Abstract

A method includes: receiving, by a controller of a vehicle, operation data indicative of a duty cycle for the vehicle, wherein the duty cycle is a substantially repeatable set of vehicle or vehicle component operations for a particular event or for a predefined time period; identifying, by the controller, a desired vehicle duty cycle from a population of vehicle duty cycles based on the operation data indicative of the duty cycle for the vehicle and on a desired operating parameter of the vehicle; receiving, by the controller, a set of trim parameters that are electronic operational parameters associated with the desired vehicle duty cycle; and controlling, by the controller, one or more operating points of the vehicle based on the set of trim parameters.

First claim

What is claimed is:

1. An apparatus, comprising:
a trim parameter circuit structured to receive a set of default trim parameters that are electronic operational parameters that control one or more operating points of a vehicle component or system; and
a vehicle duty cycle circuit coupled to the trim parameter circuit, the vehicle duty circuit structured to:
receive operation data indicative of a duty cycle for the vehicle, wherein the duty cycle is a substantially repeatable set of vehicle or vehicle component operations for a particular event or for a predefined time period;
identify a desired vehicle duty cycle from a population of vehicle duty cycles based on the operation data indicative of the duty cycle for the vehicle and on a desired operating parameter of the vehicle;
receive a set of trim parameters associated with the desired vehicle duty cycle; and
control the one or more operating points of the vehicle component or system in accordance with the set of trim parameters.

2. The apparatus of claim 1 , wherein the operation data indicative of the duty cycle for the vehicle includes an acceleration characteristic of the vehicle or an aerodynamic speed of the vehicle.

3. The apparatus of claim 1 , further comprising an operator interface circuit structured to provide the set of trim parameters to an operator input/output device of the vehicle and responsive to receiving an affirmative implementation instruction from the operator input/output device, instruct the vehicle duty circuit to apply the set of trim parameters with the vehicle.

4. The apparatus of claim 1 , wherein the vehicle duty cycle circuit is further structured to apply one or more boundaries for the received operation data and sample the received operation data at a predefined frequency for a predefined period of time to determine a vehicle duty cycle for the vehicle.

5. The apparatus of claim 4 , wherein the vehicle duty cycle circuit is structured to use a hierarchical clustering process to define the one or more boundaries and to sample the received operation data to determine the vehicle duty cycle.

6. The apparatus of claim 1 , wherein the desired operating parameter is to minimize fuel consumption for the vehicle.

7. The apparatus of claim 1 , wherein the desired operating parameter is to incrementally improve fuel economy for the vehicle.

8. A method, comprising:
receiving, by a controller of a vehicle, operation data indicative of a duty cycle for the vehicle, wherein the duty cycle is a substantially repeatable set of vehicle or vehicle component operations for a particular event or for a predefined time period;
identifying, by the controller, a desired vehicle duty cycle from a population of vehicle duty cycles based on the operation data indicative of the duty cycle for the vehicle and on a desired operating parameter of the vehicle;
receiving, by the controller, a set of trim parameters that are electronic operational parameters associated with the desired vehicle duty cycle; and
controlling, by the controller, one or more operating points of the vehicle based on the set of trim parameters.

9. The method of claim 8 , further comprising receiving, by the controller, additional data indicative of another duty cycle for the vehicle and determining a different vehicle duty cycle based on the additional data.

10. The method of claim 8 , wherein the operation data indicative of the duty cycle for the vehicle includes an acceleration characteristic of the vehicle or an aerodynamic speed of the vehicle.

11. The method of claim 8 , further comprising: providing, by the controller, the set of trim parameters to an operator input/output device of the vehicle; and
applying, by the controller, the set of trim parameters with the vehicle in response to receiving an affirmative implementation instruction from the operator input/output device.

12. The method of claim 8 , further comprising: applying, by the controller, one or more boundaries for the received operation data to sample the received operation data at a predefined frequency for a predefined period of time to determine a vehicle duty cycle.

13. The method of claim 12 , further comprising using, by the controller, a hierarchical clustering process to define the one or more boundaries and to sample the received operation data to determine the vehicle duty cycle.

14. The method of claim 8 , wherein the desired operating parameter is at least one of minimizing fuel consumption for the vehicle or incrementally improving fuel economy for the vehicle.

15. A system, comprising:
a controller coupled to an engine, the controller comprising a processor coupled to a non-transitory computer readable medium storing instructions that, when executed by the processor, cause the controller to:
receive operation data indicative of a duty cycle for a vehicle, wherein the duty cycle is a substantially repeatable set of vehicle or vehicle component operations for a particular event or for a predefined time period;
identify a desired vehicle duty cycle from the population of vehicle duty cycles based on the received operation data indicative of the duty cycle for the vehicle and on a desired operating parameter of the vehicle;
receive a set of trim parameters that are electronic operational parameters associated with the desired vehicle duty cycle; and
control one or more operating points of the vehicle based on the set of trim parameters.

16. The system of claim 15 , wherein the operation data indicative of the duty cycle for the vehicle includes an acceleration characteristic of the vehicle or an aerodynamic speed of the vehicle.

17. The system of claim 15 , wherein the instructions, when executed by the processor, further cause the controller to: apply one or more boundaries for the received operation data and sample the received operation data at a constant frequency for a predefined period of time to determine the vehicle duty cycle using a hierarchical clustering process to define the one or more boundaries and to sample the received operation data to determine the vehicle duty cycle.

18. The system of claim 15 , wherein the desired operating parameter is at least one of minimizing fuel consumption for the vehicle or incrementally improving fuel economy for the vehicle.

19. The system of claim 15 , wherein the instructions, when executed by the processor, further cause the controller to: communicate with a remote vehicle tracking and analytics center to receive at least one of the set of trim parameters or the population of vehicle duty cycles.

20. The system of claim 19 , wherein the population of vehicle duty cycles received only pertains to the vehicle duty cycle for the vehicle.
