No. 692: An automated cruise technology to improve fuel mileage by more than 15% (February 27, 2013)

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.
