Abstract

A system for use on a vehicle includes a user interface, such as a display and a speaker. A controller determines a remaining power capacity of a vehicle electrical power source and a required power capacity to travel along an identified route to an identified destination based on at least one characteristic of the identified route, which has an effect on electrical power use. The controller determines when a relationship between the remaining power capacity and the required power capacity satisfies at least one predetermined criterion. The system provides an indication of options based on at least one of the remaining power capacity, the determined relationship, or the predetermined criterion. The options may include an alternative route that consumes less power and an alternative destination where power is available for the electrical power source.

a change in elevation along at least a portion of the identified route,

a traffic condition along at least a portion of the identified route, and

a weather condition along at least a portion of the identified route.

5. The method of claim 1, wherein the at least one characteristic of the identified route comprises at least one of

a change in elevation along at least a portion of the identified route,

a traffic condition along at least a portion of the identified route,

a weather condition along at least a portion of the identified route, and

a remaining distance along the identified route.

6. The method of claim 5, wherein

the alternative route has at least one alternative characteristic that has an effect on electrical power use, the at least one alternative characteristic resulting in less electrical power use;

and

the at least one alternative characteristic comprises at least one of

a change in elevation along at least a portion of the alternative route,

a traffic condition along at least a portion of the alternative route,

a weather condition along at least a portion of the alternative route, and

a distance along the alternative route.

7. The method of claim 1, comprising

determining a location of at least one alternative destination where power is available to provide additional charge to the electrical power source of the vehicle;

providing an indication regarding the determined location; and

providing automated route guidance to the determined location based on a user selection of the at least one alternative destination.

8. The method of claim 1, comprising

identifying at least one vehicle system that utilizes electrical power;

and

automatically altering operation of the at least one vehicle system in a manner that reduces an amount of electrical power utilized by the at least one vehicle system.

9. The method of claim 8, comprising

identifying a plurality of vehicle systems that utilize electrical power;

and

determining an order in which to automatically alter operation of at least two of the plurality of vehicle systems.

10. The method of claim 9, comprising

identifying user a preference regarding an order in which operation of the plurality of vehicle systems should be automatically altered;

and

selecting an order in which to automatically alter operation of at least two of the plurality of vehicle systems based on the identified user preference.

11. The method of claim 8, wherein

a user can override the automatically altered operation;

and

the method comprises

providing an indication regarding an expected impact on an ability to reach the identified destination resulting from the user overriding the automatically altered operation.

12. The method of claim 1, comprising providing automated route guidance along the identified route to the identified destination based on the user not selecting any of the provided options.
