Problems solved by technology

[0003] The problem with this known technology is that the driver's "microsleep" that induces a large number of traffic accidents often occurs suddenly, and when it occurs, the driver can no longer maintain the Z-shaped route, but directly deviates from the traffic lane

Embodiment Construction

[0030] figure 1 A motor vehicle 1 driving on a road 2 is shown in a schematic plan view. The two carriageways 3 , 4 of the road 2 are each marked by an outer boundary solid line 5 and an intermittent center line 6 . Motor vehicle 1 has two cameras 7 oriented obliquely forward in the direction of travel for detecting a boundary line 5 and a center line 6 adjacent to a roadway 3 of the motor vehicle. It is also conceivable to install a single camera in the middle of the vehicle, so that both the boundary line 5 and the center line 6 are reflected in the single image of this camera.

[0031] The on-board computer 8 of the motor vehicle is programmed to recognize the center line 6 or boundary line 5 of the roadway 3 in the images of the camera 7 according to known methods of pattern recognition. On-board computer 8 calculates the distance of the vehicle from boundary line 5 or center line 6 from the known orientation of camera 7 relative to the longitudinal direction of the road...

Abstract

The invention relates to a method for judging the attention of a driver of a motor vehicle (1) traveling on a traffic lane (3), comprising the following steps: detecting that the motor vehicle (1) is traveling transversely to the direction of travel (S1-S3) in the traffic lane ( 3) the position (d) on; Determining the degree of position (S4) fluctuation; If within a duration of observation, it is detected that in at least one first significant period (t1-t2, t5-t6), the position ( d) The degree of fluctuation (V) is lower than the low first limit value (lim1), and it is detected that the degree of fluctuation (V) exceeds the high value during the second significant period (t4-t5, t7-t8) The second limit value (lim2), then it is judged (S5-S20, S4'-S13') that it is insufficient attention.

Description

technical field [0001] The invention relates to a method and a device for assessing the attentiveness of a driver of a moving motor vehicle. Background technique [0002] Devices and methods for monitoring the driving behavior of a motor vehicle driver, assessing its quality, assessing the level of attention of the driver on the basis of this assessment and, if necessary, generating a warning are known from a large number of published documents. For example, DE 10 2005 012 196 A1 describes a method in which an image of the roadway in front of the vehicle is recorded by means of a camera installed in the vehicle, in which the lane boundary is determined and the distance of the vehicle from the roadway boundary is estimated. In this respect, it is assumed that, as long as the driver does not fall asleep at the steering wheel, zigzag movement of the vehicle can be prevented in most cases and the degree of zigzag movement can be brought close to zero. But if the driver falls as...
