Method and device for avoiding a tunnel vision
A method for avoiding a tunnel vision of a motor vehicle driver includes detecting an instantaneous viewing direction of the driver; comparing the instantaneous viewing direction with at least one previous viewing direction; detecting a tunnel vision if a rate of change between the viewing directions and/or if an angular range of the viewing direction is not reached; and stimulating the motor vehicle driver to avoid the tunnel vision. A device for avoiding a tunnel vision of the driver includes a camera for detecting an instantaneous viewing direction of the motor vehicle driver; a control unit for comparing the instantaneous viewing direction with at least one previous viewing direction and for detecting a tunnel vision if a rate of change between the viewing directions and/or if an angular range of the viewing direction is not reached, and a device for stimulating the motor vehicle driver to avoid the tunnel vision.
1. A method for avoiding a tunnel vision of a motor vehicle driver driving a motor vehicle, the method comprising:
detecting a plurality of viewing directions of the motor vehicle driver, each viewing direction corresponding to a different moment in time, and the plurality of viewing directions corresponding to a predefined period of time;
storing the plurality of viewing directions;
detecting, via a control unit, an instantaneous viewing direction of the motor vehicle driver, wherein a time of the instantaneous viewing direction is preceded by the predefined period of time;
comparing, via the control unit, the instantaneous viewing direction with more than one of the stored viewing directions of the period of time to determine a rate of change between the instantaneous viewing direction and at least one of the stored viewing directions;
determining a risk of collision with an obstacle that is within a field of view of the motor vehicle driver;
detecting, via the control unit, a tunnel vision if the risk of collision is above a predetermined criterion and the rate of change is below a limiting value; and
in response to detecting the tunnel vision, stimulating the motor vehicle driver to avoid the tunnel vision.
2. The method of claim 1 , wherein the motor vehicle driver is stimulated if, in addition, a predictive safety system of the motor vehicle detects a danger in an instantaneous path of travel of the motor vehicle.
3. The method of claim 2 , wherein the stimulation includes a notification concerning a collision-free path of travel for the motor vehicle.
4. The method of claim 1 wherein the stimulation is a visual stimulation.
5. The method of claim 1 , wherein a view vector is generated from the viewing direction and the view vector is analyzed.
6. A device for avoiding a tunnel vision of a motor vehicle driver, comprising:
a camera that:
detects a plurality of viewing directions of the motor vehicle driver, each viewing direction corresponding to a different moment in time, and the plurality of viewing directions corresponding to a predefined period of time, and
detects an instantaneous viewing direction of the motor vehicle driver, wherein a time of the instantaneous viewing direction is preceded by the predefined period of time;
a control unit to determine a risk of collision with an obstacle that is within a field of view of the motor vehicle driver, and to perform a comparison of the instantaneous viewing direction with inure than one of the stored viewing directions of the period of time to determine a rate of change between the instantaneous viewing direction and at least one of the stored viewing directions, wherein:
the control unit detects a tunnel vision if the risk of collision is above a predetermined criterion and the rate of change is below a limiting value; and
a stimulating device to stimulate, in response to the control unit detecting the tunnel vision, the motor vehicle driver to avoid the tunnel vision.
7. The device of claim 6 , wherein the device for stimulating includes a visual display.
8. The device of claim 7 , wherein the visual display is situated in the area of the windshield of the motor vehicle.
9. The device of claim 7 , wherein the visual display has at least one LED and/or a laser for displaying information.
10. The method of claim 1 , wherein the limiting value is 0.1°/ms.
11. The method of claim 1 , wherein the limiting value is 0.05°/ms.
12. The device of claim 6 , wherein the limiting value is 0.1°/ms.
13. The device of claim 6 , wherein the limiting value is 0.05°/ms.
14. The method of claim 1 , wherein an imminent tunnel vision is detected if the rate of change decreases.
15. The device of claim 6 , wherein the control unit is adapted to detect an imminent tunnel vision if the rate of change decreases.
