Benefits of technology

[0009] Thus, an object of various exemplary implementations of the broad principles described herein is to provide a map information delivery system capable of preferentially receiving the updating information based on the host vehicle's state. For example, if the data size of the updating information is too large to be used in the navigation apparatus within a predetermined time period (e.g., from about 20 to about 35 seconds), the map may be sequentially updated to provide the effective map information quickly during traveling of the host vehicle.

Problems solved by technology

That is, the updating information suitable for the state of the host vehicle cannot be preferentially received.

Embodiment Construction

[0024] A general structure of an exemplary map information delivery system 1 will be described referring to FIG. 1.

[0025] Referring to FIG. 1, the map information delivery system 1 may include a navigation apparatus 2, a map information delivery center 3, which delivers updating information for updating map information to the navigation apparatus 2, and a network 4. The navigation apparatus 2 and the map information delivery center 3 may transmit and receive various kinds of information via the network 4. The structure of the navigation apparatus 2 will be described in detail later referring to FIG. 2.

[0026] Referring to FIG. 1, the map information delivery center 3 may physically, functionally, and or conceptually include a controller (e.g., server 10) and one or more memories (such as, for example, a center map information DB 14 and / or a navigation updating historical information DB 15), and a center communication unit 16. The server 10 may include the inner storage unit, for ex...

Abstract

A map information delivery system, including a navigation apparatus, is capable of preferentially receiving map updating information based on a host vehicle's state. The updating information may be preferentially received based on whether a destination has been set, a location of the updating information relative to an updating position or a destination, and / or the size of the updating information.

Description

INCORPORATION BY REFERENCE [0001] The disclosure of Japanese Patent Application No. 2006-174560 filed on Jun. 23, 2006, including the specification, drawings, and abstract is incorporated herein by reference in its entirety. BACKGROUND [0002] 1. Related Technical Fields [0003] Related technical fields include map information delivery systems and, in particular, map information delivery system which deliver updating information for updating the map information from a map information delivery center to a navigation apparatus. [0004] 2. Related Art [0005] Navigation apparatuses are increasingly being installed in vehicles. Such a navigation apparatus is structured to detect a current position of a vehicle using a GPS receiver. The apparatus to obtains map data corresponding to the current position from a recording medium such as a DVD-ROM and HDD, or a network. Then, the apparatus displays the obtained map data on a liquid crystal monitor. The obtained map data, which contains the curr...
