摘　　要：为了提升电控汽车在换挡过程中的顺畅度及舒适性,实现自动变速的换挡控制功能,分析了换挡质量的衡量指标,构建车辆传动系统中核心部件发动机、离合器、变速器的动力学模型以及车辆阻力模型,详细设计了自动变速换挡控制系统的转速控制模块、变速执行模块以及动态抗扰动模块。利用PID控制实现发动机的转速调整,利用选换挡电机实现变速控制,采用动态滑膜算法提升系统抗扰动能力。经过实车验证,系统在升档过程中换挡耗时1.15 s,车辆冲击度在4 m/s3以内,耗时短、冲击小,达到了良好的换挡控制效果。In order to improve the smoothness and comfort of the electronically controlled vehicle in the process of shifting,realize the shift control function of automatic transmission,measurement indexes of shifting quality are analyzed,and the dynamics model of the engine,clutch and transmission,the core components of the vehicle transmission system,and the vehicle resistance model are constructed.The speed control module,speed shifting executive module and dynamic anti-disturbance module of the automatic speed shifting control system are designed in detail.The speed adjustment of the engine is realized by using PID control,the speed control is realized by using the gear-selecting and shifting motor,and the anti-disturbance ability of the system is improved by using dynamic synovial membrane algorithm.After actual vehicle verification,the system takes 1.15 s to shift in the process of shift up,and the vehicle impact degree is within 4 m/s 3,which is short in time and small in impact,and achieves good shift control effect.
