摘　　要：电子机械制动系统(electro-mechanical brake system,EMB)采用电控纯机械制动技术,可实现多种主动安全控制功能,具有结构精简、响应迅速,能够对车轮制动力矩进行独立精确控制等优势。为全面梳理EMB系统的发展现状,明确其未来技术走向,本文首先介绍了EMB的组成架构,分析了EMB典型结构型式的优缺点并确定了相关内容的主要研究方向。然后从夹紧力控制和传感器故障诊断两个层面分别对国内外的研究进展展开综述;分析了夹紧力控制算法的发展历程及未来研究重点,对比了3种典型夹紧力控制算法的试验效果;接着介绍了传感器故障诊断的具体类型及作用,通过定量化的指标分析不同故障诊断算法的实际控制效果。最后对EMB系统所面临的问题及未来发展趋势进行了分析和展望,指明了进一步的研究可以集中在夹紧力控制和传感器故障诊断等算法准确性和鲁棒性的提高、EMB与线控底盘集成控制技术的协调控制以及EMB对整车稳定性和舒适性的影响等方面。The electro-mechanical brake system(EMB)uses electronic control pure mechanical braketechnology to realize various active safety control functions. It has the advantages of simple structure,rapid re-sponse,independent and precise control of wheel braking torque. To comprehensively sort out the development sta-tus of the EMB system and clarify its future technology trend,the structure of the EMB is introduced first,and theadvantages and disadvantages of several typical structure types of the EMB are analyzed and main research direc-tions in the future are determined. Then,the research progress at home and abroad is reviewed from two levels ofclamping force control and sensor fault diagnosis. The development history and the focus of future research of clamp-ing force control algorithms are analyzed,and the experiments’ results of three typical clamping force control algo-rithms are compared.Then,the specific types and functions of sensor fault diagnosis are introduced,and the actualcontrol effect of different fault diagnosis algorithms is analyzed through quantitative indicators. Finally,the prob-lems faced by the EMB system and future development trends are analyzed and prospected. It is pointed out that fur-ther research can be concentrated on improving the accuracy and robustness of algorithms of clamping force controland sensor fault diagnosis,etc.,the coordinated controlling of the EMB and wire-controlled chassis integrated con-trol technology and the influence of the EMB on the stability and comfort of the vehicle.
