  • Patent number: 11869251
    Abstract: A driving support method including: detecting a first boundary point group including boundary points forming a lane boundary line, using a sensor mounted on a vehicle; converting a coordinate system of the first boundary point group to the same coordinate system as a coordinate system of map data; and performing matching between a first point group constituted by boundary points not close to each other in either one of a second boundary point group including boundary points forming a lane boundary line in the map data and the first boundary point group and the other of the first boundary point group and the second boundary point group.

  • Publication number: 20210262825
    Abstract: A travel assistance method causes a sensor to detect a lane boundary present around a vehicle, calculates own positions of the vehicle, converts a coordinate system of the detected lane boundary into a coordinate system equivalent to map data stored in in accordance with the own positions, and integrates configuration information on the lane boundary included in the map data with the lane boundary of which the coordinate system is converted to generate integrated data, wherein an integrated range is determined, when the configuration information is integrated with the lane boundary of which the coordinate system is converted, such that the lane boundary includes at least either parts having different curvatures or straight parts directed in different directions, and the configuration information is mapped with the lane boundary of which the coordinate system is converted to generate the integrated data while including at least the determined integrated range.
