The invention discloses an automatic precise lane changing system and method for a double-vehicle scene, and relates to the technical field of automatic driving testing. Two positioning antennas; the two communication processing modules are arranged on the main vehicle and the target vehicle respectively, each communication processing module is connected to the corresponding ADCU controller and the corresponding positioning antenna, and the two communication processing modules can communicate with each other; the communication base station and the two positioning antennas reflect positioning coordinates of double vehicles to the two communication processing modules in real time, and the two communication processing modules jointly calculate the longitudinal distance between the double vehicles in real time according to the positioning coordinates of the double vehicles and send the longitudinal distance to the ADCU controller of the target vehicle. And the ADCU controller of the target vehicle triggers steering and lane changing when the longitudinal distance is equal to the test distance. According to the automatic accurate lane changing system and the lane changing method, when the longitudinal distance is equal to the test distance, the steering lane changing operation can be accurately triggered, and the lane changing process is accurately executed according to the preset track.

    本申请公开了一种双车场景的自动精准换道系统及换道方法,涉及自动驾驶测试技术领域,包括:通讯基站;两根定位天线;两个分别设置于主车和目标车的通讯处理模块,每个通讯处理模块分别连接于各自的ADCU控制器和定位天线,两个通讯处理模块能够相互通讯;所述通讯基站和两根定位天线实时向两个通讯处理模块反映双车的定位坐标,两个通讯处理模块联合根据双车定位坐标实时计算双车的纵向间距并发送给目标车的ADCU控制器,所述目标车的ADCU控制器在纵向间距等于测试间距时触发转向换道。本申请的自动精准换道系统及换道方法,能够在纵向间距等于测试间距时,精准触发转向换道操作,并按照预设轨迹精准执行换道过程。
