Multiple navigation routes based on user preferences and real time parameters
First Claim
Patent Images
1. A navigation system for a vehicle that provides routing information while traversing a route, comprising:
- a data processor having a database of routing information over which a land vehicle may travel, the data processor being programmable with a starting point and a destination point, the data processor being provided with user preference data, the data processor being provided with realtime parameters that are used in providing previously selected route between the starting point and the destination point that is selected prior to beginning traversing the route;
a global positioning system (GPS) providing a set of current location data corresponding to the current location of the vehicle;
the data processor providing an alternative route to the destination point based upon the set of current location data, user preference data and a set of updated realtime parameters that provides the user with the alternative route while traversing the previously selected route.

Abstract
A navigation system and method incorporating the use of a navigation system that provides alternate routes to an initially selected route based upon updated, real time parameters. The system is provided with user preference data that is used when developing the initial route and alternate routes. The system may be programmed to only provide alternate routes if a predetermined improvement in efficiency is potentially available.

5. A method of navigating to a destination utilizing a data processing system:
-
inputting a starting location;
inputting a destination location;
inputting a set of real time parameters;
inputting a set of user preferences;
calculating at least one route from the staring point to the destination including factoring in the effect of the real time parameters and user preferences;
selecting one of the routes and traveling along a selected route toward the destination;
updating the set of real time parameters to create an updated set of real time parameters while traveling along the selected route;
calculating an alternate route from an intermediate location to the destination location based upon the updated set of real time parameters;
comparing the selected route to the alternate route; and
providing information to driver to evaluate and choose between the selected route and the alternate route, the choice of the driver thereafter being the selected route for the continuation of traveling to the destination location. - View Dependent Claims (6, 7, 8, 9, 10, 11)
