摘　　要：气动换挡系统用于减轻汽车驾驶员的换挡力、提高车辆换挡平顺度,是提升汽车安全性的重要环节。现有气动换挡系统存在气动故障多发、人机耦合性差和换挡控制精度低等问题,在汽车换挡过程中易发生由人机对抗引起的换挡卡滞与错位,导致换挡失效,甚至引发严重的行车事故。通过分析国内外在气动换挡系统故障诊断与气动换挡控制系统等方面的研究现状,指出目前我国在气动换挡系统的故障诊断能力与气动换挡系统依从性与柔性控制方面现存问题和未来发展趋势,为我国高效气动换挡控制系统与故障实时诊断技术的发展提供参考。Pneumatic shift system is used to reduce the driver's shifting force and improve the vehicle's shifting smoothness,which is an important link to improve vehicle safety.The existing pneumatic shift system has many problems,such as multiple pneumatic failures,poor man-machine coupling and low gear shift control precision.In the process of shifting,it is easy to have the shift stick and dislocation caused by man-machine confrontation,which leads to the shift failure and even leads to serious driving accidents.This paper analyzes the research status of pneumatic shift system fault diagnosis and pneumatic shift control system at home and abroad,and points out the existing problems and future development trends in the fault diagnosis ability of pneumatic shift system,compliance and flexible control of pneumatic shift system,which provides reference for the development of efficient pneumatic shift control system and real-time fault diagnosis technology.
