Establishment of stability control model of four-wheel drive electric vehicle and verification of model accuracy

基于CarSim/Simulink平台,搭建四轮驱动电动汽车联合仿真控制模型,在双移线工况下,验证所建立的四轮驱动电动汽车控制仿真模型的准确性,结果显示,所建立的四轮驱动电动汽车整车模型与CarSim里B级车模型性能具有高度一致性,这说明所搭建的四轮驱动电动汽车模型具有较高精确度,同时该模型的搭建也为后续的四轮独立驱动电动汽车稳定性控制奠定研究基础。

Based on the CarSim/Simulink platform, a four-wheel drive electric vehicle joint simulation control model is built. Under the condition of double line shifting, the accuracy of the control simulation model of the four-wheel drive electric vehicle is verified. The results show that the performance of the four-wheel drive electric vehicle model is highly consistent with that of CarSim B-class vehicle model, This shows that the four-wheel drive electric vehicle model has high accuracy, and the establishment of the model also lays a foundation for the stability control of the four-wheel independent drive electric vehicle.
