Abstract: A vehicle can execute an automatic driving mode and a manual driving mode as a driving mode. An assistance device supports mode switching from the automatic driving mode to the manual driving mode. The assistance device includes an acquisition interface and a notification interface. The acquisition interface acquires data indicating a situation around the vehicle. The notification interface that communicates a candidate position derived based on the data acquired by the acquisition interface, the candidate position being a candidate of a position where the mode switching should be executed.

Abstract: A communication interface can connect to an information terminal. When detecting the connection between the communication interface and the information terminal, a verification interface verifies the security status of the information terminal. When there is no problem in the security status of the information terminal verified by the verification interface, a display displays an image based on an image signal received by the communication interface from the information terminal. The operation interface accepts an operation on the image displayed by the display. The communication interface transmits an operation signal responsive to the operation accepted by the operation interface to the information terminal, and then receives an image signal as a result of processing by the information terminal in accordance with the operation signal from the information terminal.

Abstract: A content acquisition interface acquires a content. An information acquisition interface acquires traveling condition information on a vehicle. A control interface causes a display interface to display the content when the traveling condition information acquired by the information acquisition interface indicates an automatic driving level equal to or higher than a threshold value or causes the display interface to display information on traveling-based restriction when the traveling condition information acquired by the information acquisition interface does not indicate an automatic driving level equal to or higher than the threshold value.
