整车坏路可靠性试验的无人化技术研究

Research on Driverless Technology Based on Bad Road Reliability Test

为缩短整车坏路可靠性试验周期,提出了一种无人化测试方法,基于实时动态(RTK)载波相位差分技术与惯性测量单元(IMU)的组合导航方案进行循迹行驶,采用多传感器融合进行障碍物感知,运用云端平台进行远程控制,并利用某款纯电动车型完成了原型机开发,实现了以自动驾驶的方式开展强化坏路试验。

To shorten the period of vehicle bad road reliability test,this paper proposes an unmanned test method,which uses an integrated navigation scheme based on Real-Time Kinematic(RTK)carrier phase difference and the Inertial Measurement Unit(IMU)for tracking drive and obstacle perception with multiple sensor fusion,it also uses the cloud platform for remote control,in addition,it completes the prototype development based on a battery electric vehicle.Bad road reinforced test is completed by automated driving.
