Research And Development On Center Controller And Car Door Control System Of Electromotion Vehicle Based On CAN Bus

With the rapid development of the modern electronic information technologyand the enhancing of the level of car building in our country, the automotiveelectronic technology which has been integrated with the modern automotivetechnologies, electronic and information technologies is also in progress.The thesis lays emphases on the research and development on center controllerand car door control system of electromotion vehicle based on CAN bus.Firstly, the development course and the structure and the hardware andsoftware designs and realizations of the center controller and the car door controlsystem are depicted generally. Then, the article detailedly discusses the designingprogress of their hardware and software. What's more, it describes the hardwarestructures of every module and the software design flows of each control system.These ensure that the center controller could manage the dynamic system and othervehicle subsystems of an electromotion automobile effectively. At the same time,through analyzing and testing the car window motors'structures, it brings forwardthe solution of car window anti-nip.Secondly, it depicts the principles of CAN bus and the system bus structures ofthe whole system. Referring to SAE J1939, it constitutes the protocols among thecenter controller, the car door control system and other control system.In conclusion, the research in aspects of actual applications introduces thecenter controller and the car control system roundly, which sets up a stable base forfuture automotive electronic control systems'developments.
