Patent Images
1. A vehicle navigation system for providing route guidance in response to an input destination comprising:
- a position sensing unit for sensing the location of the vehicle;
a user input device for entering preferred route criteria and said destination;
a display for outputting route guidance information;
a controller arranged in communication with said position sensing unit, user input and display, said controller including a route calculator for performing a route search from the sensed vehicle location to said destination in accordance with said preferred route criteria, and outputting route guidance information to said display; and
a machine learning unit in operative communication with said controller and said user input, said machine learning unit monitoring said preferred route criteria input from said user input during a learning phase and transmitting inferred user-preferred route criteria to said controller during an intervention phase.

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.

18. A method of inferring user preferences for a vehicle navigation system comprising a position sensing unit, a user input device, a display, a controller and a machine learning unit, the method comprising the steps of:
-
monitoring, with said machine learning unit, preferred route criteria input from said user input and transmitted to said controller during a learning phase; and
, thereafter,entering an intervention phase wherein inferred route criteria is transmitted to said controller in response to an input destination. - View Dependent Claims (19, 20)
