Abstract

A user discrimination control system controls functionality made available by a vehicle infotainment device by reducing functionality provided to the driver while allowing enhanced functionality to another passenger in the vehicle. The system includes a human machine interface located in a vehicle for allowing an occupant to interface with the infotainment device. A passenger detection sensor senses a condition indicative of a passenger other than the driver interfacing with the human machine interface. A video imaging system detects a driver distraction condition. A controller controls functions made available by the infotainment device by allowing one of first and second levels of functionality based on the sensed conditions.

Claims

1. A user discrimination control system for use in controlling an electronic device in a vehicle adapted to transport a driver and one or more passengers, said system comprising:

a human machine interface located in a passenger compartment of the vehicle for allowing an occupant in the vehicle to interface with the electronic device;

a passenger detection sensor for sensing a condition indicative of a passenger other than the driver interfacing with the human machine interface; and

a controller for controlling the functions made available by the electronic device, wherein the controller provides one of first and second levels of functionality based on the sensed condition.

2. The user discrimination control system as defined in claim 1 further comprising a driver distraction sensor for sensing a condition indicative of distraction of the driver, wherein the controller reduces functionality of the electronic device when driver distraction is detected.

3. The user discrimination control system as defined in claim 2, wherein the driver distraction sensor comprises an imaging camera for monitoring a facial characteristic of the driver.

4. The user discrimination control system as defined in claim 3, wherein the facial characteristic comprises eye gaze of the driver.

5. The user discrimination control system as defined in claim 1, wherein the passenger sensor comprises a proximity sensor for detecting movement of the passenger in close proximity to the human machine interface.

6. The user discrimination control system as defined in claim 1, wherein the electronic device comprises an infotainment device.

7. The user discrimination control system as defined in claim 1 further comprising a sensor for determining the presence of a passenger in the vehicle, wherein the controller provides reduced functionality when a passenger is not detected.

8. The user discrimination control system as defined in claim 7, wherein the system determines if the passenger is one of an adult and a child, wherein the controller reduces functionality of the system when the passenger is a child.

9. A user discrimination control system for use in controlling an electronic device in a vehicle adapted to transport an occupant, said system comprising:

a driver distraction sensor for detecting a condition indicative of distraction of a driver of the vehicle; and

a controller for controlling functions made available by the electronic device, wherein the controller provides one of first and second levels of functionality of the electronic device based on the sensed driver distraction condition.

10. The user discrimination control system as defined in claim 9, wherein the controller provides reduced functionality of the electronic device when the driver distraction sensor senses distraction of the driver of the vehicle.

11. The user discrimination control system as defined in claim 10, wherein the driver distraction sensor comprises an imaging camera for tracking a facial characteristic of the driver.

12. The user discrimination control system as defined in claim 11, wherein the facial characteristic comprises eye gaze of the driver.

13. The user discrimination control system as defined in claim 9, wherein the electronic device comprises an infotainment device.

14. The user discrimination control system as defined in claim 9 further comprising a human machine interface located in a passenger compartment of a vehicle for allowing an occupant of the vehicle to interface with an electronic device.

15. The user discrimination control system as defined in claim 14 further comprising a passenger detection sensor for sensing a condition indicative of a passenger other than the driver interfacing with the human machine interface, wherein the controller provides the one of first and second levels of functionality based further on the passenger detected condition.

16. The user discrimination control system as defined in claim 15, wherein the passenger sensor comprises a proximity sensor for detecting movement of the passenger in close proximity to the human machine interface.

17. The user discrimination control system as defined in claim 9 further comprising a sensor for detecting the presence of a passenger in the vehicle, wherein the controller provides reduced functionality when a passenger is not detected.

18. The user discrimination control system as defined in claim 17, wherein the system determines if the passenger is one of an adult and a child, wherein the controller reduces functionality of the system when the passenger is a child.

19. A method of controlling an electronic device in a vehicle adapted to transport a driver and one or more passengers, said method comprising the steps of:

providing a human machine interface located in a passenger compartment of the vehicle for allowing an occupant in the vehicle to interface with an electronic device;

sensing a passenger interface condition indicative of a passenger other than the driver interfacing with the human machine interface; and

controlling functions made available by the electronic device by allowing one of first and second levels of functionality based on the sensed passenger interface condition.

20. The method as defined in claim 19 further comprising the step of sensing a driver distraction condition indicative of distraction of the driver and reducing functionality of the electronic device when driver distraction condition is detected.

21. The method as defined in claim 20, wherein the step of sensing a driver distraction condition comprises monitoring a facial characteristic of the driver with an imaging camera.

22. The method as defined in claim 21, wherein the step of monitoring a facial characteristic comprises monitoring eye gaze of the driver.

23. The method as defined in claim 21, wherein the step of sensing a passenger interface condition comprises detecting movement of the passenger in close proximity to the human machine interface, and wherein reduced functionality of the electronic device is allowed when movement is not detected.

24. A method of controlling an electronic device in a vehicle adaptive to transport an occupant, said method comprising the steps of:

sensing a driver distraction condition indicative of distraction of a driver of the vehicle; and

controlling functions made available by the electronic device by allowing one of first and second levels of functionality of the electronic device based on the sensed driver distraction condition.

25. The method as defined in claim 24, wherein the step of controlling functions comprises reducing functionality of the electronic device when the driver distraction condition is sensed.

26. The method as defined in claim 24, wherein the step of sensing a driver distraction condition comprises tracking a facial characteristic of the driver.

27. The method as defined in claim 26, wherein the step of tracking the facial characteristics of the driver comprises tracking eye gaze of the driver.

28. The method as defined in claim 24 further comprising the steps of:

providing a human machine interface located in the passenger compartment of the vehicle for allowing an occupant in the vehicle to interface with the electronic device; and

sensing a condition indicative of a passenger other than the driver interfacing with the human machine interface, wherein one of the first and second levels of functionality is allowed based further on the sensed passenger interfacing condition.

29. The method as defined in claim 28, wherein the step of sensing a passenger interfacing condition comprises of detecting movement of the passenger in close proximity to the human machine interface.
