The invention discloses an XGBoost algorithm-based vehicle lane changing driving behavior decision-making method. The method comprises the following steps of S1, acquiring motion state information of a vehicle and vehicles around the vehicle by adopting a V2X technology and a vehicle sensor; s2, the obtained motion state information of the vehicle and the vehicles around the vehicle is input into a parameter processing module for data conversion, and vehicle relative motion state parameters of the vehicle and the vehicles around the vehicle are obtained; and S3, inputting the relative motion state parameters of the vehicle and the speed of the vehicle into a vehicle autonomous lane changing decision model based on an XGBoost algorithm, and outputting a lane changing decision result. The intelligent networking technology is used for obtaining the motion state information of the vehicle beside the vehicle, the motion state information of the surrounding vehicle is monitored in real time, the accuracy of the obtained data is improved, the decision-making method serves as a vehicle autonomous lane changing decision-making model based on an integrated learning method of the XGBoost algorithm, the decision-making time is short, and the accuracy of the decision-making result is high.

    本发明的一种基于XGBoost算法的汽车换道驾驶行为决策方法,包括如下步骤:S1.采用V2X技术与车辆传感器获取自车与自车周围车辆的运动状态信息;S2.将获取的自车与自车周围车辆的运动状态信息输入参数处理模块中进行数据转换,得到自车与自车周围车辆的车辆相对运动状态参数;S3.将车辆相对运动状态参数与自车速度输入到基于XGBoost算法的车辆自主换道决策模型中,输出换道决策结果。本发明使用智能网联技术获取车边车辆运动状态信息,对周边车辆的运动状态信息进行实时监测,提高获取的数据准确性,本发明的决策方法基于XGBoost算法的集成学习方法作为车辆自主换道决策模型,决策时间短,决策结果准确率高。
