发动机负扭矩工况下的DCT传动系统换挡控制策略
Control Strategy of DCT Shift Based on Engine with Negative Torque
摘要
Abstract
For the particular engine conditions of negative torque when automobiles were in the downhill,or slowing down,or overtaking,etc,this paper established a system dynamics model of the shift process of DCT power drive system with the experimental data of the negative torque condition of engine.According to characteristics of the torque with the rotating speed when the engine provides negative torque,this paper put forward a kind of control strategy of DCT shift.Through the corre-sponding simulation analysis,results show that the control strategy is feasible.关键词
