Driver monitor
Basic functions
During controlled driving, the
driver monitor camera detects
the position and direction the
driver is facing, and whether
their eyes are opened or closed.
Through this, the system deter-
mines if the driver is checking
their surroundings and if the
driver can perform driving oper-
ations.
Warning function
■
In situations such as the follow-
ing, a buzzer will sound and a
message will be displayed to
warn the driver.
When the system determines
that the driver is not paying
attention to the road or their
eyes are closed.
When the driver's face cannot
be detected or the system deter-
mines that the driver has poor
driving posture.
Face identification

The driver monitor is used as a
device to identify faces in order
