摘　　要：提出了一种汽车电子控制系统半实物仿真解决方案,以捷达1.6AT轿车为对象,采用半实物仿真技术通过硬件接口电路将实际车辆与模型环境有机结合,设计开发了汽车电控系统半实物仿真平台.所设计的平台在精确采集车辆传感器信号的同时能够实现车辆与半实物仿真模型间的实时数据交换;通过平台显示系统可以直观地观察车辆电控系统的工作过程及控制原理;并可根据需要合理地改变仿真模型的参数,对不同车型和不同使用工况进行仿真.该平台不仅解决了数学仿真对现实条件过于简化、建模难度大的问题,同时也克服了实物试验费用高、周期长的弊端,可将其应用于汽车电子控制系统的开发、调试、检测和教学试验等.The automotive electronic control system′s semi-physical simulation solution based on the Jetta 1.6AT car is proposed,and its semi-physical simulation platform is designed and developed combining the actual automotive with the model environment organically using hardware interface circuit by means of the semi-physical simulation.The platform designed can realize real-time data exchange between vehicles and hardware-in-the-loop simulation model as well as accurately capture vehicle sensor signals.The vehicle electronic control system′s work process and control principle can be observed visually through the platform display system.And according to the requirements,different models and different operating conditions are simulated by reasonably changing the parameters of simulation model.This platform not only solves the problem of real conditions simplification and modeling difficulty of mathematical simulation,but also overcomes high cost and long cycle of the physical test,and can be applied to the development,debugging,testing and teaching experiments of automotive electronic control systems.
