| 摘 要： | 为实现混合动力电动汽车纯电动模式与发动机工作模式平顺地切换,依据切换前后驱动转矩相等的原则,提出一种新的电机转矩算法.该算法根据CVT的速比控制规律、车速、节气门开度得出发动机的伪目标转速；根据发动机输出特性、节气门开度和伪发动机转速,得出发动机输出转矩,由此推导出电机输出转矩.仿真结果表明:模式切换前后整车驱动转矩基... |

| Abstract: | This paper studied how to achieve hybrid electric vehicle's electric mode and engine mode switching smoothly.The main principle is the same driving torque.This paper proposed a new algorithm for the motor torque to achieve it.According to velocity and throttle and CVT's ratio,this algorithm obtains engine pseudo-target speed.According to engine output characteristics and throttle opening and engine speed,we got the engine output torque.And then we derived the motor output torque.Simulation results have show... |
| Keywords: | electric vehicle mode switching pseudo-target speed continuously variable transmission |
