The disclosure provides use of UWB radio to execute a pedestrian-vehicle rendezvous. The disclosure pertains to using ultra-wideband (UWB) radio communications to execute a pedestrian-vehicle rendezvous. In one example operation, a personal device such as a smartphone, is used to identify a location of a vehicle with a first level of accuracy. For example, the smartphone may be used by a pedestrian to obtain GPS location coordinates of a ride-hail vehicle summoned by the pedestrian. The vehicle may be located relatively far from the pedestrian. The smartphone may be configured to automatically establish a UWB radio link with a UWB transponder in the vehicle and/or a smartphone carried by a driver of the ride-hail vehicle, when the vehicle is within range to establish UWB communications. The UWB radio link may be used to execute one or more of various procedures to locate the vehicle with a second level of accuracy that is higher than the first level of accuracy.
本公开提供了“使用UWB无线电执行行人‑车辆会合”。本公开涉及使用超宽带(UWB)无线电通信来执行行人‑车辆会合。在一个示例性操作中,个人装置(诸如智能电话)用于以第一准确度水平识别车辆的位置。例如,行人可以使用智能电话来获得由行人召唤的约车车辆的GPS位置坐标。车辆可以位于距行人相对较远的位置。智能电话可以被配置为当车辆在用于建立UWB通信的范围内时与车辆中的UWB应答器和/或由约车车辆的驾驶员携带的智能电话自动建立UWB无线电链路。UWB无线电链路可用于执行各种程序中的一种或多种来以高于第一准确度水平的第二准确度水平定位车辆。
