The invention relates to a lane keeping device, method and system, and an automobile. The lane keeping device comprises a lane detection unit and an LKA electric control unit; The lane detection unitoutputs a first lane line confidence coefficient, first lane line information, a second lane line confidence coefficient and second lane line information; the LKA electric control unit selects and processes the first lane line information or the second lane line information based on the first lane line confidence coefficient and the second lane line confidence coefficient to obtain steering data;and the steering data are transmitted to an electric power steering system so as to carry out transverse control on the vehicle. The problem that a traditional lane keeping assist (LKA) scene is limited, for example, a camera may not detect a lane line at night or when the lane line is not clear, triggering faults of an LKA function, frequent quitting and entering are caused is solved, and then the actual use scene and flexibility of the LKA are expanded.
本申请涉及一种车道保持装置、方法、系统及汽车,其中,车道保持装置包括车道检测单元和LKA电控单元;车道检测单元输出第一车道线置信度和第一车道线信息,第二车道线置信度和第二车道线信息;LKA电控单元基于第一车道线置信度与第二车道线置信度,选取第一车道线信息或第二车道线信息进行处理,得到转向数据;并将转向数据传输给电动助力转向系统,以进行车辆的横向控制。本申请解决了传统车道保持辅助系统(LKA)场景受限问题,如夜晚或者车道线不清晰时摄像头可能无法检测到车道线,导致LKA功能的触发故障、以及频繁退出和进入,进而扩大LKA的实际使用场景和灵活性。
