Embodiment approach 2

[0203] Next, Embodiment 2 of the present invention will be described.

[0204] In the first embodiment, the land mark information is used to select the updated map information that best meets the needs of the user from the provided updated map information. In this embodiment, a method of selecting updated map information that best meets user needs from various types of updated map information provided using route information will be described.

[0205] FIG. 27 is a block diagram showing the configuration of mobile terminal 100a according to Embodiment 2 of the present invention. The mobile terminal 100a is a device that uses route information to select updated map information that best meets user needs from various updated map information provided, including: a position information detection unit 101, a node information extraction unit 111, and a map information storage unit. unit 103 , movement history storage unit 102 , route type extraction unit 112 , map information selec...

Embodiment approach 3

[0240] Next, Embodiment 3 of the present invention will be described.

[0241] In Embodiment 1, land mark information such as a destination is stored, and map information is selected based on the information. Furthermore, in Embodiment 2, the travel history of the user is stored, and based on this, the types of roads usually used are determined, and map information is selected using the information.

[0242] Here, when a route is searched using map information with the departure point and destination as input, the route that may be provided may vary depending on the registered map information or the algorithm used to search for the route. Moreover, when navigating a path, there are both easy-to-understand navigation and difficult-to-understand navigation for users. Therefore, this embodiment describes an example in which which map information should be used is automatically determined using the user's travel history and provided route information, and the map information is s...

Abstract

A map information updating device for automatically selecting a piece of map information most suitable for the user from the map information and updating the map information. The map information updating device comprises a map information storage section (103) storing map information, position information detecting section (101) for detecting the current position, a move history storage section (102) for storing a series of detected positions as move history, a map information selecting section (104) and a map information updating section(105) for selecting one of a first updated map information providing section (108) and a second updated map information providing section (109) and acquiring updated map information from the selected providing section, an updated map information storage section (106) for storing the acquired updated map information, and a combining displaying section (117) for combining the map information stored in the map information storage section (103) and the updated map information stored in the updated map information storage section (106) and displaying the combined information.

Description

technical field [0001] The present invention relates to a map information updating device, which updates the map information stored by itself, and in particular relates to a device for updating map information according to a plurality of different types of map information provided for updating. Background technique [0002] In recent years, map information stored in car navigation systems and the like can be updated through communication or recording media, and this technology is being realized. Through the update of map information, even without purchasing a car navigation system, users can obtain the latest information including new roads. On the other hand, map information consists of a large amount of data, and the communication of the map information requires a huge cost. Therefore, it has been proposed to update only a part of the map (for example, refer to Patent Document 1). [0003] FIG. 1 is a system block diagram of the device disclosed in Patent Document 1. As s...
