Abstract

An illustrative example system includes a user interface configured to provide information to an individual in a vehicle. A controller is configured to estimate a remaining power capacity of a source of electric power that will remain after travelling along an identified route to an identified destination. The controller determines whether the estimated remaining power capacity will be sufficient for travelling from the identified destination to at least one known location where increasing the power capacity of the source is possible. The user interface provides an indication of at least one recommendation regarding increasing the power capacity of the source prior to reaching the identified destination when the estimated remaining power capacity will not be sufficient for travelling from the identified destination to the at least one known location.

Claims

1. A method, comprising:

determining an estimated remaining power capacity of a vehicle source of electric power that will remain after travelling along an identified route to an identified destination for each of a plurality of driving modes including a current driving mode;

determining whether any of the estimated remaining power capacities will be sufficient for travelling from the identified destination to at least one known location where increasing the power capacity of the vehicle source of electric power is possible; and

providing an indication of at least one recommendation regarding the remaining power capacity of the vehicle source of electric power prior to reaching the identified destination when the estimated remaining power capacity for the current driving mode will not be sufficient for travelling from the identified destination to the at least one known location, the at least one recommendation including an indication prompting a driver to use one of the plurality of drive modes different from the current driving mode that results in an estimated remaining power capacity that is sufficient for travelling from the identified destination to the at least one known location.

2. The method of claim 1, comprising

identifying at least one recommended location where increasing the power capacity prior to reaching the identified destination is possible;

and

providing automated route guidance to the recommended location based on a selection by a user.

3. The method of claim 2, wherein the at least one recommended location is on the identified route.

4. The method of claim 2, wherein the at least one recommended location is near a portion of the identified route.

5. The method of claim 1, wherein estimating the remaining power capacity is based on at least one characteristic of the identified route, the at least one characteristic having an impact on electrical energy use.

6. The method of claim 5, wherein the at least one characteristic comprises

a distance to the identified destination along the identified route, and

at least one of:

a change in elevation along the identified route,

a traffic condition along the identified route, and

a weather condition along the identified route.

7. The method of claim 1, wherein estimating the remaining power capacity is based on power consumption information obtained during at least one previous journey along at least a portion of the identified route.

8. The method of claim 1, wherein providing the indication includes providing a warning that there may be insufficient power capacity to travel to the at least one known location after arriving at the identified destination if additional power capacity is not obtained prior to reaching the identified destination.

9. The method of claim 1, wherein the plurality of driving modes includes at least a sport mode and an economy mode.

10. The method of claim 1, further comprising the step of identifying the route by recognizing the route based on previous vehicle travels along at least a portion of the identified route.

11. A vehicle comprising a system configured to perform the method of claim 1.

12. A system, comprising:

user interface means for providing information to an individual in a vehicle; and

control means for

determining an estimated remaining power capacity of a vehicle source of electric power that will remain after travelling along an identified route to an identified destination for each of a plurality of driving modes including a current driving mode;

determining whether any of the estimated remaining power capacities will be sufficient for travelling from the identified destination to at least one known location where increasing the power capacity of the vehicle source of electric power is possible; and

providing an indication of at least one recommendation regarding the remaining power capacity of the vehicle source of electric power prior to reaching the identified destination when the estimated remaining power capacity for the current driving mode will not be sufficient for travelling from the identified destination to the at least one known location, the at least one recommendation including an indication prompting a driver to use one of the plurality of drive modes different from the current driving mode that results in an estimated remaining power capacity that is sufficient for travelling from the identified destination to the at least one known location.

13. The system of claim 12, wherein

the user interface means includes at least one of a display screen and a speaker;

and

the control means includes at least one computing device and memory associated with the at least one computing device.

14. The system of claim 13, wherein the at least one computing device comprises

a first processor configured to determine information regarding the identified route and the at least one known location;

and

a second processor configured to determine the estimated remaining power capacity.

15. The system of claim 12, wherein the control means is configured for

identifying at least one recommended location where increasing the power capacity prior to reaching the identified destination is possible;

and

providing automated route guidance to the recommended location based on a selection by a user.

16. The system of claim 15, wherein the at least one recommended location is on the identified route or near a portion of the identified route.

17. The system of claim 12, wherein the control means is configured for estimating the remaining power capacity based on at least one characteristic of the identified route, the at least one characteristic having an impact on electrical energy use.

18. The system of claim 17, wherein the at least one characteristic comprises

a distance to the identified destination along the identified route and

at least one of:

a change in elevation along the identified route,

a traffic condition along the identified route, and

a weather condition along the identified route.

19. The system of claim 12, wherein the control means is configured for providing a warning that there may be insufficient power capacity to travel to the at least one known location after arriving at the identified destination if additional power capacity is not obtained prior to reaching the identified destination.

20. The system of claim 12, wherein the control means is configured for estimating the remaining power capacity based on power consumption information obtained during at least one previous journey along at least a portion of the identified route.

21. The system of claim 20, wherein a current location of the vehicle, a trajectory, and a time of day for the identified route correspond to the previous journey.

22. The system of claim 12, wherein the plurality of driving modes includes at least a sport mode and an economy mode.

23. The system of claim 12, wherein the control means is configured for identifying the route by recognizing the route based on previous vehicle travels along at least a portion of the identified route.

24. The system of claim 14, wherein the control means is configured to determine a preference of the individual in response to the individual'"'"'s override of any automatic control of an energy consuming vehicle system.

25. A vehicle comprising the system of claim 12.

26. A system, comprising:

a user interface including at least one of a display and a speaker, the user interface providing information to an individual in a vehicle; and
