle in cases in which authentication has failed.

3 . The vehicle control system according to claim 1 , wherein
the information associated with the vehicle occupant comprises facial image information including a facial image of the vehicle occupant or a feature quantity in the facial image; and the vehicle control system further comprises
an imaging section configured to capture an image of an interior space in the vehicle, and
an authentication section configured to compare facial image information contained in the information associated with the vehicle occupant with corresponding facial image information of the occupant contained In the image captured by the imaging section to authenticate whether or not the vehicle occupant has proper authorization, the authentication section permitting driving the vehicle in cases in which authentication is successful and prohibiting driving the vehicle in cases in which authentication has tailed.

4 . The vehicle control system according to claim 1 , wherein
the information associated with the vehicle occupant includes permitted travel area information for the vehicle occupant which indicates a permitted travel area in which the vehicle occupant is permitted to drive; and the vehicle control system further comprises
a position identifying section configured to identify a position of the vehicle, and
an authentication section configured to permit driving the vehicle in cases in which the position of the vehicle identified by the position identifying section is within the permitted travel area indicated by the permitted travel area information of the occupant received from the server-side communication section through the vehicle-side communication section, and to prohibit driving the vehicle in cases in which the position of the vehicle identified by the position identifying section is not within the permitted travel area indicated by the permitted travel area information of the occupant received from the server-side communication section through the vehicle-side communication section.

5 . The vehicle control system according to claim 4 , further comprising:
a notification section configured to, in cases in which the automated driving is being executed by the automated driving controller, give a notification that the position of the vehicle will depart from the permitted travel area when the position identified by the position identifying section departs from the permitted travel area; and an operation section configured to receive an operation permitting the vehicle to depart from the permitted travel area; wherein the automated driving controller continues travel of the vehicle in cases in which the operation permitting the vehicle to depart from the permitted travel area has been received by the operation section, and stops the travel of the vehicle in cases in which an operation permitting the vehicle to depart from the permitted travel area is not received by the operation section.

6 . The vehicle control system according to claim 4 , further comprising:
a notification section configured to, in cases in which automated driving is being executed by the automated driving controller, give a notification that the position of the vehicle will depart from the permitted travel area when the position identified by the position identifying section departs from the permitted travel area; and an operation section configured to receive an operation permitting the vehicle to depart from the permitted travel area; wherein the automated driving controller continues travel of the vehicle in cases in which the operation permitting the vehicle to depart from the permitted travel area has been received by the operation section, and stops the execution of the automated driving in cases in which an operation permitting the vehicle to depart from the permitted travel area is not received by the operation section.

7 . The vehicle control system according to claim 1 , wherein
the plurality of automated driving modes include an automated driving-allowed mode, the information associated with the vehicle occupant includes information indicating the automated driving-allowed mode for the vehicle occupant, and the vehicle control system further comprises
a mode controller configured to select the automated driving mode to be executed by the automated driving controller, and to cause the automated driving controller to execute the automated driving within a range of the automated driving-allowed mode received from the server-side communication section through the vehicle-side communication section.

8 . The vehicle control system according to claim 1 , wherein
the information associated with the vehicle occupant includes a proficiency level of the vehicle occupant for driving; and the vehicle control system further comprises
a mode controller configured to select the automated driving mode to be executed by the automated driving controller from a preset range of selectable modes, and to expand the range of selectable modes more the higher the proficiency level received from the server-side communication section through the vehicle-side communication section.

9 . The vehicle control system according to claim 8 , wherein
the mode controller restricts a difference in the degree of automated driving before and after changing the automated driving mode more the lower the proficiency level indicated by the proficiency level information received from the server-side communication section through the vehicle-side communication section,

10 . The vehicle control system according to claim 9 , wherein
the mode controller lengthens a time required to change the mode more the lower the proficiency level indicated by the proficiency level information received from the server-side communication section through the vehicle-side communication section.

11 . A traffic control system comprising:
the vehicle control system according to claim 1 ; and the server.

12 . A vehicle control method performed by an onboard computer, the method comprising:
reading user information that identifies a vehicle occupant; transmitting a request including the read user information to a server for managing the user information; receiving information associated with the ve
