摘要 基于操纵稳定性研究,建立了Carsim/Simulink联合仿真的分布式驱动电动汽车整车模型。阐述了分布式电驱动系统与整车的接口设置方法以及建模所需关键参数的辨识方法,包括车辆横摆转动惯量、滚动阻力与空气阻力特性、转向系统传动比、轮胎非线性侧偏特性等参数,并通过方向盘转角阶跃输入实验与蛇形实验验证了模型的准确性,为分布式驱动电动汽车操纵稳定性研究提供了精确可靠的仿真平台。 A simulation model of distributed drive electric vehicle handling and stability based on co-simulation of Carsim/Simulink was established. In order to complete the co-simulation, interface settings of distributed electric drive system and vehicle was configured properly. Then methods of identifying necessary parameters required for modeling were described, including inertia of yaw moment, rolling resistance and air resistance, steering ratio, nonlinear cornering behavior of tires, etc. By step angle input of steering wheel test and slalom test, the accuracy of vehicle model was verified. An accurate and reliable simulation platform for the research of distributed drive electric vehicle handling and stability was provided.
