Method for assessing driver attentiveness
First Claim
Patent Images
1. A method for assessing an attentiveness of a driver of a motor vehicle traveling in a lane comprising:
- detecting a position of the motor vehicle in the lane transverse to a direction of travel;
determining an extent of fluctuations of the position; and
assessing the attentiveness as insufficient if within an observation period a first significant period in which the extent of fluctuations of the position falls below a first low limiting value and a second significant period is detected in which the extent of fluctuations exceeds a second high limiting value, andwherein the first significant period is assessed as significant if a first duration of the first significant period exceeds a first significance limiting value; and
wherein the second period is assessed as significant if a second duration of the second period exceeds a second significance limiting value.

Abstract
A method is provided for assessing the attentiveness of the driver of motor vehicle traveling in a lane including, but not limited to detecting the position of the motor vehicle on the lane transverse to the direction of travel, determining the extent of fluctuations of the position, and assessing the attentiveness as insufficient if within an observation period at least one first significant period is detected in which the extent of fluctuations of the position falls below a first low limiting value and a second significant period is detected in which the extent of the fluctuations exceeds a second high limiting value.

10. A non-transitory computer readable medium embodying a computer program product, said computer program product comprising:
-
an assessment program for assessing an attentiveness of a driver of a motor vehicle traveling in a lane, the assessment program configured to; detect a position of the motor vehicle in the lane transverse to a direction of travel; determine an extent of fluctuations of the position relative to the lane transverse to the direction of travel; and assess the attentiveness as insufficient if within an observation period a first significant period in which the extent of fluctuations of the position falls below a first low limiting value and a second significant period is detected in which the extent of fluctuations exceeds a second high limiting value; wherein the first significant period is assessed as significant if a first duration of the first significant period exceeds a first significance limiting value; and wherein the second period is assessed as significant if a second duration of the second period exceeds a second significance limiting value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
