摘　　要：对电动汽车用双转子电机驱动系统进行简化建模,利用8自由度整车模型,通过仿真高速加速工况和低速加速工况,针对前驱和后驱车型双转子电机中内、外转子转动惯量不均衡对整车操纵稳定性的影响进行了分析。提出利用交叉四驱方式减少此种转动惯量不均衡造成的不良影响。仿真分析表明,四驱车型较前驱和后驱车型侧向稳定性显著提高。Firstly, a simplified model of the ADBRM was constructed. Then, using a 8 DOF vehicle model, the effect of imbalanced moment of inertia of intenal and external rotor of front-drive and rear-drive dual-rotor motor on vehicle handling stability based on high-speed acceleration and low-speed acceleration simulation is analyzed. The paper presents to use cross four-wheel drive mode to reduce the adverse effect caused by such imbalaneed moment of inertia. Simulation analysis indicates that the lateral stability of four-wheel drive vehicle is much better than that of front-drive and rear-drive vehicles.
