外文文献翻译附录A(英文原文) Adaptive Clutch Engaging Process Control Automatic Mechanical Transmission LIU Hai’ou(刘海鸥),CHEN HUI’yan(陈慧岩),DING Hua’rong(丁华荣),HE Zhong’bo(何忠波) Abstract: Based on detail analysis of cluch engaging process control targets and adaptive demands,a control strategy which is based on speed signal,different from that of based on main clutch displacement signal,is put considers both jerk and slipping work which are the monly used quality evaluating indexes of vehicle starting adaptive control system and its reference model are discussed the adaptability to different starting gears and different road conditions as examples,some proving field test records are shown to illusrate the main clutch adaptive control strategy at starting field test gives acceptable results. Key words: automatic mechanical transmission(AMT); transmission technology; adaptive control; main clutch engagement The engaging process control strategy of friction main clutch,whether wet or dry,is the focus in vehicle technology of the control strategies are based on main clutch displacement adaptive control strategy has been developed, which is based on main clutch out put shaft speed signal grounded on our research is proved to have extensive adaptability. 1 Control Targets and Adaptive Demands The monly used quality eval
