The invention provides a UWB-based vehicle searching guiding method and a related device, and the method comprises the steps: receiving a UWB signal transmitted by a UWB anchor point disposed on a vehicle based on a UWB module, and obtaining a first relative distance parameter according to the UWB signal; when the first relative distance parameter is in a first distance range, the information of the direction where the vehicle is located is determined in combination with UWB signals sent by the UWB anchor points; when the first relative distance parameter is in a second distance range, relative position information is determined in combination with UWB signals sent by the UWB anchor points, and the maximum distance parameter in the second distance range is smaller than the minimum distance parameter in the first distance range; and outputting vehicle searching guide information based on the direction information or the relative position information of the vehicle. According to the invention, the UWB technology which is high in penetrating power and good in anti-multipath reflection effect is adopted for vehicle searching guiding, the positioning precision is high and the robustness is good in an application scene of a shielded parking lot, and the effectiveness of vehicle searching guiding is ensured.

    本申请提供了一种基于UWB的寻车引导方法及相关装置,基于UWB模组接收车辆上配置的UWB锚点发送的UWB信号,根据UWB信号获取第一相对距离参数;当第一相对距离参数处于第一距离范围时,结合多个UWB锚点发送的UWB信号确定车辆所处方向信息;当第一相对距离参数处于第二距离范围时,结合多个UWB锚点发送的UWB信号确定相对位置信息,其中,第二距离范围中最大距离参数小于第一距离范围中最小距离参数;基于车辆所处方向信息或相对位置信息输出寻车引导信息。本申请采用穿透力强、抗多径反射效果好的UWB技术进行寻车引导,在有遮挡的停车场应用场景下的定位精度较高,鲁棒性好,保证了寻车引导的有效性。
