车载网络硬件在环测试系统设计

Design of Loop Test System for In-vehicle Network Hardware

网络控制是汽车技术发展的趋势,网络性能分析与评价是车载网络系统设计与应用的前提。以客车车身网络控制为对象,设计了车载网络系统结构与功能模块;基于硬件在环技术,应用Vehicle Spy测试工具,设计了车载网络硬件在环测试系统;针对车载网络系统性能指标,分析和评价了系统网络特性,验证了测试系统的适用性。

Network control is the development trend of automobile technology, and the analysis and evaluation of the network performance are the prerequisite for design and application of the in - vehicle network system. Taking the vehicle body network control as the object, the module of structure and function for vehicle net- work system are designed. On the basis of the loop technique of hardware, the loop test system of hardware for vehicle network is designed by the test tool of Vehicle Spy. According to the performance of vehicle network system, the network characteristics of the system is analyzed and evaluated, moreover, the applicability of test system is verified.
