摘　　要：智能网联汽车的发展对汽车制动系统提出了更高的要求,传统制动系统正逐步被线控制动系统所取代。线控制动系统以其卓越的响应速度和控制精度,成为实现高级别自动驾驶乃至无人驾驶的核心执行基础。系统性地回顾和总结了智能网联汽车线控制动系统的发展历程、架构、分类、关键技术及其应用;分析了不同类型线控制动系统的结构方案和优缺点,梳理与分析了主缸液压力控制、轮缸液压力控制、轮缸液压力估计、电磁阀控制以及夹紧力控制等关键技术,概述了基于线控制动系统的防抱死制动系统(ABS)和自动紧急制动系统(AEB)两种主动安全控制技术以及制动能量回收技术,分析和总结了智能网联汽车线控制动技术当前所面临的挑战与未来发展趋势。智能网联汽车线控制动技术正从电子液压制动系统(EHB)向电子机械制动系统(EMB)发展,但仍面临电机功率不足、电子元器件兼容性问题等诸多挑战,亟需提升系统的集成度和冗余性,以满足高级别自动驾驶的可靠性和安全性需求。The development of intelligent connected vehicles has placed higher demands on automotive braking systems,and traditional braking systems are gradually being replaced by brake-by-wire systems.With their out-standing response speed and control precision,brake-by-wire systems have become the core execution founda-tion for achieving high-level autonomous driving and even unmanned driving.This paper systematically reviews and summarizes the development history,architecture,classification,key technologies,and applications of the brake-by-wire systems for intelligent connected vehicles;analyzes the structural schemes and advantages and dis-advantages of different types of brake-by-wire systems,and combs and analyzes key technologies such as master cylinder hydraulic pressure control,wheel cylinder hydraulic pressure control,wheel cylinder hydraulic pressure estimation,solenoid valve control,and clamping force control.It also outlines two active safety control technolo-gies based on brake-by-wire systems:ABS and AEB,as well as brake energy recovery technology.It analyzes and summarizes the current challenges faced by intelligent connected vehicle brake-by-wire technology and its future development trends.The brake-by-wire technology for intelligent connected vehicles is evolving from EHB to EMB,but it still faces many challenges such as insufficient motor power and compatibility issues of elec-tronic components.There is an urgent need to improve the system’s integration and redundancy to meet the reli-ability and safety requirements of high-level autonomous driving.
