The invention relates to the technical field of positioning, particularly provides an indoor parking lot vehicle positioning method and a vehicle searching method, and aims to solve the problem of how to realize vehicle positioning when no GPS signal exists. The indoor parking lot vehicle positioning method comprises the steps that after a vehicle is driven into a parking lot, whether the vehicle has positioning data or not is judged in real time; if the vehicle has the positioning data, obtaining the positioning data of the passing vehicle through a UWB ranging session with the passing vehicle in the driving process; and if the vehicle does not have the positioning data any more, obtaining the positioning data of the vehicle through UWB ranging session with other vehicles with the positioning data in the parking lot. According to the invention, a vehicle with positioning data is used as an anchor point of positioning reference, and a vehicle without positioning data obtains the positioning data of the vehicle, and obtains the positioning data of the vehicle through the relative position calculation based on the UWB ranging session; and the vehicle which obtains the positioning data becomes a new positioning anchor point, so that more vehicles can obtain own positioning data.
本发明涉及定位技术领域,具体提供一种室内停车场车辆定位方法及寻车方法,旨在解决无GPS信号时如何实现车辆定位的问题。本发明的室内停车场车辆定位方法包括:在车辆驶入停车场后,实时判断所述车辆是否具有定位数据;若所述车辆具有定位数据,通过与其行驶中途经车辆的UWB测距会话得到所述途经车辆的定位数据;若所述车辆不再具有定位数据,通过与所述停车场中具有定位数据的其它车辆的UWB测距会话得到自车的定位数据。本发明将带有定位数据的车辆作为定位参考的锚点,没有定位数据的车辆获取其定位数据,并通过基于UWB测距会话的相对位置计算获得自身定位数据;获得定位数据的车辆便会成为新的定位锚点,从而使更多的车辆的得到自己的定位数据。
