Abstract

A vehicle is provided. The vehicle may include a controller that, in response to a number of engine stops that occur within a first predefined time period exceeding a user defined threshold value, inhibit further engine auto stops. The vehicle may include a controller that, in response to a number of engine stops that occur within a first predefined distance travelled by the vehicle exceeding a user defined threshold value, inhibit further engine auto stops.

Claims

1. A vehicle comprising:

an engine;

a human-machine interface (HMI) configured to allow a user to specify a loop threshold value; and

a controller configured to, in response to the vehicle equaling or exceeding the loop threshold value, inhibit further auto stops of the engine wherein the loop threshold value equals a number of auto stops of the engine that occur within a first predefined time period.

2. The vehicle of claim 1, wherein the inhibiting is for a second predefined time period.

3. The vehicle of claim 2, wherein the second predefined time period is user defined.

4. The vehicle of claim 1, wherein the first predefined time period is user defined.

5. The vehicle of claim 1, wherein the loop threshold value equals a number of auto stops of the engine that occur within a predefined distance travelled by the vehicle.

6. The vehicle of claim 5, wherein the controller is further configured to inhibit further auto stops of the engine for a second predefined distance in response to altering a condition within the HMI.

7. The vehicle of claim 6, wherein the second predefined distance is user defined in response to altering a condition within the HMI.

8. The vehicle of claim 7, wherein the first predefined distance is user defined in response to altering a condition within the HMI.

9. The vehicle of claim 1, wherein the HMI is adapted to prompt a user to provide feedback regarding whether further auto stops of the engine should be inhibited, and in response to altering a condition of the HMI, and provide a signal to the controller to inhibit further auto stops of the engine.

10. A vehicle comprising:

an engine;

a controller configured to auto stop the engine in response to a speed of the engine being less than a threshold; and

a human-machine interface (HMI) configured to prompt a user to provide feedback regarding whether further auto stops should be inhibited, and in response to the user altering a condition of the HMI, to provide a signal to the controller to inhibit further auto stops.

11. The vehicle of claim 10, wherein the controller is further configured to, in response to a number of auto stops that occur within a first predefined time period exceeding a user defined threshold value, inhibit further auto stops.

12. The vehicle of claim 11, wherein the inhibiting is for a second predefined time period.

13. The vehicle of claim 11, wherein the controller is further configured to, in response to a number of auto stops that occur within a first predefined distance travelled by the vehicle exceeding a second user predefined threshold value, inhibit further auto stops.

14. The vehicle of claim 13, wherein the inhibiting further auto stops is for a second predefined distance.

15. A vehicle comprising:

an engine;

a controller configured to, in response to a number of auto stops of the engine that occur within a first predefined distance travelled by the vehicle exceeding the loop threshold value, inhibit further auto stops of the engine; and

a human-machine interface (HMI) configured to prompt a user to provide feedback regarding whether further auto stops should be inhibited, and in response to the user altering a condition of the HMI, to provide a signal to the controller to inhibit further auto stops.

16. The vehicle of claim 15, wherein the first predefined distance is user defined.

17. The vehicle of claim 15, wherein the inhibiting is for a second predefined distance.

19. The vehicle of claim 15, wherein the controller is further configured to auto stop the engine in response to a brake pressure exceeding a pressure threshold value.

20. The vehicle of claim 15, wherein the controller is further configured to auto stop the engine in response to a speed of the engine being less than a threshold.
