Japanese Cars That Make Sense
Tuesday, October 30th, 2007How do you like the idea of talking to your cars? An idiotic idea? It isn’t.
You may call it an unnerving prospect. You may also call it almost impossible. But then again, it isn’t.
At the 40th Tokyo Motor Show, Japanese automakers flaunt their version of cars that really make sense. The fast-rising Japanese automakers wanted to prove more and they chose their home soil as their avenue to showcase their cream-of-the-crop cars.
Meet Nissan Motor Corp.’s Pivo2…
The concept car comes with a "robot agent" that can monitor a driver's emotions or physical condition through their facial expressions.
"For example, if the driver is surprised by another car cutting in, the robot agent can tell you, 'Don't worry, you're all right'," said Ken Mitamura, manager of the mobility laboratory at Nissan's research centre. "When you are sleepy, the robotic interface can detect it by monitoring a very slow pace of eye blinking and say, 'It's time to have a rest'.”
Nissan's researchers have worked on the development of the function for about a decade to make cars that are easier and less tiring to drive, Mitamura told the AFP.
Improving auto technology is the automakers’ way of boosting safety, parking and navigation systems. This is also their effort of driving away sales doldrums.
Never wanting to be upstaged, rival Toyota Motor Corp., which has developed similar technology, showcased a concept car with a focus on increased comfort thanks to seats that promises to help maintain good posture. Toyota RiN also has functions such as heated seats and an oxygen-level conditioner, as well as a heart monitoring system in the steering wheel, developed by affiliate Denso Corp.
When the driver grips the steering wheel, the system measures the electrical activity of the person's heart through electrodes on the surface of the wheel. "Because 90% of traffic accidents are said to be caused by human factors, carmakers are now looking to human bodies to improve safety functions," said Takashi Koumura, a senior researcher at Denso. "Detecting actual physical conditions like fatigue, drowsiness and irritation is the real challenge for us. It will probably take us at least five years to develop that sort of technology.”
Omron, a leading electronics maker, showcased its system to detect hand and eye movements with cameras and alert drivers when they take their eyes off the road.
Daihatsu, a minicar manufacturer, is aiming to tickle every motorist's dream — to make collisions a thing of the past. You might ask: What are they smoking in there? No, the people behind the company are not having pot sessions. So they have sound mind, no question about that.
"It's all the more important for our customers to avoid collisions because it's particularly dangerous for small cars to have crashes," said Daihatsu engineer Toshio Ito. The company’s 2 wide-angle laser radars and LED lamps detect vehicles that are on course for a smash. All at once, 3-dimensional images pop up in front of the driver to show information about the direction of impending obstacles.
But analysts are skeptical about the latest safety technology. "It's tricky for carmakers to commercialize those advanced safety functions," said Atsushi Kawai, an analyst at Mizuho Investors Securities.
“Those functions cannot guarantee 100 percent safety in driving a car. That means that once an accident happens it could cause product liability issues for carmakers. I'm sure carmakers are well aware that safety functions should serve only to complement, not to substitute for, drivers' ability to detect danger,” he concluded.
