| 摘 要： | 柴油机整车动力学仿真模型是电控柴油机控制软件开发与测试的基础。本文应用实验分析和系统辨识的方法,以YC4D130电控柴油机台架试验为基础构建了发动机模型,并结合理论建模的方法,进一步构建了整车动力学仿真模型。经过试验车辆数据和MATLAB/Simulink仿真结果的对比,证实该模型可有效模拟车辆的行驶性能及换档过程,为柴油机控制策略的整车功能分析研究和设计验证提供了可靠的仿真平台。

| Abstract: | Development and testing of electronically controlled diesel engine control software is based on the diesel engine dynamics model.In this paper,diesel engine model is constructed by the experimental analysis of YC4D130 electronically controlled diesel engine bench test and the system identification methods.Combined with theoretical modeling,the diesel engine dynamics model is built.The comparison between the vehicle test data and the MATLAB/Simulink simulation results confirmed that the vehicle performance and shifting process can be effectively simulated by this dynamics model.It provides a reliable simulation platform for the function analysis and design verification of electronically controlled diesel engine control software. |
