The preference data of the occupant is stored in the preference data storage unit and associated with the identification data.

Abstract: An information output device includes: an event detection unit that detects an event occurring inside or outside a vehicle; a member identification unit that identifies a person or persons who can perceive the event as a first member; an event storage unit that stores event data related to the detected event in association with the first members; and a data output unit that automatically outputs the event data stored in the event storage unit. The member identification unit identifies a person or persons who can view the event data outputted from the data output unit as a second member. The information output device further comprises an output control unit that determines whether the second members include persons other than the first members, and that prohibits the data output unit from automatically outputting the event data upon determining the second members include persons other than the first members.

Abstract: An information processing device includes a controller, a ride detection device configured to detect a ride of a user, a storage device configured to store action data of the user, an output device configured to output question data for requesting an answer from the user, and an input device configured to receive an input from the user. The controller outputs, from the output device, output data including at least a question regarding an action of the user taken before riding in a vehicle in accordance with positional information of the vehicle when detecting the ride of the user based on a signal acquired from the ride detection device, acquires an answer to the question from the user as input data via the input device, and associates the input data with the positional information of the vehicle or a POI to store the associated data in a storage device.

Abstract: An information output device is provided, which includes a request acquisition unit that acquires a maintenance request for a vehicle; a user information acquisition unit that acquires information regarding each of a plurality of users; a message generator that generates a message associated with the maintenance request acquired by the request acquisition unit; and a message output unit that outputs the message generated by the message generator. The user information acquisition unit acquires maintenance records of the vehicle that are records of maintenance executed for the vehicle by the plurality of users. The message generator selects a presentation destination user to be presented with the message and generates the message based on a maintenance record of the presentation destination user among the maintenance records of the vehicle. The maintenance record of the presentation destination user is a record of the maintenance executed by the presentation destination user.

Abstract: A lane information management method for managing lane information using a processor is provided. This method includes acquiring road map information and information on a travel history that is represented by a travel trajectory on a road map, determining, using a plurality of the travel histories, whether or not a lane connected to an intersection is in a multiple lane form in which two or more lines of vehicles are formed on a single lane, and managing the lane information, including a result of determination of the multiple lane form in the lane information.

Abstract: A surrounding situation display method of detecting a surrounding situation around a host vehicle with an autonomous driving function and displaying the detected surrounding situation, includes displaying, in a varying display bar that has a prescribed display frame and displays an indication position within the display frame in synchronization with movement of an attention target, the indication position having moved to one endpoint of the varying display bar as a timing when an action of the host vehicle is changed by the autonomous driving function.

Abstract: A display control device includes: a turn signal installed in a vehicle; indicators for displaying a lighting state of the turn signal to an occupant of the vehicle; and a controller for controlling the lighting state of the turn signal and a lighting state of the indicators. The controller makes timing of starting to turn on the turn signal and timing of starting to turn on the indicators different from each other.

Abstract: A mobile body surroundings display method is performed by a mobile body surroundings display apparatus that includes an image capturing element that acquires surroundings information on a mobile body by image capturing, a controller that creates a captured image using the surroundings information and a virtual image representing a situation around the mobile body, and a display that displays the virtual image. The method detects an attention-required range around the mobile body, creates a captured image of the attention-required range, and displays the captured image of the attention-required range on the display.
