About

Hyo Whan Chang is a pioneering researcher in autonomous vehicle control and mobile robotics, with a particular focus on the intricate challenges of car-like vehicle navigation. His work addresses fundamental problems in nonholonomic systems—vehicles constrained by velocity limitations that make control especially complex. Chang’s most influential contribution, "Car parking control using a trajectory tracking controller" (2006, 34 citations), proposes an innovative parking control strategy combining an open-loop path planner with a trajectory tracking controller. This work is critical to the development of automatic parking assist systems, a key technology in modern automobiles. He further advanced the field with "Odometry calibration of a car-like mobile robot" (2007, 5 citations), where he identified and addressed systematic error sources specific to car-like mobile robots (CLMRs), offering a practical calibration method verified through experiments. While previous calibration techniques focused on two-wheeled robots, Chang’s research fills a crucial gap for four-wheeled, steering-controlled vehicles. His work remains foundational for engineers and researchers developing autonomous parking and navigation systems, demonstrating how precise control and calibration are essential for safe, reliable self-driving technology.
