Abstract

A map information update apparatus includes: a map information storage unit that stores district map information including a plurality of division areas; a receiver that receives a broadcast wave carrying information of one or more of the plurality of division areas; a wireless communication unit that receives a radio wave carrying information of one or more of the plurality of division areas by wireless communication; and an information update unit that updates, when the district map information does not satisfy a first basis, the district map information for each division area based on the information carried by the broadcast wave received by the receiver and updates, when the district map information satisfies the first basis, the district map information for each division area based on the information carried by the radio wave received by the wireless communication unit.

First claim

1 . A map information update apparatus comprising:
a map information storage unit that stores district map information including a plurality of division areas; a receiver that receives a broadcast wave carrying information of one or more of the plurality of division areas; a wireless communication unit that receives a radio wave carrying information of one or more of the plurality of division areas by wireless communication; and an information update unit that updates, when the district map information does not satisfy a first basis, the district map information for each division area based on the information carried by the broadcast wave received by the receiver and updates, when the district map information satisfies the first basis, the district map information for each division area based on the information carried by the radio wave received by the wireless communication unit.

2 . The map information update apparatus according to claim 1 , wherein
the wireless communication unit includes a first wireless communication unit that performs wireless communication using a mobile phone network and a second wireless communication unit that performs wireless communication directly with another terminal apparatus, and the information update unit updates, when the district map information satisfies the first basis and does not satisfy a second basis which is harder to achieve than the first basis, the district map information for each division area based on the information received by the first wireless communication unit and updates, when the district map information satisfies the second basis, the district map information for each division area based on the information received by the second wireless communication unit.

3 . The map information update apparatus according to claim 2 , wherein
the first basis is that a degree of the update of the district map information is equal to or more than a threshold value that is set to 0.4 to 0.7, and the second basis is that a degree of the update of the district map information is equal to or more than a threshold value that is set to 0.7 to 0.9.

4 . The map information update apparatus according to claim 1 , wherein
edition identification information that indicates novelty is imparted to each information of one or more of the plurality of division areas, and the information update unit determines whether or not edition identification information of the information for a division area received by the receiver is matched to edition identification information of the information for the division area of the district map information stored in the map information storage unit and determines whether or not the district map information is updated for each division area based on the determination result.

5 . A map information update apparatus comprising:
a map information storage unit that stores at least district map information including a plurality of division areas; a receiver that receives a broadcast wave carrying information of one or more of the plurality of division areas; a first wireless communication unit that receives a radio wave carrying information of one or more of the plurality of division areas by performing wireless communication using a mobile phone network; a second wireless communication unit that receives a radio wave carrying information of one or more of the plurality of division areas by performing wireless communication directly with another terminal apparatus; and an information update unit that updates the district map information for each division area based on the information received by the receiver, the first wireless communication unit, or the second wireless communication unit and that acquires information of one or more of the plurality of division areas using any of the receiver, the first wireless communication unit, and the second wireless communication unit in response to a rate of the update of the district map information and updates the district map information for each division area based on the acquired information.

6 . The map information update apparatus according to claim 1 , which is provided on a mobile body.

7 . The map information update apparatus according to claim 1 , which is provided on a portable terminal.

8 . A map information update system comprising:
a map information update apparatus according to claim 1 ; and a server apparatus that transmits information of one or more of the plurality of division areas.
