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;
veering detecting unit configured to employ the current positioning data to detect a veering state in which the mobile object has veered from a determined travel route,wherein the determined travel route has a destination; and
a travel route determination unit configured to select a route determination condition from among a plurality of route determination conditions based on the veering state, and to determine a new travel route based on the selected route determination condition, when the veering detecting unit detects the veering of the mobile object,wherein the plurality of route determination conditions include;
a return route search condition for determining the new travel route from the current position to a specific point along the determined travel route;
a first revised route search condition for determining the new travel route from the current position to the destination; and
a second revised route search condition for determining the new travel route from the current position to the destination.

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.

12. A navigation apparatus, comprising:
-
a positioning circuit that outputs positioning data indicating a current position of a mobile object; and a control circuit that determines when the mobile object veers from a previously determined route, wherein, when a veering of the mobile object has a first characteristic, the control circuit determines a new travel route from the current position to a specific point along the previously determined route other than a destination of the previously determined route, wherein, when the veering of the mobile object has a second characteristic, the control circuit determines the new travel route from the current position to the destination based on a first route determination condition; and wherein, when the veering of the mobile object has a third characteristic, the control circuit determines the new travel route from the current position to the destination based on a second route determination condition. - View Dependent Claims (13, 14, 15, 16, 17, 18)
