  • Patent number: 10126743
    Abstract: A vehicle navigation route search system, method, and program search for a recommended route in the case where a vehicle travels by autonomous driving control in an autonomous driving section where autonomous driving control of the vehicle is permitted. The system, method, and program calculate a cost value by using a cost table for autonomous driving control which is set such that a route that is more suitable for traveling by autonomous driving control has a lower cost value, and search for the recommended route based on the calculated cost value.
    Type: Grant

  • Patent number: 8583355
    Abstract: A road shape estimating device has a data obtaining processing unit for obtaining interpolation point data for a plurality of shape interpolation points which are set along a road and represent a shape of the road, a radius calculation processing unit for calculating a radius of curvature at each of the shape interpolation points based on the interpolation point data for a predetermined section of the road, a corner detection processing unit for detecting a corner in the predetermined section based on the radii of curvature, and a corner dividing processing unit for dividing the corner at a shape interpolation point having a radius of curvature equal to or larger than a threshold in the detected corner. The threshold is set corresponding to an average value of radii of curvature at respective shape interpolation points in the detected corner.
