Truck trains studied with lead cab controlling ones behind with radar

THE feasibility of truck trains are being studied by the American Transportation Research Institute (ATRI), the US Department of Transportation and the American Trucking Associations.

Vehicle-to-vehicle (V2V) technology involves a forward-looking radar to control the spacing between vehicles, with speed and braking control delegated to the lead vehicle.

Braking and other operational data is constantly exchanged between trucks, allowing for continuous adjustment. Drivers would still be required in both vehicles, who take back control if necessary.

ATRI and the DOT researchers are doing cost/benefits studies of "Driver Assistive Truck Platooning" which allows a lead truck to control a second one to improve fuel efficiency and safety.

Input from drivers and trucking companies on the concept is wanted on the results of tested run on one truckload carrier, reports Newark's Journal of Commerce.

The National Highway Traffic Safety Administration (NHTSA) issued an advanced notice of proposed rulemaking this summer that could lead to a mandate for certain vehicle to vehicle (V2V) technologies in light vehicles.

The concept and its underlying V2V technology are among several ideas, including autonomous, driverless trucks, being floated as a means of improving efficiency and productivity.

Peleton Technology and truckload carrier CR England demonstrated such a system late last year in Utah, "platooning" pairs of trucks travelling on Interstate 80 at 64 miles per hour.

"The safety systems are always active, and when the trucks are out on the open road, they can form close-formation platoons," Peleton said on its website.

"The system controls braking and acceleration, similar to adaptive cruise control, and drivers remain fully engaged and retain steering control."The reduction in aerodynamic drag in these platoons provides "unprecedented fuel economy savings" for the trailing and leading truck, Peleton said.
