摘　　要：为了提高汽车变速的连贯性和稳定性,提出基于扭转减振的汽车机械式自动变速系统设计方法。由主控制芯片、最小系统、输入/输出电路、通信接口、电机驱动电路和扭转减振器构成汽车机械式自动变速系统的硬件结构。建立了汽车起步状态和滑挡状态下的动力学模型,在此基础上分别通过模糊控制和Fuzzy-Bang Bang双模式控制实现汽车的变速控制,完成汽车机械式自动变速系统的设计。实验结果表明,本文方法的换挡时间短,换挡过程的稳定性高。In order to improve the consistency and stability of automobile transmission,a design method of automobile mechanical automatic transmission system based on torsional damping is proposed.The hardware structure of automatic mechanical transmission system is composed of main control chip,minimum system,input/output circuit,communication interface,motor drive circuit and torsional damper.The dynamic model of the vehicle in the starting state and the sliding state is established.On this basis,the vehicle speed control is realized through fuzzy control and Fuzzy-Bang Bang dual mode control,and the design of the automatic mechanical transmission system of the vehicle is completed.The experimental results show that the shift time of the proposed method is short and the stability of the shift process is high.
