基于Roadbox设备泊车VIL性能开发

VIL Performance Development Based on Roadbox Equipment Parking

文章主要描述一种基于Roadbox设备搭建的自动泊车VIL测试平台;采用虚拟车辆上配置的虚拟探头探测场景中障碍物距离信息,通过Roadbox机箱中的超声波仿真板卡将距离信息转换成电平信号,再由超声波换能器产生超声波,进而被真实传感器探头接收到,传给实车上APA控制器,控制车辆运动。真实车辆运动情况由IMU通过CAN线传给虚拟车辆,进而驱动虚拟车辆随着真实车辆的运动,完成泊车过程。

This article mainly describes an automatic parking VIL test platform based on Roadbox equipment.Detect obstacle distance information in virtual scene by virtual probe of virtual vehicle in the virtual scene,and then convert the distance information to level signal by ultrasonic simulation board card in Roadbox,and then converted to the ultrasonic wave,which is generated by the ultrasonic transducer to be received by the real sensor probe,finally pass to the real car APA controller to control the vehicle movement.The real vehicle movement is transmitted by IMU to the virtual vehicle through CAN line,and then drives the virtual vehicle to complete the parking process in the virtual scene along with the movement of the real vehicle.
