The invention discloses an automatic driving deviation correction control method and system, and relates to the technical field of automatic driving, and the method comprises the steps: carrying out the comparative analysis of a dynamically monitored real-time automatic driving path of a target vehicle and a predetermined automatic driving path, and obtaining a target deviation coefficient; reading a predetermined road condition feature, and extracting a first road condition feature; obtaining a first real-time characteristic parameter; extracting a first historical driving record in the historical driving vehicle log; obtaining a first prediction feature parameter; taking a mean value and recording the mean value as a first target parameter; and activating the deviation rectification control decision model to obtain a deviation rectification control decision of the target vehicle on the target road section. The technical problems that in the prior art, an automatic driving vehicle is difficult to deal with driving path deviation caused by dynamic road condition changes, then the driving track cannot be corrected in real time, and the automatic driving path control precision and stability are insufficient are solved, and the technical effect of improving the path control precision and stability of the automatic driving vehicle is achieved.

    本发明公开了一种自动驾驶的纠偏控制方法及控制系统,涉及自动驾驶相关技术领域,该方法包括:将动态监测到的目标车的实时自动驾驶路径与预定自动驾驶路径进行对比分析,得到目标偏移系数;读取预定路况特征,并提取第一路况特征;得到第一实时特征参数;提取历史行驶车辆日志中的第一历史行车记录;得到第一预测特征参数;取均值记作第一目标参数;激活纠偏控制决策模型对得到目标车在目标路段的纠偏控制决策。解决了现有技术中存在的自动驾驶车辆难以应对动态路况变化导致的驾驶路径偏移,进而驾驶轨迹无法实时修正,使得自动驾驶路径控制精度和稳定性不足的技术问题,达到了提升自动驾驶汽车的路径控制精度和稳定性的技术效果。
