The invention discloses a V2V-based blind area lane change early warning method, and belongs to the technical field of intelligent network connection automobile driving active early warning. The method comprises the following steps: S1, acquiring vehicle information of an adjacent lane; S2, calculating the distance between vehicles; S3, judging blind area range early warning; S4, judging lane changing early warning; S5, judging blind area early warning; and S6, ending early warning. compared with the prior art, the method has the advantages that the information of other vehicles is obtained in a V2V mode, the correctness of the vehicle information is guaranteed, the accuracy of vehicle blind area early warning/lane changing early warning is improved, the system pleasure and comfort are improved, and the practicability of the vehicle blind area early warning/lane changing early warning system is guaranteed; the lane changing intention of a driver in the lane changing early warning system is considered, and the safety of the lane changing early warning system for judging whether the lane changing intention exists or not only by turning states of the steering lamps is improved; in addition, the response time and distance of the vehicle driver are considered, and an appropriate early warning opportunity for avoiding early warning in advance and too late early warning is achieved.
本发明公开了一种基于V2V的盲区变道预警方法,属于智能网联汽车驾驶主动预警技术领域。包括有步骤S1:获取临车道的车辆信息、S2:计算车辆间的距离、S3:盲区范围预警的判断、S4:换道预警的判断、S5:盲区预警的判断、S6:预警结束。相比于现有技术,本发明通过V2V方式获取得到他车信息,保证了车辆信息的正确度,提升了车辆盲区预警/变道预警的准确率,进而提升系统宜人性和舒适性,保证了车辆盲区预警/变道预警系统的实用性;其次,本发明考虑到变道预警系统中驾驶人换道意图,提升仅用转向灯转态来判断是否存在换道意图的变道预警系统的安全性;另外,本发明考虑车辆驾驶人的反应时间和距离,具备不提前预警、不过迟预警的适当预警时机。
