摘要
文中根据发动机与液力变矩器联合工作特性,制定了两参数换档规律,同时为了提高液力变矩器的工作效率又对换档规律进行了修正,然后依据换档规律建立了整车动力系统仿真模型,并对模型进行了离线仿真分析,验证了自动变速器控制系统模型的正确性。
According to the joint work characteristics of engine and torque converter,two-parameter shift schedule is built,and in order to improve the efficiency of the torque converter,the shift schedule has been amended.Then a vehicle power system simulation model is established and off-line simulation is carried out according to shift schedule,the results verified that the automatic transmission control system model is correct.
