Patent number: 8234064Abstract: It is possible to display a lane guide map that takes into consideration connections between each of the lanes (m1 to m8) and reduction in the visibility of the lane guide map is prevented. The invention includes a current position detecting unit; a lane list setting processing means that produces a lane list (LsI 1) that takes into consideration connections between each of the lanes for lane groups (LkI 1 to LkI 3) in road links that are present in a lane list display section; a rendering range determination processing means that determines whether or not the number of lanes in the lane list (LsI 1) is larger than the number of lanes that has been set in a display unit (35); and a display range adjustment processing means that selects predetermined lanes in the lane list (LsI 1) and displays only the selected lanes. Lanes that have a low display necessity can be removed.Type: GrantFiled: October 25, 2007Date of Patent: July 31, 2012Assignee: Aisin AW Co., Ltd.Inventors: Shino Oonishi, Takaaki Nakayama

Publication number: 20120158290Abstract: A navigation user interface displays a route to be navigated over a road view map. If a user selects a particular segment of the displayed route, text-based directions associated with the particular route segment are displayed, with a selectable area to return to the map view. Additionally, as the road view map is zoomed in, when the zoom level reaches a threshold zoom level, the navigation user interface automatically transitions to displaying a satellite view map overlaid with at least a portion of the route to be navigated.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Applicant: Microsoft CorporationInventors: Aarti Bharathan, Liang Chen, Jae Pum Park

Publication number: 20120150433Abstract: Aspects of the invention relate to the use of electronic maps and providing information about intersecting streets. A given region of interest on a map may include any number of features. Features of interest, including road segments and intersections, can be filtered to remove non-street data. The results may be analyzed according to individual street segments. Each segment may be identified by a feature ID, and the relationship each segment has with a given intersection is analyzed. Thus, the direction of a segment into or out of an intersection is determined, along with the physical locations of the beginning and end of the segment. This information is used to provide robust map information that may be displayed to a user. Heuristics can be applied to the map information to provide coherent address or direction information to the user for a given point of interest.Type: ApplicationFiled: February 15, 2012Publication date: June 14, 2012Applicant: GOOGLE INC.Inventor: Tudor Hulubei

Publication number: 20120136570Abstract: Provided are a device for automatically generating route restriction information of intersections between main roads and narrow streets, and a method therefor. With respect to a specific intersection which is an intersection between a main road and a narrow street, firstly, it is determined to prohibit a right turn and passing through the intersection. Under these conditions, when it is sufficiently confirmed, by using external information, that the right turn and passing through the intersection can be allowed at the specific intersection, the route restriction regarding the direction is released. Probe information and traffic restriction data are used for the external information.Type: ApplicationFiled: March 15, 2010Publication date: May 31, 2012Applicant: TOYOTA MAPMASTER INCORPORATEDInventors: Yumiko Yamashita, Takashi Yamada, Shintaro Ohsaki, Cheng Li

Patent number: 8170795Abstract: A vehicle navigation system helps guide a driver to a destination by enhancing visualization of upcoming intersections. The navigation system stores animation data that depicts the intersection as it will appear to the driver. The animation data may be a sequence of images (e.g., digital camera images) taken at intervals before and after the intersection. The navigation system may show the images in synchronism with the progress of the vehicle to provide an animated display of the intersection for the driver. The animated display aids the driver with following a recommended navigation route to the destination.Type: GrantFiled: August 3, 2006Date of Patent: May 1, 2012Assignee: Harman Becker Automotive Systems GmbHInventors: Christian Brülle-Drews, Volker Grabs

Patent number: 8165804Abstract: A normal route guidance of a navigation apparatus based on guidance information retrieved from a hard disk drive is switched to a turn list display based on the guidance information from an external memory when a vehicle enters a high-altitude area. The navigation apparatus calculates a navigation route to a destination, and determines if the navigation route passes a high-altitude area. If the route passes the high-altitude area, the guidance information of a high-altitude area section of the navigation route is written in the eternal memory. Thus, while the vehicle is traveling, the navigation apparatus having the hard disk drive continues its navigation operation by displaying the turn list even when an operation of the hard disk drive is stopped due to a function restriction in the high-altitude area.Type: GrantFiled: December 18, 2008Date of Patent: April 24, 2012Assignee: DENSO CORPORATIONInventor: Kenji Takashima

Patent number: 8131466Abstract: When a vehicle travels along a guidance path and approaches an intersection, a vehicle navigation system determines crossing points between a circle having its center set to the intersection and a predetermined radius, and an approach link and an exit link for the intersection. The system also sets a direction connecting the crossing point for the approach link and the intersection as an approach direction, and sets a direction connecting the intersection and the crossing point for the exit link as an exit direction. The system determines a traveling direction at the intersection based on an angular difference between the approach direction and the exit direction, and determines a display position of the intersection on a screen. Further, an enlarged intersection image is drawn such that the approach direction is aligned with a 12 o'clock direction on the screen.Type: GrantFiled: February 8, 2008Date of Patent: March 6, 2012Assignee: Alpine Electronics, Inc.Inventor: Tatsunori Iwatani
