Abstract:

In the context of the major trends toward electrification and intelligence in automobiles, the chassis system, which bears the core functions of vehicle driving, is undergoing a profound transformation from traditional mechanical chassis to x-by-wire chassis. The x-by-wire chassis, which uses electric power to operate and controls braking, driving, steering, and other functions through electrical signals, has great potential for the improvement of various aspects of automotive design, dynamics control, and intelligent driving and has become the focus of domestic and international competition. It is urgent to carry out a forward-looking layout of the x-by-wire chassis to achieve the continuous leadership of China’s new energy vehicle technology. This paper conducts a thorough analysis of the global development status of the x-by-wire chassis, systematically organizing the latest advancements and key technologies in its main subsystems, structures, and control areas. It examines and forecasts future trends in x-by-wire chassis development and also offers suggestions for its advancement based on current shortcomings and challenges in China’s x-by-wire chassis technology and industry.

Key words: x-by-wire chassis, chassis structure, chassis control, intelligent electric vehicles

摘要:

在汽车电驱动化和智能化大趋势下,承载汽车行驶核心功能的底盘系统正经历从传统机械式底盘到线控底盘的深度变革。利用电力作动且通过电信号操控制动、驱动、转向等功能的线控底盘对于汽车设计、动力学控制和智能驾驶等各方面的提升潜力巨大,成为国内外竞争焦点,亟需进行前瞻布局,以实现中国新能源汽车技术的持续引领。文章对底盘线控化发展的国内外现状进行了深入分析,系统梳理了底盘关键子系统、结构、控制领域的最新进展和关键技术,研判了未来线控底盘的发展趋势,结合当前中国线控底盘技术和产业存在的不足与挑战提出了发展建议。
