The embodiment of the invention relates to the technical field of intelligent driving, and particularly discloses a lane departure boundary judgment method and system. According to the embodiment of the invention, lane line parameter information of a lane where a vehicle is located is identified; calculating and obtaining lane line distance information and lane line collision time; setting a corresponding redundant alarm threshold value, comparing the lane line distance information and the lane line collision time with the corresponding redundant alarm threshold value, judging whether an alarm is needed or not, and when the alarm is needed, carrying out sound, visual and tactile alarm prompts on the vehicle; and performing lane departure return control on the vehicle, and canceling the alarm prompt after the lane departure return control is completed. According to the method, the boundary line of lane departure can be judged more accurately, the triggering accuracy of lane departure early warning and lane keeping functions is effectively improved, the function experience feeling of a driver can be improved, meanwhile, the safety and comfort of the vehicle can be improved, and development of the auxiliary driving function of the vehicle is facilitated.
本发明实施例涉及智能驾驶技术领域,具体公开了一种车道偏离的边界判断方法及系统。本发明实施例通过识别车辆所处车道的车道线参数信息;计算获取车道线距离信息和车道线碰撞时间;设置对应的冗余报警阈值,将车道线距离信息和车道线碰撞时间与对应的冗余报警阈值进行比较,判断是否需要报警,并在需要报警时,在车辆上进行声音、视觉和触觉的报警提示;对车辆进行车道偏离的回正控制,并在完成车道偏离的回正控制之后,取消报警提示。能够使车道偏离的边界线判断更加准确,有效提升了车道偏离预警和车道保持功能的触发准确度,可以使驾驶员的功能体验感提升,同时也可以提升车辆的安全性和舒适性,有利于汽车辅助驾驶功能的发展。
