The invention provides an automatic positioning method and system for power conversion of a heavy truck, which are used for automatically positioning the heavy truck when the heavy truck needs to be subjected to power conversion in a power conversion station, the heavy truck is provided with a UWB label, and each power conversion area of the power conversion station is provided with a UWB base station. The method comprises the steps that S1, a UWB base station of a battery replacement area is connected with a UWB label on a vehicle to be subjected to battery replacement entering the area of the UWB base station, and the position of the vehicle to be subjected to battery replacement is calculated through a UWB system; s2, calculating the battery position of the to-be-replaced vehicle according to the position of the to-be-replaced vehicle and the model of the to-be-replaced vehicle; and S3, judging an error between the battery position of the to-be-replaced vehicle and the position requirement of the battery replacing station on the battery, and when the error is greater than a preset threshold value, starting a vehicle automatic driving function to move the vehicle until the battery position of the to-be-replaced vehicle meets the position requirement of the battery replacing station on the battery.

    本发明提供一种用于重卡换电的自动定位方法及系统,用于在重卡需要在换电站进行换电时对其进行自动定位,其中,所述重卡配置有UWB标签,所述换电站的每个换电区域配置有UWB基站,所述方法包括:S1、换电区域的UWB基站连接进入其区域内的待换电车辆上UWB标签,并采用UWB系统计算待换电车辆的位置;S2、根据待换电车辆的位置、待换电车辆型号计算待换电车辆的电池位置;S3、判断待换电车辆的电池位置与换电站对电池的位置要求之间的误差,并在误差大于预设阈值时启动车辆自动驾驶功能对车辆进行移动直至待换电车辆的电池位置满足换电站对电池的位置要求。
