The invention discloses a vehicle continuous lane change risk early warning method and system based on a predicted trajectory, and belongs to the technical field of vehicle driving safety, the risk early warning method comprises the following steps: S1.1, collecting vehicle information to obtain vehicle information data, and predicting the driving intention of a vehicle according to the collected data; s1.2, acquiring a vehicle lane changing information data set by collecting vehicle lane changing information, and performing driving style identification according to the collected data set; s2, acquiring an environment information data set by collecting environment information, and performing trajectory prediction according to a driving intention result, a driving style and the environment information data set to obtain a future trajectory; and S3, risk level prediction is carried out according to the predicted future trajectory, and early warning release is carried out according to the risk level. The problems that an existing early warning system is difficult to apply to continuous lane changing scenes, low in accuracy and precision, incapable of predicting in advance and difficult to early warn in advance in the future are solved.
本发明公开了一种基于预测轨迹的车辆连续换道风险预警方法及系统,属于车辆驾驶安全技术领域,所述风险预警方法包括:S1.1,通过对车辆自身信息进行收集,得到车辆信息数据,根据收集的数据对车辆进行行驶意图预测;S1.2,通过收集车辆换道信息得到车辆换道信息数据集,根据收集的数据集进行驾驶风格识别;S2,通过收集环境信息,得到环境信息数据集,根据行驶意图结果、驾驶风格、以及环境信息数据集进行轨迹预测得到的未来轨迹;S3,根据预测的未来轨迹进行风险等级预测,依据风险等级进行预警发布。解决目前预警系统难以针对连续换道场景的应用以及准确率低、精度低,不能提前预测未来难以提前预警的问题。
