Abstract

A system includes a processor configured to receive a vehicle location and to access driver-specific driving-mode-change data for the vehicle location. The processor is also configured to determine, based on the accessed data, if a vehicle driving-mode-change has previously occurred at the vehicle location and context a sufficient number of times to cross a predefined threshold and, if so, to automatically change a vehicle driving-mode to the driving-mode associated with the previous driving-mode-change.

Claims

1. A system comprising:

a processor configured to;

access driver-specific driving-mode-change data for a current vehicle location;

determine, based on the accessed data, if a vehicle driving-mode-change at the vehicle location previously occurred sufficiently to cross a predefined threshold ratio of occurrences to number of instances the vehicle was at the vehicle location; and

if the vehicle driving-mode-change occurred more than the threshold ratio, automatically change a vehicle driving-mode to a driving-mode associated with the driving-mode-change.

2. The system of claim 1, wherein the processor is further configured to receive a vehicle context, and wherein the processor is configured to determine if the vehicle-driving-mode change sufficiently occurred previously at the vehicle location, while an aspect of the received context was also present, to cross the predefined threshold ratio, the ratio being occurrences while the context aspect was present to instances the vehicle was at the vehicle location while the context aspect was present.

3. The system of claim 2, wherein the at least one aspect of the received context includes current weather conditions.

4. The system of claim 2, wherein the at least one aspect of the received context includes current occupant make-up.

7. The system of claim 1, wherein the processor is further configured to receive a vehicle context, and wherein the processor is further configured to block a driving-mode change that would otherwise be automatically engaged as a result of the driving-mode-change that previously occurred sufficiently to cross the threshold, the block being based on at least one aspect of the received context.

8. The system of claim 7, wherein the at least one aspect includes a weather condition.

5-6. -6. (canceled)

9. A computer-implemented method comprising:

accessing driver-specific driving-mode-change data for a current vehicle location;

determining, based on the accessed data, if a vehicle driving-mode-change at the vehicle location has previously occurred sufficiently to cross a predefined threshold threshold ratio of occurrences to number of instances the vehicle was at the vehicle location; and

if the vehicle driving-mode-change occurred more than the threshold ratio, automatically changing a vehicle driving-mode to a driving-mode resulting from the driving-mode-change.

10. The method of claim 9, further including receiving a vehicle context, and wherein the determining includes determining if the vehicle-driving-mode change sufficiently occurred previously at the vehicle location, under at least one aspect of the received context, to cross the predefined threshold.

11. The method of claim 10, wherein the at least one aspect of the received context includes current weather conditions.

12. The method of claim 10, wherein the at least one aspect of the received context includes current occupant make-up.

15. The method of claim 9, further including receiving a vehicle context, and blocking a driving-mode change that would otherwise be automatically engaged as a result of the driving-mode-change that previously occurred sufficiently to cross the threshold, the blocking being based on at least one aspect of the received context.

16. The method of claim 15, wherein the at least one aspect includes a weather condition.

13-14. -14. (canceled)

17. A system comprising:

a manual driving-mode control for manual input of a vehicle-driving-mode change;

a processor, in communication with the manual control, configured to;

receive driver input indicating a vehicle-driving-mode change;

receive a vehicle location; and

store an instance of correspondence between the vehicle-driving-mode change and the vehicle location, including update of a likelihood-of-occurrence variable value, representing a present and past receipt of the driver-input indicating a vehicle-driving-mode change at the received vehicle location.

18. The system of claim 17, wherein the processor is further configured to receive vehicle context and to store at least one aspect of the vehicle context with respect to the instance of correspondence, such that the instance of correspondence is between the at least one aspect of the vehicle context, the vehicle-driving-mode-change and the vehicle location.

19. (canceled)

20. The system of claim 19, wherein the processor is further configured to decay the variable value, indicating an instance of no vehicle-driving-mode change and vehicle location correspondence, when the processor receives a vehicle location, for which a likelihood-of-occurrence variable value was previously updated, without receiving driver input indicating a vehicle-driving-mode change.
