The invention relates to the technical field of vehicle positioning, and discloses a vehicle searching method and system, and the method comprises the steps: transmitting a vehicle searching request for indicating the searching of a target vehicle through a target user terminal, and transmitting a pulse vehicle searching signal for searching the target vehicle through an intermediate vehicle in a UWB communication range after the intermediate vehicle receives the vehicle searching request, the method is not influenced by a network environment and a positioning signal, and is high in stability and anti-interference performance. The intermediate vehicle emitting the pulse vehicle searching signal receives return information from other intermediate vehicles in the UWB communication range of the intermediate vehicle, and if the return information indicates that other intermediate vehicles are target vehicles, the target vehicle is determined to be searched; and if the returned information indicates that other intermediate vehicles are not the target vehicle, the intermediate vehicle sending the pulse vehicle searching signal indicates other intermediate vehicles to execute vehicle searching operation, so that the vehicle searching distance and range of the user are expanded, and the vehicle searching success probability is improved until the target vehicle is searched.
本发明涉及车辆定位技术领域,公开了寻车方法及寻车系统,本发明利用目标用户终端发出用于指示寻找目标车辆的寻车请求,在其UWB通信范围内的中间车辆接收到寻车请求后,该中间车辆发送用于寻找目标车辆的脉冲寻车信号,不受网络环境以及定位信号的影响,稳定性和抗干扰性强。发出脉冲寻车信号的中间车辆从自身UWB通信范围内的其他中间车辆接收返回信息,若返回信息指示其他中间车辆是目标车辆时,确定寻找到目标车辆;若返回信息指示其他中间车辆不是目标车辆时,发出脉冲寻车信号的中间车辆指示其他中间车辆执行寻车操作,扩大用户寻车的距离和范围,以便提高寻车成功的概率,直到寻找到目标车辆。
