Abstract
A vehicle navigation system for providing route guidance in response to an input destination. The navigation system comprises a position sensing unit for sensing the location of the vehicle, a user input device for entering preferred route criteria and the desired destination, a display for outputting route guidance information, a controller, and a machine learning unit. The machine learning unit communicates with the controller and the user input, and monitors the user-selected preferred route criteria during a learning phase. Once the preferred route criteria have been learned, the machine learning unit enters an intervention phase whereby inferred user-preferred route criteria is transmitted directly to the controller. In this manner, users need not enter preferred route criteria upon each navigation sequence.
