Abstract: A map update system includes a map data storage unit storing therein map data. The map update system acquires a position of a road marking painted on a surface of a road. The map update system acquires a determination value to be subjected to determination of blurring of the road marking based on at least either of measurement information on the road marking and analysis information analyzing the measurement information. The map update system compares the determination value to a reference value and acquires blur information indicating a degree of blurring of the road marking. The map update system reflects the blur information in the map data.

Abstract: A server acquires location information data and direction information data. The location information data indicates a travel path of vehicles with discrete locations. The direction information data indicates a traveling direction at each location indicated by the location information data. The server generates information about a new travel route that does not exist in the map data, based on off-route location information data indicative of a travel path deviated from travel routes existing in map data. The server estimates partial travel routes indicative of parts of the new travel route, based on the off-route location information data and the direction information data indicative of associated traveling directions of vehicles. The server then estimates the shape of the new travel route, based on the estimated partial travel routes.
Abstract translation: 服务器获取位置信息数据和方向信息数据。 位置信息数据表示具有离散位置的车辆的行驶路径。 方向信息数据表示由位置信息数据指示的每个位置处的行进方向。 基于路线位置信息数据表示与地图数据中存在的行驶路线偏离的行驶路径，服务器生成关于地图数据中不存在的新的行驶路线的信息。 服务器基于路线前位置信息数据和指示车辆的相关行驶方向的方向信息数据来估计指示新行驶路线的部分的部分行驶路线。 然后，服务器基于估计的部分旅行路线来估计新的行进路线的形状。

Abstract: A display system applied to a vehicle includes a navigation device guiding a route to a destination and a display control device displaying multiple route guidance contents in superimposed manner on a road surface using a head-up display. When the navigation device determines that a first route guidance and a second route guidance included in route guidance information are successive guidance, (i) the navigation device concurrently displays images of the first route guidance and the second route guidance, and (ii) the display control device activates display of a first guidance content that performs the first route guidance, and then activates display of a second guidance content that performs the second route guidance after deactivating the display of the first guidance content.

Abstract: A display control device for a vehicle to control displaying a virtual image includes: a display image generator that generates a guide object display image for guiding a travel route; a distance recognition unit that recognizes a remaining distance from a current location of the vehicle to a guide target point; and a display controller that: displays a non-superimposed virtual image not to be superimposed on a specific superimposition target when the remaining distance is longer than a switch distance; and displays a superimposed virtual image to be superimposed on the specific superimposition target switched from the non-superimposed virtual image when the remaining distance becomes shorter than the switch distance.

Abstract: A virtual image is superimposed on a foreground scenery of an occupant. It is determined whether a road condition, for associating a display position of the virtual image with a position of an object in the foreground scenery with respect to a road on which the vehicle travels, is satisfied. The virtual image is generated as a superposing virtual image that presents information by associating the display position with the position of the object when the road condition is satisfied. At least a part of the virtual image is generated as a non-superimposing virtual image that presents the information without associating the display position with the position of the object when the road condition is not satisfied.

Abstract: A data generation device includes a data generation unit configured to generate data. The data generation unit is further configured to generate, as the data, traffic light identification data including lane information for identifying a lane in which a vehicle is traveling, traffic light information for identifying a plurality of traffic lights installed at an intersection to which the lane is connected, and confidence information indicating a degree of confidence set for each of the plurality of traffic lights. The traffic light identification data has a data structure that allows the traffic light that should be trusted to be identified based on the degrees of confidence set for the plurality of traffic lights depending on the lane in which the vehicle is traveling.

Abstract: A virtual image is superimposed on a foreground scenery of an occupant of a vehicle. A position of the vehicle is acquired. High-precision map information or low-precision map information with lower accuracy than the high-precision map information, corresponding to the position is acquired. The virtual image is generated in a first display mode based on the high-precision map information when the high-precision map information can be acquired. The virtual image is generated in a second display mode different from the first display mode based on the low-precision map information when the high-precision map information cannot be acquired.
