Technology
According to the
National Policy Agency, the number of the dead in a car accident halved for the
past 10 years, but the ratio of pedestrians to the total dead is on the rise.
Automakers are actively addressing the development of a technology to prevent a
car accident from occurring.
Nagoya University Professor Goro Ohinata paved the way to the technology to judge the
deterioration of attentiveness of the driver from his eye movement in alliance
with Toyota Motor. He focused on the fact that eye movement becomes slower when
the driver gets tired or enters a crossing in an unstable emotional status. He
is trying to build a mechanism to check the eye movement of the driver with the
help of a camera installed in a car and give him a warning when his eye
movement becomes slower. Using a driving simulator, he tested the mechanism
against people of various generations. The three charge-coupled device (CCD)
cameras installed in the car successfully detected the abnormal change of the
driver. He plans to test the mechanism using a real car this autumn.
Nissan built EPORO
that is a car-like robot. It runs with other robots keeping a certain distance
between them while avoiding obstacles using a sensor. The company got ideas
from a school of fish that travels to the destination, though each of fish
seems to move at is own discretion. Honda developed a system to tell the driver
the timing to apply the brake. The company tested this technology in Italy, and
plans to put it into practical use in 2015.
Nagoya University Professor Kazuya Takeda developed a technology to predict a risk from the
driver’s unnatural driving in alliance with Denso. While a man drives, the
mechanism records such data as speed, inter-vehicle distance, and acceleration.
When the drives starts to show driving with different characteristics, the
mechanism presumes the possibility of inattentive driving and drowsy driving. “This
technology can predict a risk three second beforehand,” Professor Takeda
said.
