Toyota announced today
that it has given its Pre-crash Safety System the ability to
determine—as a world's first1—whether a driver's eyes are properly
open. TMC expects this driver-monitoring breakthrough, along with the
system's current ability to determine the direction of the driver's
face, to play an important role in reducing collision-related damage.
The eye-monitoring feature, which is to be offered in vehicle models
scheduled for launch in Japan in the near future, uses a
driver-monitoring camera and image-processing computer to determine the
position of the driver's upper and lower eyelids. If the Pre-crash
Safety System senses that a collision is imminent and also determines
that the driver's eyes are not properly open—or, by using the hitherto
face-monitoring feature, determines that the driver is not facing
forward—it issues a warning to the driver earlier than it would without
such driver-condition information.
TMC believes that the development of driver-condition evaluation
technologies is vital to improving overall vehicle safety performance,
as driver condition is seen as a key factor in traffic safety, with
driver error being the main cause of traffic accidents2.
TMC is, thus, committed to continuing development of such technologies
and to further enhancing its Pre-crash Safety System and other safety
technologies.
As a part of its efforts to realize sustainable mobility, TMC intends
to strengthen its traffic safety initiatives in the future through: 1)
the development of even safer vehicles and technologies based on TMC's
Integrated Safety Management Concept3, 2) participation in the creation
of a safe traffic environment and 3) activities designed to educate
people in traffic safety, thereby contributing to the complete
elimination of traffic casualties, which can be viewed as the ultimate
hope of a society that values mobility.
1. As of December 2007, according to TMC survey.
2. According to a 2005 report by Japan's Institute for Traffic Accident Research and Data Analysis.
3.
TMC's safety technology and vehicle development concept, aimed at
realizing vehicles that do not cause accidents by combining safety
technologies and systems to provide optimal driving support based on
actual driving conditions.
Outline of Pre-crash Safety System Eye-monitoring Feature
Sequence of System Operation
The system issues a
warning to the driver earlier than usual, if it senses that a collision
is imminent and determines that the driver is not facing forward or
that the driver’s eyes are not properly open.
