Abstract: A travel path data generation apparatus for generating travel path data inside an intersections for automated driving includes a travel path data generator that generates the data of the travel path in such a way that, using an absolute trajectory of actual traveling of a vehicle inside the intersection, the travel path data generator fits an estimated trajectory of the actual traveling of the vehicle inside the intersection into data of lane network connected to the intersection.

Abstract: The traffic lane position information output device includes an imaging unit that images a periphery of a vehicle, a traffic lane extraction unit that extracts a traffic lane from an image captured by the imaging unit, and a traffic lane position information output unit that outputs traffic lane position information indicating a position of the traffic lane extracted by the traffic lane extraction unit. The traffic lane position information output unit outputs the traffic lane position information in a predetermined case where the traffic lane appears correctly in the image captured by the imaging unit.

Abstract: An onboard device includes a map data provision unit, a computation unit and a determination unit. The map data provision unit is configured to provide map data pertaining to a road on which a vehicle travels. The computation unit is configured to, when vehicle probe data indicating the positions and shapes of a road and a feature in the vicinity of the vehicle is given, compare the vehicle probe data with the map data provided from the map data provision unit to calculate a difference. The determination unit is configured to, when the difference exceeds a threshold value beyond which control of the vehicle based on the map data and the probe data will be impaired, determine the detected vehicle probe data as vehicle probe data to be transmitted.

Abstract: A travel path data generation apparatus includes an intersection feature data generator that, by using data of travel paths outside intersections, generates intersection feature data representing features of the intersections and a sample data generator that associates the intersection feature data with motion trajectory data showing actual motion trajectories of vehicles inside intersections and generates sample data serving as samples of association between the feature of the intersection and the actual motion trajectories inside the intersection; and a travel path data generator that searches the sample data for the sample that to corresponds to specific intersection feature data representing a feature of a given intersection; specifies the motion trajectory data associated with the specific intersection feature data; and provides the specified motion trajectory data as data of travel paths inside intersections that corresponds to the given intersection.

Abstract: In a lane keeping apparatus, a first retrieving unit retrieves, for each lane, a continuously travelable distance. The continuously travelable distance for each lane represents a distance for which an own vehicle is able to travel while keeping the corresponding lane. A first identifying unit identifies a road, as a traveling road, on which the own vehicle is traveling, and one of the lanes, as a traveling lane, in which the own vehicle is traveling. A first determiner compares a continuously travelable own-lane distance with at least one continuously travelable other-lane distance to accordingly determine whether lane change from the traveling lane to at least one other lane included in the lanes is suitable.

Abstract: In response to confirmation request from an onboard terminal in a state where updated data after start of a temporary road change is available, a map update server distributes the updated data and instructs the onboard terminal to temporarily use the updated data. In response to the confirmation request in a state where the updated data after end of a temporary road change is available, the server instructs the onboard terminal to use the updated data from before the start of the temporary road change. In response to being instructed to temporarily use the updated data, the terminal uses the updated data that has been distributed. In response to being instructed to use the updated data from before the start of a temporary road change, the terminal temporarily uses the updated data by using map data from before the start of the temporary road change instead of the updated data.

Abstract: A vehicle navigation system disposed in a vehicle executes a route guidance function that calculates a first route by prioritizing a special lane over a normal lane as a route calculation condition and performs route guidance when a special lane use option is turned on. A determination unit determines whether the vehicle is traveling in a parallel route section in which the special lane and normal lane are in parallel. If the vehicle is traveling in the parallel route section, a second route calculation unit calculates a second route towards the destination based on an assumption that the vehicle is traveling in the normal lane. In addition, a second route guidance unit outputs a second guidance phrase at a second guidance point, such that the second guidance phrase includes a conditional phrase that conveys that the vehicle is not in the special lane.
Abstract translation: 布置在车辆中的车辆导航系统执行路线引导功能，其通过将正常车道上的专用车道优先排列为路线计算条件来计算第一路线，并且在专用车道使用选项被打开时执行路线引导。 确定单元确定车辆是否在特殊车道和正常车道并行的并行路线部分中行驶。 如果车辆在并行路线区段中行驶，则第二路线计算单元基于车辆在正常车道行驶的假设来计算朝向目的地的第二路线。 此外，第二路径引导单元在第二引导点输出第二引导短语，使得第二引导短语包括传达车辆不在专用车道中的条件短语。

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 sign recognition system according to an exemplary aspect of the present disclosure is configured to, when image data of a sign is captured by a vehicular camera, recognize one or more characters, which are included in the sign and belong to at least one specified character type, from the image data, thus extracting, from the image data, the recognized one or more characters. The sign recognition system is also configured to store a sign dataset in a sign database; the sign dataset includes (i) an installation-position information item indicative of the installation position of the sign, and (ii) an attribute information item about the sign.

Abstract: An all-one-way network data for autonomous driving is generated according to traffic information of a road data included in a navigation map data. The lane network data for autonomous driving is generated based on the all-one-way network data according to information of a numerical number of lanes in the road data. A virtual lane boundary data is generated based on the all-one-way network data. A position of the lane network data and a position of the virtual lane boundary data are corrected according to a basic road map data and an aerial photograph data.
