Title: Multi-objective Optimal Defensive Driving Strategy for Autonomous Ground Vehicle in Mixed Traffic

Abstract: One of the challenges of autonomous ground vehicles (AGVs) is to interact with human driven vehicles in the traffic. This talk reports defensive driving strategies for AGVs in the mixed traffic. A novel multi-objective optimization algorithm for local trajectory planning is presented. The dynamic predictive control is used to derive optimal trajectories in a rolling horizon. The intelligent driver model and lane-changing rules are employed to predict the movement of the vehicles. The longitudinal terminal velocity and acceleration are taken as the design parameters. Multiple performance objectives are optimized simultaneously, including traffic safety, transportation efficiency, driving comfort and path consistency. The multi-objective optimization problem is solved with the cell mapping method. Different scenarios are created to test the effectiveness of the defensive driving strategies. Extensive simulations are carried out to validate the proposed defensive driving strategy. This study provides a framework for autonomous vehicles to interact with human drivers in the mixed traffic.

Bio: Dr. Jian-Qiao Sun earned his PhD from University of California at Berkeley in 1988.  He worked for Lord Corporation at their Corporate R&D Center in Cary, North Carolina, and since engaged in smart materials research and applications, and acoustic-structural controls.  In 1994, Dr. Sun jointed the faculty of the department of Mechanical Engineering at the University of Delaware as an Assistant Professor, was promoted to Associate Professor in 1998 and to Professor in 2003. He is currently a professor in School of Engineering at University of California, Merced.  He was an Associated Editor of ASME Journal of Vibration and Acoustics from 1994 to 2000, and was an Associated Editor of Communications in Nonlinear Science and Numerical Simulations from 2001 to 2012, an Editorial Board Member of Acta Mechanica Solida Sinica from 2003 to 2012, an Editorial Board Member of Journal of Vibration and Control since 2005 and Journal of Sound and Vibration since 2006. In October 2012, he started serving as the founding Editor-in-Chief of International Journal of Dynamics and Control published by Springer.  His research interests include cell mapping methods, multi-objective optimization, nonlinear random vibrations, nonlinear controls, active structural-acoustic control, stochastic systems, modeling and physical therapy applications of smart materials, time-delayed dynamical systems, and optimal HVAC control and fault detection of energy efficiency of office buildings.
