Abstract

A user selects route preferences related to weighing or considering different factors when determining a requested candidate route to a destination and chooses a candidate route ranking. A motor vehicle detects a condition associated with a vehicle state. The motor vehicle displays the candidate route based on the detected vehicle condition in a preselected order determined by the route ranking.

determining a vehicle state associated with the detected vehicle operating condition;

displaying the determined candidate routes in a preselected order determined by the received ranking;

wherein all of the determined candidate routes are displayed on the display device when a first vehicle state is determined; and

wherein only a first ranked determined candidate route is displayed on a display device of the motor vehicle when a second vehicle state is determined.

2. The method according to claim 1, wherein the at least one route preference includes a preference that optimizes or minimizes energy consumption.

3. The method according to claim 1, wherein the plurality of candidate routes include a first candidate route that optimizes or minimizes energy consumption, a second candidate route that optimizes or minimizes travel time, and a third candidate route that optimizes or minimizes travel distance.

4. The method according to claim 1, wherein the step of detecting the at least one vehicle operating condition further includes receiving a signal associated with a speed of the motor vehicle from a sensor;

and

wherein the step of determining the vehicle state associated with the detected vehicle operating condition further includes determining whether the motor vehicle is moving or stopped.

5. The method according to claim 4, wherein the first vehicle state is associated with a stopped motor vehicle and the second vehicle state is associated with a moving motor vehicle.

6. The method according to claim 1, wherein the navigation system automatically displays only navigation information associated with the first ranked determined candidate route on the display device when the second vehicle state is determined.

7. The method according to claim 1, further comprising:

receiving a selection of one of the determined candidate routes displayed on the display device when the first vehicle state is determined; and

displaying navigation information associated with the selected one of the determined candidate routes on the display device.

8. A method of displaying a route on a display device of a navigation system in a motor vehicle, comprising the steps of:

requesting navigation information associated with multiple candidate routes from a current location of a motor vehicle to a destination;

receiving a ranking associated with the multiple candidate routes from a user;

receiving the navigational information associated with the multiple candidate routes from a remote location;

ordering the received multiple candidate routes in a preselected order according to the ranking, wherein a first ranked candidate route is ranked higher than a second ranked candidate route;

receiving a signal associated with at least one vehicle condition from a sensor;

determining a vehicle state based on the received signal;

displaying the received multiple candidate routes on a display device associated with the navigation system in the preselected order;

wherein when a first vehicle state is determined, the first ranked candidate route and the second ranked candidate route are displayed on the display device; and

wherein when a second vehicle state is determined, the first ranked candidate route is displayed on the display device and any remaining candidate routes are not displayed on the display device.

9. The method according to claim 8, wherein the step of displaying the received multiple candidate routes further includes displaying a higher ranked candidate route with a more distinctive indicia than a lower ranked candidate route.

10. The method according to claim 8, wherein the at least one vehicle condition comprises at least one of a vehicle operating condition and an environmental characteristic of the motor vehicle.

11. The method according to claim 8, further comprising:

displaying a route comparison on the display device, wherein the route comparison includes a display of the difference between information associated with two or more of the candidate routes.

12. The method according to claim 8, wherein the first vehicle state is associated with a stopped motor vehicle and the second vehicle state is associated with a moving motor vehicle.

13. The method according to claim 12, wherein the navigation system automatically displays only navigation information associated with the first ranked determined candidate route on the display device when the second vehicle state is determined.

14. The method according to claim 8, further comprising:

receiving an updated candidate route at the motor vehicle;

wherein the updated candidate route includes changes to the determined candidate route that exceed a threshold.

15. The method according to claim 8, further comprising:

displaying a savings message on the display device, the savings message displaying the difference between information associated with at least two of the multiple candidate routes.

16. The method according to claim 15, wherein the savings message indicates the difference between at least one of energy consumption, travel time, and travel distance associated with at least two of the multiple candidate routes.

17. The method according to claim 8, further comprising:

displaying an HOV icon associated with any of the multiple candidate routes that include at least one carpool lane.
