Systems and methods for a navigational device with improved route calculation capabilities
First Claim
1. An electronic navigational aid device with route calculation capabilities, comprising:
- a processor;
a memory adapted to communicate with the processor, the memory having cartographic data and a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types;
a display connected to the processor and capable of displaying the cartographic data;
wherein the device is adapted to calculate a route to navigate to the desired destination; and
wherein the device is adapted to adjust a starting point for the route calculation to an appropriate location such that the device is on the route at a time when the route calculation is completed.

Abstract
Systems, devices and methods are provided for an improved navigational route planning device which provides more understandable, accurate and timely route calculation capabilities. The navigational aid device with route calculation capabilities includes a processor connected to a memory. The memory includes cartographic data and a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types. A display is connected to the processor and is capable of displaying the cartographic data. The device is adapted to calculate a route to navigate to the desired destination. And, the device is adapted to adjust a starting point for the route calculation to an appropriate location such that the device is on the route at a time when the route calculation is completed. The device processes travel along the route, recognizes when the device has deviated from the route, and calculates a new route to navigate to the desired destination.

23. A navigation system, comprising:
-
a mass data storage adapted to store navigation data;
a server having a processor and memory, wherein the server is adapted to communicate with the mass data storage; and
a navigation device adapted to communicate with and retrieve navigation data from the server via a communication channel, wherein the navigation device includes;
a processor;
a display connected to the processor; and
a memory connected to the processor, the memory having cartographic data and a route to a desired destination stored therein, the cartographic data including data indicative of thoroughfares of a plurality of types;
wherein the system processes the navigation device'"'"'s travel along the route;
wherein the system recognizes when the device has deviated from the route and is adapted to calculate a new route to navigate the device to the desired destination using an exchange of data, via the communication channel, between the server, the mass storage device and the navigation device; and
wherein the system is adapted to adjust a starting point for the new route calculation to an appropriate location such that the device is on the new route at a time when the route calculation is completed. - View Dependent Claims (24, 25, 26, 27, 28)
