Abstract

A vehicle alert system may include a controller configured to receive a waypoint and a current vehicle energy, determine a route to the waypoint and vehicle energy necessary to accomplish the route, receive waypoint information indicative of non-driving energy consumption associated with the waypoint, and generate an adjustment factor based on the non-driving energy consumption. The controller may further be configured to attribute the adjustment factor to the vehicle energy necessary to accomplish the route, determine whether the attributed vehicle energy exceeds the current vehicle energy, and issue an alert in response to the attributed vehicle energy exceeding the current vehicle energy.

Claims

1. A vehicle alert system comprising:

a controller configured to receive waypoint information indicative of non-driving energy consumption associated with a waypoint, to modify an estimate of vehicle energy necessary to travel to the waypoint based on the non-driving energy consumption to generate a modified estimate, and to issue an alert in response to the modified estimate exceeding a current vehicle energy.

2. The system of claim 1, wherein the modified estimate includes energy necessary to drive from the waypoint to a next closest energy station.

3. The system of claim 1, wherein the waypoint information includes one of predicted and measured non-driving vehicle activity associated with the waypoint.

4. The system of claim 1, wherein the waypoint information includes a length of stay at the waypoint.

5. The system of claim 4, wherein the waypoint information includes an expected average ambient temperature at the waypoint during the length of the stay.

6. The system of claim 1, wherein the current vehicle energy includes at least one of fuel energy and battery energy.

7. A vehicle alert method comprising:

by a controller,

receiving a waypoint and a current energy level,

classifying the waypoint based on waypoint attributes indicative of potential non-driving energy consumption at the waypoint,

generating an adjustment factor based on the potential non-driving energy consumption,

modifying the current energy level by the adjustment factor, and

issuing an alert in response to the modified energy level exceeding the current energy level.

8. The method of claim 7, wherein the waypoint attributes include non-driving vehicle activity associated with the waypoint.

9. The method of claim 7, wherein the waypoint attributes include a length of stay at the waypoint.

10. The method of claim 9, wherein the waypoint attributes include an expected average ambient temperature at the waypoint during the length of the stay.

11. The method of claim 7, wherein the current energy level includes at least one of fuel energy and battery energy.

12. The method of claim 9 further comprising determining a distance between the waypoint and a next closest charge station.

13. The method of claim 12, wherein the adjustment factor is further generated based on the distance.

14. A vehicle comprising:

an interface; and

a controller configured to, in response to an indication of expected non-driving energy consumption at a destination for the vehicle, issue an alert via the interface provided an estimate of vehicle energy necessary to travel to the drive cycle destination that is based on the expected non-driving energy consumption exceeds a current vehicle energy.

15. The vehicle of claim 14, wherein the expected non-driving energy consumption includes an amount of energy necessary to leave the destination and reach a charge station.

16. The vehicle of claim 14, wherein the current energy includes at least one of fuel energy and battery energy.

17. The vehicle of claim 14, wherein the expected non-driving energy consumption is an expected average energy consumption at the destination.
