Abstract:
1. A method of intelligent navigation of a vehicle using a navigation system with artificial intelligence, said method comprising the steps of: maintaining a map in an information database associated with the navigation system of the vehicle, wherein navigation system includes a global positioning means, a navigation means, and a controller, and the map includes a location of a traffic control device; sensing a location of the vehicle using an input means in communication with the navigation system; determining when the sensed vehicle location is identifiable on the map maintained by the information database and updating the map using the sensed vehicle location when not identifiable; determining when the vehicle is approaching an identifiable traffic control device using the map in the information database and the sensed vehicle location, when the sensed vehicle location is identifiable; adaptively updating the map in the information database with a potential presence of a traffic control device by determining when the vehicle is slowing or stopped, when determined that the vehicle is not approaching an existing identifiable traffic control device on the map in the information database; and transmitting an alert message that the vehicle is approaching the identifiable traffic control device, when determined that the vehicle is approaching the identifiable traffic control device on the map in the information database, wherein adaptively updating the map in the information database further comprises: determining when the vehicle is stopped at the location of the vehicle, using the map in the information database to determine if the vehicle has previously stopped at the location, and updating the map in the information database that location has a stoplight, when the vehicle has not previously stopped at the identified vehicle location, and updating the map in the information database that the location may have a stoplight or stop sign, when the vehicle has previously stopped at the location.
