摘要
汽车智能化、网联化的飞速发展带动了汽车电子化、智能化、集成化产业的发展,但与此同时,也带来了更加复杂的车内外电磁环境。车辆网联通信功能在复杂电磁环境下的可靠运行,轻则关乎用车舒适度,重则影响行车安全性。因此,网联车辆的电磁可靠性至关重要。然而实验室内完成汽车网联通信功能电磁可靠性测试离不开搭建网联仿真场景的检测设备。本文从保护网联车辆场景搭建测试设备在电磁干扰试验中的可靠性出发,设计方案进行摸底研究,分别在不同场强、不同频率、不同天线位置下,测试网联车辆检测设备端接收到的信号强度;并通过对测试数据进行分析处理,给出推荐测试布置,为后续网联车辆检测的完善化、标准化提供了一定的参考。
The rapid development of vehicle intelligence and networking has promoted the development of vehicle electronization,in⁃telligence and integration industry,but at the same time,it has also brought more complicated electromagnetic environment inside and out⁃side the car.The reliable operation of vehicle network communication function in complex electromagnetic environment is related to the comfort of vehicle and the driving safety.Therefore,the electromagnetic reliability of networked vehicles is very important.However,the electromagnetic reliability test of vehicle network communication function in the laboratory can not be completed without the detection equipment of network simulation scene.In this paper,from the perspective of protecting the reliability of networked vehicle scene construc⁃tion test equipment in electromagnetic interference test,the design scheme is thoroughly studied,and the signal strength received by net⁃worked vehicle detection equipment is tested under different field strengths,different frequencies and different antenna positions.By analyz⁃ing and processing the test data,the recommended test layout is given,which provides a certain reference for the improvement and standard⁃ization of the subsequent networked vehicle detection.
