This book mainly discusses the key theoretical foundations, software and hardware design, core technologies, and integrated applications of intelligent connected vehicles. The theoretical foundation section covers vehicle system dynamics, driver behavior characteristics, traffic flow modeling, automatic control, machine learning, and data mining. The software and hardware design section introduces the design ideas and principles of intelligent connected vehicles from the perspectives of scene and function definition, system architecture, and electronic and electrical architecture. The core technology section discusses key technologies such as environmental perception, map positioning, decision planning, motion control, network communication, functional safety, and testing and evaluation. The integrated application section provides typical demonstrations and engineering applications of low-level assisted driving systems, high-level automated driving systems, vehicle infrastructure cooperative systems, and connected cloud control systems.
