The invention discloses an automobile domain controller and an automatic mapping and positioning method for vehicles on a commuting road, the automobile domain controller comprises an SOC module, an MCU module, a serial port communication module and a cloud server, and the SOC module and the cloud server are respectively connected with the MCU module through the serial port communication module. The invention provides an automobile domain controller and a commuting road vehicle automatic mapping and positioning method, based on environment point cloud data collected by a vehicle-mounted laser radar on a daily intercommunication commuting road, the environment point cloud data is uploaded to a cloud end through an MCU chip of the domain controller, and the input feature vector is subjected to a random forest algorithm to obtain a target map. And a classification model is trained to locate the position of the vehicle on the road, so that the problem that part of high-precision maps far away from urban suburban roads cannot be updated in real time is solved.

    本发明公开了一种汽车域控制器及通勤道路上车辆自动建图和定位方法,所述汽车域控制器包括SOC模块、MCU模块、串口通信模块和云端服务器,所述SOC模块和云端服务器分别通过串口通信模块与MCU模块相连。本发明提供一种汽车域控制器及通勤道路上车辆自动建图和定位方法,基于每日往来通勤路上车载激光雷达收集的环境点云数据,通过域控制器的MCU芯片上传云端,通过随机森林算法对输入的特征向量,训练出分类模型来定位车辆在道路上的位置,解决部分远离城市郊区道路的高精度地图无法实时更新的问题。
