Patent number: 8311736Abstract: A navigation device receives a differential map data from a map delivery server via a communication line. The map delivery server checks whether there is a new intersection on a navigation route searched by the navigation device after updating a map data. The navigation device acquires a differential map data containing the intersection from the map delivery server. Then, an update map data selection section determines whether the intersection can be updated in time. An update order determination section updates the differential map data which can be updated in time in ascending order of time required to reach the intersection.Type: GrantFiled: June 4, 2009Date of Patent: November 13, 2012Assignees: Hitachi, Ltd., Clarion Co., Ltd.Inventors: Osamu Tomobe, Yukihiro Kawamata, Yukio Miyazaki, Takayoshi Shimokawa

Publication number: 20080301263Abstract: The present invention provides, in a car navigation system, a unit of notifying a user of the update contents of map data prior to the downloading of the map data. A vehicle-mounted terminal sets a difference update area in accordance with a selection made by a user and sends a difference update request to a map updating server. If an update mode in this case is “update after outline display”, the vehicle-mounted terminal downloads an outline update map from the map updating server. The outline update map is displayed on a display unit of a display. Here, when a download start button displayed on the display unit is depressed, the vehicle-mounted terminal downloads a detailed update map from the map updating server. The detailed update map is then displayed on the display unit of the display. Furthermore, an updating process is performed on the map data stored in a terminal DB.Type: ApplicationFiled: August 6, 2008Publication date: December 4, 2008Applicant: Hitachi, Ltd.Inventors: Yoshitaka ATARASHI, Yukihiro Kawamata, Mariko Okude, Yukio Miyazaki
