Abstract

A mobile-body navigation device includes a communication device 7 and a communication interface unit 9, which constitute a receiving unit for receiving information about a deviation-prone connection route identified using probe information, a deviation-prone connection route caution instructing unit 14 for instructing to send a notification when a vehicle approaches a deviation-prone point on the guide route in accordance with the information about the deviation-prone connection route the receiving unit receives, and a display device 8 and a map display unit 13, which constitute a display unit for displaying a guide map of the guide route in response to the instruction.

Claims

1-6. -6. (canceled)

7. A mobile-body navigation device comprising:

a positional information acquiring unit that acquires positional information of a mobile body;

a route searching unit that searches for a recommended route using map data recorded in a map database, and the positional information and destination of the mobile body;

a communication device for transmitting, when the positional information of the mobile body comes within a prescribed range from a next connection point while the mobile body is moving along the recommended route, information about the connection to a server, and for receiving information about a deviation-prone connection route transmitted from the server in accordance with the information about the connection; and

a map display controller that causes a display device to display the information about the deviation-prone connection route.

8. The mobile-body navigation device according to claim 7, wherein the map display controller displays on the display device the recommended route and a deviation-prone road on the deviation-prone connection route at the same time, displays the recommended route emphatically, and displays the deviation-prone road in a display mode that will call attention of a driver.

9. A route display method of displaying a recommended route of a mobile body on a display device, the route display method comprising:

a step of acquiring positional information of the mobile body;

a step of searching for the recommended route using map data, and the positional information and destination of the mobile body;

a step of transmitting, when the positional information of the mobile body comes within a prescribed range from a next connection point while the mobile body is moving along the recommended route, information about the connection to a server;

a step of receiving information about a deviation-prone connection route transmitted from the server in accordance with the information about the connection; and

a step of causing a display device to display the information about the deviation-prone connection route.

10. A server for carrying out communication with a navigation device mounted on a mobile body, the server comprising:

a database for storing information about a deviation-prone connection route of the mobile body; and

a communication interface for receiving information about a connection transmitted from the navigation device when positional information of the mobile body comes within a prescribed range from a next connection point while the mobile body is moving along a recommended route, and for transmitting, when receiving the information about the connection, the information about the deviation-prone connection route to the navigation device.

11. The server according to claim 10, wherein the database stores the information about the deviation-prone connection route of the mobile body in accordance with each time period and each weather.

12. A navigation system including a navigation device mounted in a mobile body and a server for carrying out communication with the navigation device, wherein

the server comprises:
