  • Patent number: 9697730
    Abstract: A method and apparatus for identifying parking areas may include identifying a plurality of coordinates representing vehicle spatial data, partitioning the plurality of coordinates into at least two groups of vehicle locations based on at least one condition existing when the plurality of coordinates was identified, clustering the vehicle spatial data for a first group of the at least two groups of vehicle locations based on proximity, comparing dimensions of the clustered vehicle spatial data for the first group with other location data within the vehicle transportation network information, and defining a respective location of the clustered vehicle spatial data as a parking area of a plurality of parking areas. Each parking area is associated with a respective location in a vehicle transportation network. The parking area information may be used in the identification of a route from an origin to a primary destination.

  • Patent number: 9694673
    Abstract: To assist in maintaining a seal ring in a proper position in a fuel tank assembly, a retaining ring is utilized. The retaining ring surrounds the seal ring to provide a physical barrier to restrict the seal ring. The assembly includes a tank having an opening and a plurality of flanges located about the opening, a fuel pump module, the retaining ring and a seal ring. The retaining ring is located within the plurality of flanges, positioned around the opening and the fuel pump module. The seal ring is located within the plurality of flanges, positioned around the opening and the fuel pump module such that in a radial direction the seal ring is positioned between the fuel pump module and the retaining ring, and in an axial direction the seal ring is positioned between the fuel pump module and the fuel tank.

  • Publication number: 20170186186
    Abstract: A self-position calculating apparatus includes: a light projector projecting a patterned light beam onto a road surface around a vehicle; and a camera capturing an image of the road surface including an area onto which the patterned light beam is projected. The apparatus calculates an orientation angle of the vehicle from a position of the patterned light beam, and calculate an amount of change in orientation based on temporal changes in multiple feature points on the road surface. The apparatus calculates current position and orientation angle by adding the amount of change to initial position and orientation angle. If a condition under which the multiple feature points are detected does not satisfy a first criterion, the apparatus sets the current position at that time and the orientation angle at the initial position and orientation, and starts adding the amount of change to the initial position and orientation angle.
