  • Publication number: 20190197323
    Abstract: Travel assistance devices and programs obtain a captured image that captures a surrounding environment of a vehicle by an imaging device having a start point of a driver's line of sight and an optical axis corresponding to a driver's line-of-sight direction. The devices and programs identify, based on the captured image and map information of an area around the vehicle, a location where a connecting road is present in the captured image. The connecting road is a road connecting to a traveling road of the vehicle at a divergence point present around the vehicle. The devices and programs determine driver's visibility of the connecting road based on a positional relationship between the location of the connecting road and a location of an obstacle present around the vehicle in the captured image and output a result of the determination.

  • Patent number: 8370059
    Abstract: A display is divided into two regions, a standard region and an enlarged region with a user positioned is at an angle relative to the display. The standard region is formed on a side nearer the user and the enlarged region is formed on a side farther from the user. When the navigation device displays guidance information, information displayed in the standard region is displayed on a standard scale, while information displayed in the enlarged region is displayed enlarged relative to the standard scale. Since the display on the side farther from the user position is thus enlarged, the user can more easily view that guidance information.

  • Publication number: 20100332130
    Abstract: A vehicle navigation apparatus determines whether or not the currently traveled route having a current vehicle position matches with estimated routes after determining, on the basis of the traveled route history, the estimated routes which correspond to destination candidates. Then, the navigation apparatus further determines whether or not the subsequent portion of the estimated route overlaps with other estimated route, for selecting one of the destination candidates. The vehicle navigation apparatus thus selects the destination candidate, in a highly accurate manner in terms of user preference, based on the traveled route history.
