Technology:
New Energy and Industrial Technology Development Organization (NEDO) developed an automated
cruise technology that allows vehicles to trave in line. The technology
understands the running conditions through communications between vehicles and
adjusts the speed and inter-vehicular distance using computers. By keeping the
inter-vehicular distance that minimizes the air resistance between vehicles,
the research team reckons that fuel mileage will improve more than 15%.
Cameras and radars
loaded on vehicles decide the traveling course by recognizing the white line on
the road. The sensor attached to the front part of the vehicle understands the
speed and inter-vehicular distance. And the wireless and optical communications
with the vehicles before and after allows each vehicle to know their running
conditions. The computer adjusts the inter-vehicular distance automatically for
energy-saving travel. The running test was
conducted by three big trucks and one small truck. They realized the automated
cruise at 80 km/h with an inter-vehicular distance of 4 m.
