Abstract

Vehicles equipped with an automatic start-stop system may include an interface for conveying inhibitors preventing an engine from auto-stopping in addition to the status of the automatic start-stop system. The system may identify one or more inhibitors actively preventing an auto-stop event from occurring and select at least one of the active inhibitors based on a priority scheme. The interface may communicate the at least one selected inhibitor to a driver using a display or a speaker, or both.

Claims

1. A system comprising:

a controller configured to receive input indicative of vehicle propulsion conditions and a presence of one or more auto-stop inhibitors; and

an interface, in communication with the controller, configured to output a message identifying at least one of the inhibitors based on a priority scheme when vehicle propulsion conditions for an auto-stop event are satisfied.

2. The system of claim 1, wherein the priority scheme is at least partially based on whether a driver has at least partial control over an inhibitor of the one or more auto-stop inhibitors.

3. The system of claim 1, wherein the interface includes a display having a selectable automatic start-stop display screen that displays the message identifying the at least one inhibitor.

4. The system of claim 3, wherein the display further includes an automatic start-stop indicator that is displayed in one of a plurality of indicator states based on a status of an automatic start-stop system.

5. The system of claim 3, wherein the controller is further configured to receive input indicating a restart action is required to restart an engine and the display is configured to display a pop-up alert conveying the required restart action, wherein the pop-up alert is displayed on any one of a number of selectable information display screens.

6. The system of claim 3, wherein the controller latches a current highest priority inhibitor according to the priority scheme and the display displays the message identifying the latched inhibitor.

7. The system of claim 6, wherein the latched inhibitor remains latched for as long as it is active despite a higher priority inhibitor subsequently becoming active.

8. A method comprising:

receiving input indicating vehicle propulsion conditions for auto-stopping an engine are satisfied and one or more auto-stop inhibitors are present; and

outputting a message corresponding to at least one of the inhibitors based on an priority scheme.

9. The method of claim 8, wherein the step of outputting a message corresponding to at least one of the inhibitors includes displaying the message on a display based on a predetermined display priority scheme.

10. The method of claim 9, wherein the display priority scheme is at least partially based on whether a driver has at least partial control over an inhibitor.

11. The method of claim 9, wherein the message is displayed on a selectable automatic start-stop display screen.

12. The method of claim 9, wherein displaying the message on a display includes:

latching a current highest priority inhibitor according to the display priority scheme; and

displaying the message identifying the latched inhibitor on the display.

13. The method of claim 12, wherein the latched inhibitor remains latched for as long as it is active despite a higher priority inhibitor subsequently becoming active.

14. A method comprising:

receiving input indicating an engine is currently auto-stopped and an engine restart is being requested;

identifying a restart action to restart the engine; and

outputting a message corresponding to the restart action.

15. The method of claim 14, wherein outputting a message corresponding to the restart action includes displaying the message on a display.

16. The method of claim 15, wherein the message is a pop-up alert that is displayed on one of a number of selectable information display screens.

17. The method of claim 14, wherein the message corresponding to the restart action includes instructions to restart the engine manually.

18. The method of claim 14, wherein the engine restart request is in response to a request for vehicle propulsion.

19. The method of claim 18, wherein the message corresponding to the restart action includes instructions to operate a pedal before the engine is automatically restarted.

20. The method of claim 18, wherein the message corresponding to the restart action includes instructions to select a particular gear before the engine is automatically restarted.
