Abstract

A method of advising a driver of a vehicle may include at a computing system, receiving from the vehicle a predicted energy usage request for a selected route. In response to the request, the method may further include transmitting for each of a plurality of segments defining the selected route, an energy usage estimate based on data indicative of propulsive energy previously used by vehicles to travel the segments and to travel other segments having common characteristics with the segments.

Claims

1. A method of advising a driver of a vehicle comprising:

at a computing system,

receiving from a vehicle a predicted energy usage request for a selected route; and

in response to the request, transmitting for each of a plurality of segments defining the selected route, an energy usage estimate based on data indicative of propulsive energy previously used by vehicles to travel the segments and to travel other segments having common characteristics with the segments.

2. The method of claim 1 wherein the common characteristics include speed limit, road grade, expected number of stops, geographical location, direction of travel, traffic density, or road length.

3. The method of claim 1 further comprising, at the computing system, in response to the request, transmitting for each of a plurality of segments defining the selected route, an energy usage estimate based on data indicative of propulsive energy previously used by the vehicle to travel the segments and to travel other segments having common characteristics with the segments.

4. The method of claim 1 wherein the data indicative of propulsive energy includes battery power consumed, miles per gallon, miles per gallon equivalent, joules per kilometer, watt-hours per kilometer, or liters per kilometer.

5. The method of claim 1 further comprising, at a computing system, tagging the propulsive energy previously used by the vehicle to travel the plurality of segments with an identifier of the driver of the vehicle and the vehicle.

6. The method of claim 1 wherein the selected route is at least one of an ordered set of road segments and an unordered set of geographically constrained road segments.

7. The method of claim 3 wherein the energy usage estimate is a weighted average of the propulsive energy previously used by vehicles to travel the segments and to travel other segments having common characteristics with the segments and the propulsive energy previously used by the vehicle to travel the segments and to travel other segments having common characteristics with the segments.

8. A vehicle navigation system comprising:

at least one controller programmed to

transmit to an off-vehicle computing arrangement an energy usage request for a selected route;

receive, in response to the request, an energy usage estimate for each of a plurality of segments defining the selected route from the arrangement, wherein the estimate is based on data indicative of propulsive energy previously used by vehicles to travel the segments and to travel other segments having common characteristics with the segments; and

output the estimate for display.

9. The vehicle navigation system of claim 8 wherein the request identifies a type of the vehicle and wherein the vehicles are of a same type as the vehicle.

10. The vehicle navigation system of claim 8 wherein the request identifies a driving style of a driver of the vehicle and wherein the vehicles have drivers with common characteristics as the driver of the vehicle.

11. The vehicle navigation system of claim 8 wherein the at least one controller is further programmed to transmit to the off-vehicle computing arrangement data indicative of propulsive energy used by the vehicle to travel segments of routes.

12. The vehicle navigation system of claim 8 wherein the estimate includes distance to empty data, energy consumption efficiency, or rate of energy consumption data.

13. The vehicle navigation system of claim 8 wherein the vehicle is one of the vehicles.

14. The vehicle navigation system of claim 8 wherein the estimate is further based on a mass of the vehicle, a type of the vehicle, or an expected speed of the vehicle.

15. A method of advising a driver of a vehicle comprising:

transmitting to an off-vehicle computing arrangement an energy usage prediction request for a selected route;

receiving, in response to the request, an energy usage prediction for each of a plurality of segments defining the selected route from the arrangement, wherein the prediction is based on data indicative of propulsive energy previously used by vehicles to travel the segments and to travel other segments having common characteristics with the segments; and

outputting the prediction for display.

16. The method of claim 15 wherein the request identifies a type of the vehicle and wherein the vehicles are of a same type as the vehicle.

17. The method of claim 15 wherein the request identifies a driving style of a driver of the vehicle and wherein the vehicles have drivers with a same driving style as the driver of the vehicle.

18. The method of claim 15 further comprises transmitting to the off-vehicle computing arrangement data indicative of propulsive energy used by the vehicle to travel segments of routes.

19. The method of claim 15 wherein the prediction includes distance to empty data or rate of energy consumption data.

20. The method of claim 15 wherein the vehicle is one of the vehicles.
