Theoretical and experimental research on the double lane change maneuver

Abstract

A virtual double lane change test procedure is proposed based on the NATO AVTP 03-160W requirement. This test procedure simulates an emergency maneuver that determines the vehicle's dynamic stability and decisively influences road safety, being one of the most applied methods of performance evaluation. Using Trucksim modeling and simulation software, the virtual vehicle model and test procedure were established. The experimental data obtained with FED Alpha vehicle helped to validate both models. For this purpose, the vehicle dynamic responses such as steering wheel angle, vehicle lateral acceleration, yaw velocity and roll angle were comparatively analyzed. Important and valid conclusions concerning the optimization of the vehicle’s dynamic behavior were drawn. Ultimately, a methodology to predict the maximum speed to successfully pass double lane change is proposed.
