Abstract
A method for accelerating reprocessing of a navigation route to update the navigation route includes the procedures of (1) activating reprocessing, (2) comparing route nodes, (3) integrating the navigation routes, (4) updating the navigation route. The method does not have to repeat the entire navigation process occurred to the conventional navigation system and can rapidly update the new navigation route.
Claims7
A method for accelerating reprocessing of a navigation route, comprising the steps of:
- (1) activating reprocessing:
- keeping data of an original navigation route and activating process for a new navigation route when a vehicle deviates from the original navigation route;
- (2) comparing route nodes:
- processing the new navigation route from a start point where the vehicle is located, comparing with nodes of the original navigation route when passing each new node;
- (3) integrating the navigation routes:
- comparing the nodes until a same node is found, stopping process of the new navigation route beyond the same node, and replicating the rest of original navigation route beyond the same node to the new navigation route to form a new route;
- and
- (4) updating the navigation route:
- changing the integrated new route to become the navigation route and ending the process.

A method for accelerating reprocessing of a navigation route, comprising the steps of:
- (1) activating reprocessing:
- keeping data of an original navigation route and activating process for a new navigation route when a vehicle deviates from the original navigation route;
- (2) marking an interim destination:
- a navigation system finding out a node that is nearer to the original navigation route based on the current vehicle location and designating the found node as an interim destination;
- (3) processing an interim navigation route:
- the navigation system processing and deriving an interim navigation route between the current vehicle location and the interim destination;
- (4) integrating the navigation routes:
- stopping process of the route beyond the interim destination, and replicating the rest of original navigation route beyond interim destination to the new navigation route to form a new route;
- and
- (5) updating the navigation route:
- changing the integrated new route to become the new navigation route and ending the process.
