How Control Engineering is Shaping the Future of Self-Driving Cars

What is it about?

The study focused on advancing intelligent and connected vehicles (ICVs) by exploring the role of control engineering in optimizing autonomous vehicle performance through advanced control techniques. The methodology included investigating control techniques such as Kalman filtering for multisource data fusion, which optimally integrates data from various sensors despite their individual limitations. Additionally, robust and adaptive estimation methods, like the extended state observer (ESO), were developed to estimate unknown states and manage model uncertainties. The study also incorporated neural-based observers (NBOs) using neural networks to enhance the ESO structure for complex system models. Communication and sensing capabilities were integrated to achieve desired vehicle states and decision-making processes. The research concluded with a focus on achieving both local and global optimization through dynamic system modeling and neural networks, highlighting significant developments in control engineering for autonomous vehicles.
