摘要
借助于MATLAB/Simulink软件建立汽车的模拟模型及其故障分析结构模型 ,作为汽车自诊断控制的算法进行系统故障检测和故障评价 ,并通过驾驶试验来验证汽车模型模拟的准确性 ;同时把试验信号贮存在控制单元中 ,进行功能和性能诊断试验 ,识别车辆系统恶化状况和判别车辆系统安全可靠性。为车辆动力电子控制系统稳定性的性能判断与评估提供了一个理论基础。
In this paper,a vehic le simulation model and its fault analysis structure model are set u p by means of MATLAB/Simulink,whic h are used for system faults detec tion and faults assessment.The accuracy of simulat ion is verified through driving te st.At the same time,the test signals ar e stored in the electronic control unit for carrying out the function and performance diagnostic test,so as to identify the deterioration s tate of vehicle system and to judg e the safety and reliability of ve hicle system.
