Abstract

One or more embodiments include systems and methods for regulating control of a vehicle infotainment system. In one embodiment, a vehicle computing system includes a user interface which has one or more output components and one or more input components. Software executing in memory of the vehicle computing system may be programmed with rules to reduce driver distraction such as preventing inputs or outputs during vehicle operation. Inputs may be intercepted from the one or more input components of the user interface. Additionally or alternatively, outputs may be intercepted to the output components of the user interface. The intercepted inputs or intercepted outputs may be evaluated for one or more violations based on the rules. If the one or more violations are detected, the inputs or outputs may be prevented during vehicle operation.

First claim

What is claimed is:

1. A system comprising:
a processor configured to:
impose a control interaction count threshold and predefined session duration, responsive to a determination that a driver cognitive load meets a predefined level for limiting user interaction with a predesignated vehicle control; and
disable the vehicle control for the remainder of the session duration, responsive to a count of user interactions with the predesignated vehicle control exceeding the threshold during the session duration.

2. The system of claim 1 , wherein the vehicle control includes a vehicle touch screen interface.

3. The system of claim 1 , wherein the vehicle control includes a vehicle switch.

4. The system of claim 1 , wherein the vehicle control includes a vehicle dial.

5. The system of claim 1 , wherein the vehicle control includes a vehicle button.

6. The system of claim 1 , wherein the session duration persists until a vehicle is powered off.

7. The system of claim 1 , wherein the session duration persists until a predefined period of inactivity with regards to control interaction occurs.

8. The system of claim 1 , wherein the session duration persists until a vehicle including the vehicle control stops moving.

9. The system of claim 1 , wherein the processor is configured to impose the control interaction count threshold and predefined session duration separately for each of a plurality of consecutively executing applications, such that each of the executing applications has an independent count threshold for a control corresponding to the application and an independent session duration.

10. A system comprising:
a processor configured to:
determine that a driver cognitive load meets a predefined level for limiting vehicle control interaction, wherein the vehicle control provides control over an application having at least two aspects that utilize different numbers of control actuations for execution; and
block application aspects requiring more than a threshold number of control actuations, based on a predefined number of control actuations associated with each aspect being higher than the threshold.

11. The system of claim 10 , wherein the vehicle control includes a vehicle touch screen interface.

12. The system of claim 10 , wherein the vehicle control includes a vehicle switch.

13. The system of claim 10 , wherein the vehicle control includes a vehicle dial.

14. The system of claim 10 , wherein the vehicle control includes a vehicle button.

15. The system of claim 10 , wherein the processor is configured to block the application aspects for a predetermined duration.

16. The system of claim 15 , wherein the predetermined duration persists until a vehicle is powered off.

17. The system of claim 15 , wherein the predetermined duration persists until a vehicle including the vehicle control stops moving.

18. The system of claim 10 , wherein the predefined number of control actuations is based on a minimum number of control actuations required to execute a given application aspect.

19. The system of claim 10 , wherein the t predefined number of control actuations is based on stored data indicating a count of user interactions previously observed with regards to execution of a given application aspect.

20. A computer-implemented method comprising:
blocking access to a vehicle application aspect utilizing more than a threshold number of control interactions to execute, determined based on stored, observed user behavior with regards to a number of control interactions previously used to execute the application aspect, the blocking responsive to determining that a user cognitive load exceeds a predefined threshold.
