Abstract

Various examples of a driver monitoring apparatus and a method of disabling a driver facing camera are disclosed. A driver monitoring controller receives video images of a driver and transmits control messages to a driver facing camera. The driver monitoring controller receives a signal indicating that the driver desires to disable the driver facing camera. The driver monitoring controller receives messages indicating a vehicle state. The control logic of the driver monitoring controller disables the driver facing camera by transmitting a control message to disable the driver facing camera in response to a control input indicating the driver desires to disable the driver facing camera and a vehicle state message indicating a vehicle state does not meet a predetermined condition. The control logic of the driver monitoring controller enables the camera automatically in response to a vehicle state message indicating the vehicle state meets the predetermined condition.

Claims

1. A driver monitoring controller for a vehicle comprising:

a camera communications port for receiving video images of a driver and transmitting control messages to an associated driver facing camera;

a control input for receiving a signal indicating that the driver desires to disable only the associated driver facing camera;

a vehicle communications port for receiving and transmitting messages; and

control logic in communication with the camera communications port, the control input and the vehicle communications port, wherein the control logic disables only the driver facing camera by transmitting a control message to disable the driver facing camera at the camera communications port in response to receiving the signal at the control input indicating the driver desires to disable only the driver facing camera and receiving a vehicle state message at the vehicle communications port indicating a vehicle state does not meet a predetermined condition.

2. The driver monitoring controller as in claim 1, wherein the control logic enables the associated driver facing camera in response to receiving a vehicle state message indicating the vehicle state meets the predetermined condition.

3. The driver monitoring controller as in claim 1, wherein the vehicle communications port receives the vehicle state message from an associated safety system controller.

4. The driver monitoring controller as in claim 1, wherein the associated driver facing camera is integrated with the driver monitoring controller.

5. The driver monitoring controller as in claim 1, wherein the predetermined condition is at least one of a vehicle speed exceeding a minimum speed, a detection of a forward object, and the vehicle being outside a lane of travel.

6. The driver monitoring controller as in claim 1, wherein the control logic transmits messages indicating a state of the associated driver facing camera to the vehicle communications port.

7. The driver monitoring controller as in claim 1, wherein the control logic transmits a control message to enable the associated driver facing camera within 100 milliseconds of receiving the vehicle state message indicating the vehicle state meets the predetermined condition.

8. The driver monitoring apparatus as in claim 1, wherein the control logic is further capable of recording the operating state of the camera.

9. A method of monitoring a driver of a vehicle comprising:

enabling a camera for receiving images of a driver;

receiving a control input indicating the driver desires to disable only the camera;

receiving a message indicating a vehicle state does not meet a predetermined condition;

disabling only the camera in response to receiving the control input and the message indicating the vehicle state does not meet the predetermined condition;

receiving a message indicating a vehicle state meets the predetermined condition;

re-enabling the camera automatically in response to receiving the message indicating the vehicle state meets the predetermined condition.

10. The method as in claim 9, wherein re-enabling the camera occurs in response to the predetermined condition being at least one of a speed exceeding a minimum speed, a detection of a forward object, and the vehicle out of a lane of travel.

11. The method as in claim 9, further comprising indicating the operating state of the camera.

12. The method as in claim 9, further comprising re-enabling the camera within one hundred milliseconds from receiving the message indicating the vehicle state meets the predetermined condition.

13. A system for monitoring a driver comprising:

a camera for capturing images of a driver of a vehicle;

a manual switch associated with the camera for disabling only the camera; and

a driver monitoring controller in communication with the camera;

wherein only the camera is disabled in response to the switch activation and remains disabled until enabled automatically by the driver monitoring controller in response to receiving a signal indicating a vehicle state meets a predetermined condition.

14. The system as in claim 13, further comprising a vehicle safety system for transmitting the signal indicating the vehicle state meets the predetermined condition.

15. The system as in claim 14, wherein the driver monitoring controller and the vehicle safety system are integrated.

16. The system as in claim 13, wherein the camera and the driver monitoring controller are integrated.

17. The system as in claim 13, further comprising a display for receiving a signal indicating the operating state of the camera.

18. The system as in claim 13, wherein the driver monitoring controller records the operating state of the camera.

19. The system as in claim 13, wherein the manual switch is integrated with the camera.

20. The system as in claim 13, wherein the predetermined condition is at least one of the vehicle speed exceeding a minimum speed, a detection of a forward object, and the vehicle out of the lane of travel.
