Abstract

A controller with energy economy rating (EER) calibration logic is configured to adjust a look-ahead time and feed-forward mapping window for vehicle controls according to EER.

Claims

1. A computer-implemented method of operating a vehicle, comprising:

storing vehicle dynamic information (VDI) during vehicle operation;

defining a relationship between VDI over a look-ahead time window;

controlling the vehicle according to the defined relationship;

wherein when a target energy economy rating (EER) is less than a predetermined value, controlling the vehicle over a larger look-ahead time window than when the target EER is less than the predetermined value.

2. The method of claim 1, further comprising:

receiving the target EER.

3. The method of claim 1, further comprising:

correlating EER with a driving style;

wherein an EER greater than or equal to zero is correlated with an aggressive driving style;

wherein an EER less than zero is correlated with a smooth driving style.

4. A controller with energy economy rating (EER) calibration logic configured to adjust a look-ahead feed-forward mapping window for vehicle controls according to EER.

5. The controller of claim 4, further comprising:

EER calculation logic, configured to calculate a desired energy economy rating.

6. The controller of claim 4, wherein the EER calibration logic is configured to output driver pedal commands to achieve an EER that corresponds to a desired driving style.

7. A system for controlling a vehicle, comprising:

vehicle dynamic sensors collecting vehicle dynamic information (VDI);

memory storing the plurality of VDI;

a controller which controls a first vehicle subsystem associated with a first VDI based on relationship data between the first VDI and a second VDI over a flexible time-mapping window;

an energy economy rating calibrator, altering the time-mapping window in which control over the first vehicle subsystem is based.

8. The system of claim 7, wherein the first vehicle subsystem is a driver vehicle interface.

9. The system of claim 8, wherein the energy economy rating (EER) calibrator is configured to correlate EER with a predetermined driving style;

wherein a target EER greater than or equal to zero is correlated with an aggressive driving style; and

wherein a target EER less than zero is correlated with a smooth driving style.

10. The system of claim 7, wherein the energy economy rating (EER) calibrator is configured to reduce the time window where the target EER is greater than or equal to zero.

11. The system of claim 7, wherein the energy economy rating (EER) calibrator is configured to correlate EER with a predetermined driving style;

wherein a target EER greater than or equal to zero is correlated with an aggressive driving style; and

wherein a target EER less than zero is correlated with a smooth driving style.

12. The system of claim 7, further comprising:

a user interface for receiving a target energy economy rating (EER).
