摘　　要：在研究现有混合动力驱动系统的基础上,提出一种基于双转子电动机的机一电桥间混合四轮驱动系统。该系统由机械桥和电动桥构成,通过桥间动力综合控制,两桥可以单独或共同驱动车辆行驶,其中电驱动桥由双转子电动机加上减速换向机构组成,可以实现驱动、差速、能量回收等功能。在分析双转子电动机工作原理的基础上,建立其数学模型,并进行模拟负载突变及车辆转弯下的性能仿真。以某运动型多功能汽车为例,利用Matlab/Simulink软件进行原型车和新方案的对比性能仿真。仿真表明:在保持动力性相当的前提下,新混合动力方案在经济性方面有较好的改善,百公里油耗比原型车在高速、城市工况下能够分别下降10.58%、21.87%。The existing hybrid driving systems are studied. One kind of hybrid four wheel driving system is brought forward that is based on dual-rotor electric motor. This system is composed of mechanical transaxle and electric transaxle. By synthetically controlling of the two transaxles, the vehicle can be driven by either one or both of the two transaxles. The electric transaxle is composed of one dual-rotor electric motor and reducer and rotation direction exchange devices. It has the ability of driving, differencing and energy feedback. On the basis of performance theory of the dual-rotor electric motor, the mathematic model is established. Furthermore, the simulations of load mutation and swerve are carried out. Taking some sport utility vehicle as an example, the comparison simulation between prototype and novel type vehicle is done on the Matlab/Simulation calculating platform. The simulating results show that the driving performance of the novel vehicle is also the same as the prototype vehicle and the fuel economy is better than the prototype vehicle. The fuel consumption of the novel vehicle is 10.58% and 21.87% less than the prototype vehicle per 100 km based on the highway and city running cycle.
