1.purpose and significance (including analysis of researchstatus at home and abroad)

since 1939, the united states buick motorcompany first used the zhuangyong hydraulic transmission on the oldsmobilesedan, and gradually appeared a hydraulic transmission that automaticallycontrolled the gear shift based on the engine operating signal. french renaultauto company first applied electronic components to automatic transmissions inthe late 1960s, and japanese auto companies have subsequently adopted thistechnology. in 1982, toyota motor corporation adopted the electronic controlunit technology in its electronically controlled transmission system to achievethe rapid development of electronically controlled transmission systems. theelectronically controlled automatic transmission matches the outputcharacteristics of the engine and has been widely used in passenger cars andcommercial vehicles.

as manual transmissions cannot meet people'sneeds for vehicle driving in recent years, various companies have begun todevelop automatic transmissions. in 2008, li shufu ^[1] lectra agreedto acquire dsi, and cooperated in various aspects while mass production.continuous innovation and development made china take care of the situationthat the automatic transmission is subject to people.
