Abstract
A vehicle route guidance system considers driver preferences, vehicle parameters such as speed and performance capabilities in a navigation computer, and outputs flexible guidance instructions based on these considerations. The system monitors vehicle parameters such as current location and speed with sensors such as an odometer (109), a compass (115), and a GPS receiver (113). The system also determines the location of a vehicle maneuver and then, considering the former attributes with a model free mechanism, in this case a navigation computer with fuzzy inferencing (101), communicates to the driver instructing him how to manoeuver.
Claims6
A vehicle route guidance system comprising:
- means for sensing vehicle location;
- means for determining a location of an anticipated vehicle manoeuvre;
- means for comparing said sensed vehicle location and said determined location and generating a distance difference corresponding to a difference between the vehicle location and the location of the anticipated vehicle manoeuvre;
- means for providing driver instruction timing preferences in accordance with the generated distance difference, wherein the driver instruction timing preferences are comprised of a plurality of continuous functions;
- means, responsive to said generated distance difference, for determining a degree of conformance to the driver instruction timing preferences, and for generating a guidance instruction whose timing is determined by the degree of conformance to the driver instruction timing preferences;
- and
- means for communicating said guidance instruction to a driver of the vehicle.
A route guidance system for a vehicle, the system comprising:
- means for determining a location of the vehicle;
- means for determining a speed of the vehicle;
- means for determining a location of an anticipated manoeuvre of the vehicle;
- means for generating a distance difference corresponding to a difference between the location of the vehicle and the location of the anticipated manoeuvre of the vehicle;
- first means for driver preference matching for providing a distance attribute and a speed attribute dependent on the distance difference and the determined speed of the vehicle respectively;
- second means for driver preference matching for providing a manoeuvre announcement timing preference score dependent on both of the provided speed and distance attributes;
- and
- means for generating a guidance instruction, the timing determined dependent on the manoeuvre announcement timing preference score.
