摘要
自动离合器取消了离合踏板,采用电控驱动装置实现自动离合。针对自动离合器接合过程中要实现平稳接合与快速分离的问题,采用无刷直流电机来驱动离合器执行机构。介绍了用于驱动离合器执行机构的无刷直流电机调速系统,系统以ATmega16为核心实现快速控制,以脉冲宽度调制(PWM)调速技术实现了稳定调速,用ZLG7290芯片实现了各数据的显示。研究结果表明,与常规调速系统相比,该调速系统具有调速范围宽、动态响应性能良好和系统稳定等优点,能够满足自动离合器自动控制的要求。
Automatic clutch＇s clutch pedal is unfixed and electronic control device is put to use in automatic clutch.Aiming at the problem of stable engaging and fast release in the process of Automatic clutch＇s engaging,a brushless DC motor was picked to drive the clutch＇s actuator.A brushless DC motor speed control system which used to drive the automatic clutch＇s actuator was introduced,using ATmega16 for the purpose of fast control,the pulse width modulation（PWM） was used to realize stable speed regulation and ZLG7290 was used to show some kinds of data.The results indicate that,compared with other speed control systems,this system owns its advantages,such as wide speed range,nice dynamic response property,good stability and so on.Furthermore,it can satisfy the request of automatic clutch.
