Abstract

A vision system of a vehicle includes an interior camera disposed in an interior cabin of a vehicle and having a field of view interior of the vehicle that encompasses an area typically occupied by a head of a driver of the vehicle. An image processor is operable to process image data captured by the camera. The image processor is operable to determine the presence of a person'"'"'s head in the field of view of the camera and to compare features of the person'"'"'s face to features of an authorized driver. Responsive at least in part to the comparison of features, operation of the vehicle is allowed only to an authorized driver. The system may store features of one or more authorized driver and may allow operation of the vehicle only when the person occupying the driver seat is recognized or identified as an authorized driver.

Claims

1. A vision system of a vehicle, said vision system comprising:

an interior camera disposed in an interior cabin of a vehicle and having a field of view interior of the vehicle that encompasses an area typically occupied by a head of a driver of the vehicle;

an image processor operable to process image data captured by said interior camera;

wherein said image processor is operable to determine the presence of a person'"'"'s head in the field of view of said interior camera and to compare features of the person'"'"'s face to features of an authorized driver; and

wherein, responsive at least in part to the comparison of features, operation of the vehicle is allowed only to an authorized driver.

2. The vision system of claim 1, comprising an exterior camera having a field of view exterior of the vehicle, wherein said image processor is operable to determine the presence of a person in the field of view of said exterior camera and to compare features of the person in the field of view of said exterior camera to features of an authorized driver, wherein, responsive at least in part to the comparison of features of the person in the field of view of said exterior camera, opening of a door of the vehicle is allowed only to an authorized driver.

3. The vision system of claim 1, wherein, responsive to a comparison of a weight of an authorized driver to a weight of the person when the person is occupying the driver seat of the vehicle as determined by a seat sensor at the driver seat, operation of the vehicle is allowed only to an authorized driver.

4. The vision system of claim 1, wherein, responsive to a comparison of a location of the person'"'"'s head when the person is occupying the driver seat of the vehicle to a location of the head of an authorized driver, operation of the vehicle is allowed only to an authorized driver.

5. The vision system of claim 1, wherein said vision system is operable to learn features of an authorized driver.

6. The vision system of claim 1, wherein said vision system is operable to store features of multiple authorized drivers and, responsive to comparison of a person'"'"'s face to features of the authorized drivers, operation of the vehicle is allowed only to one of the authorized drivers.

7. The vision system of claim 1, wherein said vision system is operable to determine a gaze direction of the authorized driver while the authorized driver is operating the vehicle.

8. The vision system of claim 7, wherein said vision system is operable to adjust at least one accessory responsive to the gaze direction of the authorized driver.

9. The vision system of claim 1, wherein said vision system learns a driving characteristic of the authorized driver and adjusts at least one accessory of the vehicle responsive to the learned driving characteristic.

10. The vision system of claim 9, wherein said vision system comprises a display screen operable to display traffic sign information indicative of a traffic sign ahead of the vehicle to enhance the authorized driver'"'"'s awareness of the traffic sign.

11. The vision system of claim 10, wherein said vision system is operable to determine a gaze direction of the authorized driver while the authorized driver is operating the vehicle and is operable to determine when the authorized driver views the traffic sign, and wherein said vision system adjusts the display of the traffic sign responsive to the driver'"'"'s gaze direction being towards the traffic sign.

12. The vision system of claim 11, wherein said vision system learns an attentiveness of the authorized driver when the authorized driver is operating the vehicle and wherein said vision system adjusts the display of the traffic sign responsive to the authorized driver'"'"'s attentiveness and the driver'"'"'s gaze being towards the traffic sign.

13. A vision system of a vehicle, said vision system comprising:

an interior camera disposed in an interior cabin of a vehicle and having a field of view interior of the vehicle that encompasses an area typically occupied by a head of a driver of the vehicle;

wherein said vision system is operable to store features of multiple authorized drivers;

an image processor operable to process image data captured by said interior camera;

wherein said image processor is operable to determine the presence of a person'"'"'s head in the field of view of said interior camera and to compare features of the person'"'"'s face to features of the authorized drivers;

wherein, responsive at least in part to the comparison of features, operation of the vehicle is allowed only to one of the authorized drivers; and

wherein said vision system is operable to determine a gaze direction of the authorized driver while the authorized driver is operating the vehicle.

14. The vision system of claim 13, comprising an exterior camera having a field of view exterior of the vehicle, wherein said image processor is operable to determine the presence of a person in the field of view of said exterior camera and to compare features of the person in the field of view of said exterior camera to features of an authorized driver, wherein, responsive at least in part to the comparison of features of the person in the field of view of said exterior camera, opening of a door of the vehicle is allowed only to an authorized driver.

15. The vision system of claim 13, wherein, responsive to a comparison of a location of the person'"'"'s head when the person is occupying the driver seat of the vehicle to a location of the head of an authorized driver, operation of the vehicle is allowed only to an authorized driver.

16. The vision system of claim 13, wherein said vision system is operable to learn features of an authorized driver.

17. The vision system of claim 13, wherein said vision system is operable to adjust at least one accessory responsive to the gaze direction of the authorized driver.

18. The vision system of claim 13, wherein said vision system learns a driving characteristic of the authorized driver and adjusts at least one accessory of the vehicle responsive to the learned driving characteristic.

19. A vision system of a vehicle, said vision system comprising:

an interior camera disposed in an interior cabin of a vehicle and having a field of view interior of the vehicle that encompasses an area typically occupied by a head of a driver of the vehicle;

wherein said vision system is operable to store features of multiple authorized drivers;

an image processor operable to process image data captured by said interior camera;

wherein said image processor is operable to determine the presence of a person'"'"'s head in the field of view of said interior camera and to compare features of the person'"'"'s face to features of authorized drivers;

wherein, responsive at least in part to the comparison of features, operation of the vehicle is allowed only to one of the authorized drivers; and

wherein said vision system learns a driving characteristic of the authorized drivers and adjusts at least one accessory of the vehicle responsive to the learned driving characteristic of the authorized driver that is operating the vehicle.

20. The vision system of claim 19, wherein said vision system comprises a display operable to display traffic sign information indicative of a traffic sign ahead of the vehicle to enhance the authorized driver'"'"'s awareness of the traffic sign, and wherein said vision system is operable to determine a gaze direction of the authorized driver while the authorized driver is operating the vehicle and is operable to determine when the authorized driver views the traffic sign, and wherein said vision system learns an attentiveness of the authorized driver when the authorized driver is operating the vehicle, and wherein said vision system adjusts the display of the traffic sign responsive to the authorized driver'"'"'s attentiveness and the determined driver'"'"'s gaze being towards the traffic sign.
