The invention relates to an intelligent bus automatic driving stop-approaching management system, which comprises a UWB (ultra wide band) base station arranged around a stop and a UWB label arranged on a target vehicle; the UWB label sends a pulse signal to the UWB base station in the process that the target vehicle approaches the stop, the UWB base station receives the signal and responds to obtain the time difference of arrival between the UWB label and the UWB base station, calculates and obtains position coordinates of the target vehicle, acquires inertial navigation information of the target vehicle for combined positioning to obtain a driving state of the target vehicle, obtains a relative position between the target vehicle and a station according to the position of the station in a positioning area of a UWB base station, and generates a parking path in combination with the driving state of the target vehicle; and the target vehicle moves and parks according to the parking path. Compared with the prior art, the intelligent bus automatic driving stop-approaching management system has the advantages that the stopping precision and stopping efficiency of the bus are improved, and the safety of the automatic driving stopping process of the intelligent bus is guaranteed.
本发明涉及一种智能公交车自动驾驶靠站管理系统,包括设于车站周围的UWB(超宽带)基站以及设于目标车辆上的UWB标签,在目标车辆靠近车站的过程中UWB标签向UWB基站发送脉冲信号,UWB基站接收信号并进行应答,获得UWB标签与UWB基站之间的到达时间差,并计算得到目标车辆的位置坐标,同时采集目标车辆的惯导信息进行组合定位,得到目标车辆的行驶状态,并根据车站在UWB基站的定位区域的位置得到目标车辆与车站之间的相对位置,结合目标车辆的行驶状态生成停靠路径,目标车辆根据停靠路径进行移动、停放。与现有技术相比,本发明具有提高车辆的靠站精度和靠站效率,保证智能公交车自动驾驶靠站过程的安全性等优点。
