Abstract

A mobile-body navigation device includes a route search unit 12 for searching for a route to a destination; a communication device 7 and communication interface unit 9 constituting a receiving unit for receiving information about a deviation-prone connection route on a route identified in accordance with probe information; a deviation-prone connection route caution instructing unit 14 for giving instructions to send notification of the presence or absence of the deviation-prone connection route on the route the route search unit 12 searches for in accordance with the information about the deviation-prone connection route the receiving unit receives; and a display device 8 for displaying a guide map including the presence or absence of the deviation-prone connection route on the route in response to the instructions.

Claims

1. A mobile-body navigation device comprising:

a route searching unit that searches for a route to a destination;

a receiver that receives information about a deviation-prone connection route on the route identified in accordance with probe information;

an instructing unit that gives instructions to send notification of presence or absence of a deviation-prone connection route on the route the route searching unit searches for in accordance with the information about the deviation-prone connection route the receiver receives; and

a display controller that displays a guide map including the presence or absence of the deviation-prone connection route on the route in response to the instructions.

2. The mobile-body navigation device according to claim 1, further comprising:

a deviation-prone connection route storage that stores the information about the deviation-prone connection route the receiver receives, wherein the instructing unit gives the instructions to send notification of the presence or absence of the deviation-prone connection route on the route the route searching unit searches for in accordance with the information about the deviation-prone connection route read out of the deviation-prone connection route storage.

3. The mobile-body navigation device according to claim 1, wherein when the receiver fails to receive the information about the deviation-prone connection route, the receiver retries to receive the information about the deviation-prone connection route.

4. The mobile-body navigation device according to claim 1, further comprising:

an input device that accepts input, wherein

the instructing unit gives the route searching unit instructions to re-search a route when the input device accepts a request for re-searching for a route; and

the route searching unit receives the instructions and re-searches for the route.

5. The mobile-body navigation device according to claim 1, wherein the receiver receives the information about the deviation-prone connection route at intervals of a prescribed distance covered by a mobile body or at intervals of a prescribed elapsed time.

6. A mobile-body navigation system comprising:

a mobile-body navigation device as defined in claim 1; and

a probe server comprising a deviation-prone connection route identifying unit that identifies a deviation-prone connection route on a route by collecting probe information, and a returning unit that sends the information about the deviation-prone connection route the deviation-prone connection route identifying unit identifies back to the mobile-body navigation device.

7. The mobile-body navigation system according to claim 6, wherein the probe server transmits, if any alteration in the information about the deviation-prone connection route is detected from the probe information, the information about the deviation-prone connection route after the alteration to the mobile-body navigation device that uses as the guide route the route including the deviation-prone connection route indicated by the information about the deviation-prone connection route.
