Analysis on Behaviors of a Driver in the System Failure in Forming Automatic Platooning of Trucks from Manual Driving

Abstract

In the project of Energy-saving Intelligent Transportation System (ITS) Technology of Japan, reliable automatic platooning by trucks is a main objective for highway transportation. The utilization of a driving simulator is useful to examine the safety of the automatic platooning by the Project. The driving simulator must be the same as an actual truck with software and hardware. Therefore, a new type of driving simulator was constructed to reproduce truck dynamics and control. A full-scale cabin of truck on a moving platform of six-degree-of-freedom was integrated into the driving simulator. To construct software architecture for automatic platooning, TruckSim as a general truck simulation software was embedded into Simulink, and a gap distance controller for longitudinal and lateral directions was designed. By the experiment using the driving simulator, on the assumption of system failure in forming automatic platooning of trucks from a manual drive or adaptive cruise control (ACC) to an automatic platooning of the truck, driver behaviors for the emergency avoidance in a following truck were studied.
