车道偏离辅助系统技术现状与发展

Technology Status and Development of Lane Departure Assistant System

汽车车道偏离辅助系统的主要作用是实现汽车的横向主动安全,当汽车无意识偏离车道时,该系统将对驾驶员进行预警提示,并在必要时对汽车进行主动控制,使汽车保持在车道内以避免发生事故。文章介绍了车道偏离辅助系统的结构功能,对车道检测、驾驶员意图识别、车道偏离决策算法以及车道保持控制算法等关键技术的研究现状进行了分析总结,针对车道偏离辅助系统目前存在的研究局限和未来的发展方向,文章给出了改善建议和发展方向预测,为该系统的进一步研究提供了一定的参考。

The main function of lane departure assistance system is to realize the lateral active safety of the vehicle.When the car deviates from the lane unconsciously,the system will give warning to the driver and control the car actively when necessary,so as to keep the car in the lane and avoid accidents.The article introduces the structure and function of the lane departure assistance system,analyzes and summarizes the current research status of key technologies such as lane detection,driver intention recognition,lane departure decision algorithm and lane keeping control algorithm.The paper gives improvement suggestions and development direction prediction for the existing research limitations and future development direction of lane departure assistance system,which provides some reference for the further research of the system.
