Abstract: In recent years, with the development of electronic technology, a variety of novel electrical and electronic functions begin to be applied on the vehicle, electrification, intelligence, gesture recognition, face recognition and other functions gradually become a new choice for consumers, the kick function of power tailgate is one of the major representatives. The article mainly studies the design of the kick function of power lift gate system, the article starts from the induction principle of capacitive kick, and combines the development experience of the real car kick in the work, and discusses the network architecture and layout requirements of the kick system. At the same time, in order to meet the static power consumption requirements of the whole vehicle, combined with the working characteristics of the local interconnect network (LIN) bus, the sleep wake-up strategy and functional logic are required in detail, and the vehicle equipped with the kicking system has high testing kick sensitivity, reasonable functional logic design, and low static current consumption, which has certain reference significance for the design of the kick function of subsequent models.
