中国汽车控制单元的设计与研究 摘要 随着社会的发展，人类对汽车的性能和环保提出了更高的要求。传统的机械装置已经无法解决某些与汽车功能要求有关的问题， 因而将逐步被电子技术和汽车融为一体的现代汽车电子控制技术所取代。电子控制技术正被广泛地应用在汽车的各个方面，它不仅能提高汽车的动力性、经济性和安全性，改善行驶的稳定性和舒适性，推动汽车工业的发展，还为电子产品开拓了广阔的市场。 设计针对当前我国汽车喷油控制、电动天窗控制、防盗控制、自动转向灯控制及车门自动锁控制技术的现状及实现电控化和降低排放污染物的首要任务，通过对国内外汽车电控技术、喷油控制、电动天窗控制、防盗控制、自动转向灯控制及车门自动锁控制系统发展的相关资料进行分析，结合实际状况，系统采用多传感器信息融合的方式，通过进气歧管绝对压力传感器(MAP)、转速及曲轴位置传感器(CPS)、冷却液温度传感器(CTS)、进气温度传感器(IAT)、节气门位置传感器(TPS)、氧量传感器、红外线传感器、判缸信号传感器、角度传感器、天窗开关、起动信号等发出的各种状态信号，电控制单元对采集到的信号进行筛选、处理之后，驱动执行机构，实现对燃油喷射、天窗、防盗、转向灯、车门锁的控制。并且软件设计包括各工况喷油程序设计、自动转向灯、车门自动锁、防盗及电动天窗等程序设计。 关键词：电控单元，燃油喷射，电动天窗，防盗，自动转向灯，车门自动锁 The design and research of automobile control unit ABSTRACT With the development of the society, human and environmental protection on the performance of the car put forward higher request. Traditional mechanical devices have been unable to solve some problems associated with cars function requirements, and will gradually be electronic technology and automotive integrated modern automotive electronic control technology. Electronic control technology is being widely used in all aspects of the car, it can not only improve the car power, economy and security, improve driving stability and comfort, to promote the development of automobile industry, also develop a broader market for electronic products. Design in view of the current our country automobile fuel injection control, automatic control, security control, electric sunroof turn signal control and automatic door lock control technology present situation and implementation of electronic control and reduce the discharge of pollutants of priority, based on automobile electronic control technology at home and abroad, the fuel injection control, electric sunroof control, security control, automatically turn signal control and data about the development of the automatic door lock control system is analyzed, combined with the actual situation, the system with the method of multi-sensor information fusion, t
