Abstract

A route provision apparatus includes: a veering detecting unit for employing the current positioning data obtained by a position acquisition unit and route data for an originally determined travel route to detect whether a vehicle has veered away from a determined travel route; and a travel route determination unit for determining a new travel route when the vehicle has veered away from the determined travel route, wherein the travel route determination unit employs the detection results obtained by the veering detecting unit 62 to determine a new travel route in accordance with one or more of route determination conditions.

Claims

1. A route provision apparatus comprising:

a position acquisition unit configured to obtain current positioning data including information of a current position of a mobile object;

a veering detecting unit configured to employ the current positioning data to detect a veering of the mobile object from a determined travel route; and

a travel route determination unit configured to determine a new travel route when the veering detecting unit detects the veering of the mobile object,

wherein the travel route determination unit employs the detection result obtained by the veering detecting unit to determine a new travel route based on one or more of route determination conditions.

2. The route provision apparatus as claimed in claim 1, wherein the veering detecting unit detects a veering state in which the mobile object has veered away from the determined travel route, and

wherein the travel route determination unit employs the veering state to select one of the route determination conditions to determine a new travel route.

3. A navigation system comprising:

a position acquisition unit configured to obtain current positioning data including information of a current position of a mobile object;

a veering detecting unit configured to employ the current positioning data to detect a veering of the mobile object from a determined travel route;

a travel route determination unit configured to determine a new travel route when the veering detecting unit detects the veering of the mobile object; and

a display device configured to display the determined travel route,

wherein the travel route determination unit employs the detection result obtained by the veering detecting unit to determine a new travel route based on one or more of route determination conditions.

4. The navigation system as claimed in claim 3, wherein the veering detecting unit detects a veering state in which the mobile object has veered away from the determined travel route, and

wherein the travel route determination unit employs the veering state to select one of the route determination conditions to determine a new travel route.

5. A route provision method comprising:

obtaining current positioning data including information of a mobile object;

employing the current positioning data to detect a veering of the mobile object from a determined travel route; and

determining a new travel route when the veering of the mobile object from the determined travel route is detected,

wherein in the determining of the new travel route, the detection result obtained at the detecting of the veering are employed to determine a new travel route based on one or more of route determination conditions.

6. The route provision method as claimed in claim 5, wherein in the detecting of the veering, a veering state in which the mobile object has veered away from the determined travel route is detected, and

wherein in the determining of the travel route, the veering state is employed to select one of the route determination conditions to determine a new travel route.

7. A computer program product for causing a computer to execute procedures, comprising:

means for obtaining current positioning data including information of a mobile object;

means for employing the current positioning data to detect a veering of the mobile object from a determined travel route; and

means for determining a new travel route when the veering of the mobile object from the determined travel route is detected,

wherein the means for determining of the new travel route employs the detection result obtained at the detecting of the veering to determine a new travel route based on one or more of route determination conditions.

8. The computer program product as claimed in claim 7, wherein the means for detecting the veering detects a veering state in which the mobile object has veered away from the determined travel route, and

wherein the means for determining the travel route employs the veering state to select one of the route determination conditions to determine a new travel route.

9. The computer program product as claimed in claim 7 further comprising means for displaying the determined travel route.
