Abstract

A method includes directing a vehicle to take a route designated as a preferred route from among a plurality of potential routes. The designation as a preferred route is based in part on a predicted energy recovery from a regenerative shock absorber when the vehicle traverses the preferred route. A system includes a processor that executes a program designating at least one preferred route from among a plurality of potential routes. The designating is based in part on a predicted energy recovery from a regenerative shock absorber, and a transmitter that communicates the at least one preferred route to a vehicle.

Claims

1. A route selection method, comprising:

directing a vehicle to take a route designated as a preferred route from among a plurality of potential routes, the designation as a preferred route based in part on a predicted energy recovery from at least one regenerative shock absorber when the vehicle traverses the preferred route, the predicted energy recovery based in part on a measured energy recovery from a regenerative shock absorber of at least one crowd vehicle that traversed at least some of the plurality of potential routes, the measured energy recovery stored within a crowd sourced data storage module.

2. The route selection method of claim 1, wherein the predicted energy recovery is adjusted based on a speed at which the at least one crowd vehicle previously traversed the preferred route.

3. The route selection method of claim 1, wherein the predicted energy recovery is adjusted based in part on degradation of the at least one regenerative shock absorber in the vehicle, degradation of the regenerative shock absorber in the at least one crowd vehicle that previously traversed the preferred route, or both.

4. The route selection method of claim 1, wherein a predicted net energy consumption for the vehicle is associated with each of the plurality of potential routes, the predicted net energy consumption for the preferred route less than the predicted net energy consumption for each of the other routes in the plurality of potential routes.

5. The route selection method of claim 1, further comprising estimating the predicted energy recovery from the at least one regenerative shock absorber for each of the plurality of potential routes.

6. The route selection method of claim 1, wherein the predicted energy recovery from the at least one regenerative shock absorber when the vehicle traverses the preferred route is estimated by adding the measured energy recovery from the regenerative shock absorber of the at least one crowd vehicle when traversing a first route segment of the preferred route to the measured energy recovery from the regenerative shock absorber of the at least one crowd vehicle when traversing a second route segment of the preferred route.

7. The route selection method of claim 6, wherein the first route segment and the second route segment each extend between street intersections along the preferred route.

8. The route selection method of claim 1, wherein the predicted energy recovery is based on a plurality of the measured energy recoveries for previous drives along the preferred route.

9. The route selection method of claim 8, wherein the predicted energy recovery is an average of more than one measured energy recovery.

10. The route selection method of claim 8, wherein the crowd sourced data storage module is cloud based.

11. The route selection method of claim 1, wherein the measured energy recovery is collected by at least one shock absorber sensors during previous traversals of the preferred route by the at least one crowd vehicle.

12. The route selection method of claim 1, wherein the predicted energy recovery is communicated to the vehicle from a cloud server.

13. The route selection method of claim 1, wherein the preferred route comprises a plurality of preferred routes, and further comprising displaying the plurality of preferred routes as optional routes for selection by an operator of the vehicle.

14. The route selection method of claim 1, further comprising additionally basing the designating on an operator preference for a smoother route with less energy recovery from the at least one regenerative shock absorber or a bumpier route with more energy recovery from the at least one regenerative shock absorber.

15. A route selection system, comprising:

a processor that executes a program designating at least one preferred route from among a plurality of potential routes, the designating based in part on a predicted energy recovery from at least one regenerative shock absorber;

a transmitter that communicates the at least one preferred route to a vehicle; and

a crowd sourced data storage module that stores information corresponding to measured energy recoveries from regenerative shock absorbers of at least one crowd vehicle that traversed at least some of the plurality of potential routes.

16. The route selection system of claim 15, wherein the predicted energy recovery is based on the information stored in the crowd sourced data module.

17. The route selection system of claim 15, wherein the information corresponding to measured energy recoveries from regenerative shock absorbers is provided by accelerometers of the at least one crowd vehicle.

18. A route selection system, comprising:

a crowd sourced data storage module that stores information corresponding to measured energy recoveries from regenerative shock absorbers of at least one crowd vehicle that traversed at least some of a plurality of potential routes; and

a processor that executes a program designating at least one preferred route from among the plurality of potential routes based in part on the measured energy recoveries.

19. The route selection system of claim 18, wherein the crowd sourced data storage module is at least partially cloud based.

20. The route selection system of claim 19, further comprising a transmitter that communicates the at least one preferred route to a vehicle.
