| 摘 要： | 针对目前单轴并联式(ISG)混合动力系统转矩响应慢和能量回收效率低等不足,提出一套新型的混合动力总成方案。该方案采用较大功率的电动机,在发动机与电机间安装1个电控自动离合器,电机与变速器之间安装1个手动离合器。根据汽车动力学理论计算车辆在中国典型城市的道路动力需求,建立瞬态工况下双离合器ISG混合动力汽车的Simulink仿真模型,并针对汽车的瞬态加速工况,通过离合器来协调转矩的分配。仿真及实验结果表明:采用该方案改善了状态切换过程的平顺性,提高了瞬态过程中的转矩响应速度,缩短了加速耗时。

| Abstract: | Based on the fact that the single axis parallel hybrid systems in torque response is late and energy recovery efficiency is low,a set of new hybrid power scheme was proposed.This scheme adopted a higher power of the motor and an electric automatic clutch between the engine and motor,a manual clutch was fixed between motor and transmission.Based on the theory of vehicle dynamics in typical Chinese urban roads and so on,many kinds of needed motivations were calculated,and a simulink model of the double-clutch... |
