摘　　要：文章针对总线型车身控制系统的设计问题,提出了一种硬件在环仿真解决办法。首先采用规则化方法描述原型系统的控制意图,然后融合虚拟现实和物理测试2种仿真手段的优点,设计了分布式硬件在环仿真系统,用于模型控制逻辑的推演和车身部件响应延时特性检测,最后以电控刮水器子系统作为典型实例进行了仿真验证。实验数据表明,该方法可以有效验证功能需求模型,量化评估模型的时延误差,从而提高了车身控制系统的开发效率。Aiming at the design of bus-based automotive body control system,a method of hardware-in-the-loop simulation（HILS） is put forward in this paper.The rule description method is used to describe the control intention of prototype model.Then a distributed HILS system,which integrates the two simulation methods of virtual reality and physical test,is designed.The HILS system can derive the model control logic and test the response delay characteristic of automotive body.An electric windshield wiper sub-system is used as a typical case to testify the simulation system.The experimental results show that the proposed approach can verify the functional requirement model,quantify the time delay of the evaluation model,and improve the development efficiency of body control system.
