The invention relates to the technical field of vehicle windows, in particular to vehicle window glass, a vehicle window assembly and a vehicle. The vehicle window glass provided by the invention is provided with a signal transmission area for a detection signal and an echo signal to pass through, and the signal transmission area has the transmittance of at least 75% for the detection signal incident at an incidence angle of 50-70 degrees; the number of spatial points scanned by each line of the detection signal each time is N, when the detection distance between the target object and the laser radar is 100 m, the echo signal received by the laser radar comprises at least X1 point cloud data, X1 > = N/200 and X1 > = 3, and N > = 400. The method can reduce the attenuation loss of the detection signal and the echo signal when the detection signal and the echo signal pass through the signal transmission area, enables the laser radar in the vehicle to receive enough point cloud data, achieves the high-precision recognition of a target object, and meets the triple use requirements of the laser radar for far-looking, clear-looking and stable-looking at the same time.
本申请涉及车窗技术领域,具体涉及车窗玻璃、车窗总成及车辆。本申请提供的车窗玻璃具有供探测信号和回波信号穿过的信号透过区,信号透过区对以50°~70°入射角入射的探测信号具有至少75%的透过率;探测信号的每条线每次扫描的空间点的数量为N,当所述目标物体与所述激光雷达之间的探测距离为100米时,所述激光雷达接收到的回波信号包括至少X1个点云数据,X1≥N/200且X1≥3,N≥400。本申请能够减少探测信号和回波信号在穿过信号透过区时的衰减损失,使位于车内的激光雷达接收到足够多的点云数据,实现对目标物体的高精度识别,从而同时满足激光雷达的看得远、看得清和看得稳的三重使用需求。
