摘　　要：整车开发的工程设计阶段,在FEKO中对PEPS低频天线接口电路、天线参数、车内安装位置等输入建立仿真模型,仿真PEPS低频天线的工作有效性。通过仿真结果分析,优化天线在车内的布置以及低频天线标定电流,降低装车后天线检测失效的风险,减少后期工程更改的成本,节省研发时间。The simulation model is established based on the input of PEPS LF antenna interface circuits, antenna parameters, and fixing locations on the vehicle during the engineering design phase in FEKO. The working validity of PEPS LF antenna is simulated. The collocation and the value of rated current are optimized by analysis of the simulation results. So the risk of antenna failure fixed on vehicle is reduced to cut down the cost of engineering change at anaphase, and to save development time.
