不同轮胎模型对于ESP仿真性能影响分析

Analysis on the Influence of Different Tire Models on ESP Simulation Performance

为研究不同轮胎模型对ESP(Electronic Stability Program)仿真性能影响,选取当前ESP仿真常用的轮胎模型进行对比分析。分别选取理论轮胎模型Gim模型、经验轮胎模型Magic Formula模型以及半经验半理论轮胎模型Dugoff模型。通过使用MATLAB/Simulink搭建七自由度整车模型、不同轮胎仿真模型以及参考模型,并与Car Sim联合进行J-转向仿真试验。结果表明,Dugoff轮胎模型更符合ESP仿真试验的要求。

In order to study the influence of different tire models on ESP（Electronic Stability Program） simulation performance,the tire models commonly used in ESP simulation were chosen to make an analysis and comparation. The theoretical tire model Gim model, the empirical tire model Magic Formula model and the semi empirical and semi theoretical tire model Dugoff model were selected respectively. Through the use of MATLAB/Simulink, seven degrees of freedom vehicle model, different tire simulation model and reference model were built, and joint J-steering simulation test was performed with CarSim. The results show that Dugoff tire model is more in line with the requirements of the ESP simulation.
