Driver Attention Camera
Principle
A camera in the instrument cluster monitors
the driver's activity and, depending on the
equipment, the driver's viewing direction.
General information
For support by assistance systems, the atten-
tion of the driver is analyzed by evaluating the
head position and eye opening of the driver.
For full operability, make sure that the field of
view of the Driver Attention Camera is not ob-
structed.
