Abstract

A vehicle computer system (e.g., on-board vehicle computer system) obtains a fuel economy performance goal for a vehicle (e.g., an engine speed goal or a vehicle speed goal) that is based on a configuration of the vehicle; calculates a count of events in which a current value exceeds the goal; compares the count of events with a threshold count; and generates one or more notifications based at least in part on the comparison (e.g., for display on an operator interface). The vehicle computer system also calculates an engine speed and a vehicle speed score for a driver of the vehicle based at least in part on comparisons of current speeds with the speed goals. Scoring and other data may be displayed or stored for further processing.

Claims

1. A vehicle computer system comprising:

at least one processing unit; and

a memory having stored therein computer-executable instructions configured to cause the vehicle computer system to;

obtain a fuel economy performance goal for a vehicle, wherein the fuel economy performance goal is based at least in part on a configuration of the vehicle, and wherein the fuel economy performance goal is an engine speed goal or a vehicle speed goal;

calculate a count of events in which a current value exceeds the fuel economy performance goal, wherein the current value is a current engine speed or a current vehicle speed;

perform a comparison of the count of events with a threshold count; and

generate one or more notifications based at least in part on the comparison.

2. The vehicle computer system of claim 1, wherein the fuel economy performance goal is an engine speed goal.

3. The vehicle computer system of claim 2, wherein the computer-executable instructions are further configured to cause the vehicle computer system to calculate an engine speed score for a driver of the vehicle.

4. The vehicle computer system of claim 2, wherein the engine speed goal is based at least in part on a peak torque engine speed for the vehicle.

5. The vehicle computer system of claim 1, wherein the fuel economy performance goal is a vehicle speed goal.

6. The vehicle computer system of claim 5, wherein the computer-executable instructions are further configured to cause the vehicle computer system to calculate a vehicle speed score for a driver of the vehicle.

7. The vehicle computer system of claim 1 further comprising an operator interface, wherein the one or more notifications are displayed by the operator interface.

8. The vehicle computer system of claim 1, wherein the vehicle computer system is an on-board vehicle computer system.

9. A computer-implemented method comprising:

obtaining a fuel economy performance goal for a vehicle, wherein the fuel economy performance goal is based at least in part on a configuration of the vehicle, and wherein the fuel economy performance goal is an engine speed goal or a vehicle speed goal;

calculating a count of events in which a current value exceeds the fuel economy performance goal, wherein the current value is a current engine speed or a current vehicle speed;

performing a comparison of the count of events with a threshold count; and

generating one or more notifications based at least in part on the comparison.

10. The method of claim 9, wherein the fuel economy performance goal is an engine speed goal.

11. The method of claim 10, further comprising calculating an engine speed score for a driver of the vehicle.

12. The method of claim 10, wherein the engine speed goal is based at least in part on a peak torque engine speed for the vehicle.

13. The method of claim 9, wherein the fuel economy performance goal is a vehicle speed goal.

14. The method of claim 13, further comprising calculating a vehicle speed score for a driver of the vehicle.

15. The method of claim 9, wherein the method is performed by an on-board vehicle computer system.

16. A vehicle computer system comprising:

at least one processing unit; and

a memory having stored therein computer-executable instructions configured to cause the vehicle computer system to;

obtain fuel-economy performance goals for a vehicle, wherein at least one of the fuel economy performance goals is based at least in part on a configuration of the vehicle, and wherein the fuel economy performance goals comprise an engine speed goal and a vehicle speed goal;

perform a comparison of a current engine speed with the engine speed goal;

calculate an engine speed score for a driver of the vehicle based at least in part on the comparison of the current engine speed with the engine speed goal;

perform a comparison of a current vehicle speed with the vehicle speed goal;

calculate a vehicle speed score for the driver of the vehicle based at least in part on the comparison of the current vehicle speed with the vehicle speed goal; and

output the engine speed score and the vehicle speed score.

17. The vehicle computer system of claim 16, wherein the computer-executable instructions are further configured to cause the vehicle computer system to calculate a combined score for a driver of the vehicle based at least in part on the engine speed score and the vehicle speed score.

18. The vehicle computer system of claim 17, wherein the combined score is further based on cruise control usage.

19. The vehicle computer system of claim 16, wherein the computer-executable instructions are further configured to cause the vehicle computer system to generate a representation of the combined score for display on an operator interface.

20. The vehicle computer system of claim 16, wherein the computer-executable instructions are further configured to cause the vehicle computer system to generate representations of the engine speed score and the vehicle speed score for display on an operator interface.

21. The vehicle computer system of claim 16, wherein the vehicle computer system is an on-board vehicle computer system.
