Abstract: In the context of global climate change and energy crises, new energy vehicles have become crucial for addressing environmental pollution and energy shortages. This paper explores the innovative applications of intelligent electronic control technology in the chassis systems of new energy vehicles. By analyzing the basic principles of electronic control technology and citing typical application cases, the paper provides a detailed introduction to the key technologies and innovations of intelligent electronic steering systems, intelligent electronic braking systems, and intelligent electronic suspension systems. Furthermore, through theoretical modeling and simulation verification, the paper analyzes the significant advantages of electronic control technology in enhancing vehicle maneuverability, safety, comfort, and energy efficiency. With the continued development of electronic information technology and control theory, intelligent electronic control technology will be more widely and deeply applied in the chassis systems of new energy vehicles.
