摘　　要：简要介绍一款四驱混合动力汽车的基本结构,并且根据汽车行驶的转矩需求,详细论述了不同工作模式下汽车的各个动力部件的转矩分配以及混合动力汽车在模式切换时,各个控制器及动力部件之间的协同工作情况。提出了由ISG电机和后驱电机进行转矩补偿的转矩协调控制策略,以改善汽车的驾驶性能。最后在Matlab/Simulink中搭建了前向式仿真模型,对汽车的转矩分配策略以及转矩协调策略进行了仿真。仿真结果表明,该控制策略是有效的、可行的。The basic layout of the car is introduced briefly, and the torque distribution method under different working modes is discussed according to the torque request of the car. In addition, the coordinative working situation of the power components and their controllers when mode changes is in- troduced. In order to improve the driving performance of the vehicle, the coordinative control strategy in which the ISG motor and rear motor compensate the torque is put forward. At last, a forward model is built in Matlab/Simulink, and the torque distribution and coordination control strategy is simulated. The results indicate that the control strategy put forward in this paper is effective and applicable.
