摘要
为了改善电控机械式自动变速箱(automated mechanical transmission,AMT)自动换挡品质,文章针对电机-变速器一体化电驱动系统的控制特点,在分析无离合动力传动系统自动换挡原理的基础上,制定了自动换挡协调控制系统框架和实现流程,提出了一种基于驱动电机转矩、转速双闭环控制的自动换挡协调控制策略。设定综合工况下的仿真试验表明,系统自动换挡协调控制策略正确、可靠,换挡品质较好。
In order to improve the automatic shift quality of automated mechanical transmission (AM T ) ,in view of the control characteristic of motor‐transmission integrated drive system and based on the analysis of the au‐tomatic shift principle of the clutchless drivetrain ,the framework and implementation flow chart of coordina‐ted control system of automatic shift are made ,and a coordinated control strategy of automatic shift based on the torque and speed double closed‐loop control of driving motor is proposed .The results of the simulation under the settled conditions show that the coordinated control strategy of automatic shift is correct and relia‐ble ,and the shift quality is excellent .
