  • Patent number: 9965691
    Abstract: In an apparatus for recognizing a lane partition line, a pre-branch section setting unit sets a pre-branch section of a road on which an own vehicle is traveling. The pre-branch section extends a section length from a start line that is positioned closer to the own vehicle than a branch location by an offset distance in a traveling direction of the own vehicle. A determination unit determines whether or not a geographical location of the own vehicle is within the pre-branch section. If it is determined that the geographical location of the own vehicle is within the pre-branch section, a recognition unit suppresses recognition of the lane partition line on an diverging road side of the road on which the own vehicle is traveling. The diverging road is another road branching off from the road on which the vehicle is traveling at the branch location.

  • Publication number: 20170124880
    Abstract: In an apparatus for recognizing a location of an own vehicle, a detector is configured to detect one or more own-vehicle location candidates on roads based on map data. A partition line determiner is configured to, based on a captured image of a road around the own vehicle, determine a line type of each of partition lines extending along edges of the road. A determiner is configured to, for each of the one or more own-vehicle location candidates, under assumption that the own vehicle is at the own-vehicle location candidate, if the own vehicle is passing an intersection, determine, based on the line type of each of partition lines, a degree of confidence indicative of a likelihood that the own-vehicle location candidate at which it is assumed that the own vehicle is present is a location of the own vehicle.
