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 fort, 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, bined with the actual situation, the system with the method of multisensor information fusion, through the intake manifold absolute pressure (MAP), rotational speed sensor and crankshaft position sensor 摘要 化工學(xué)院化工機(jī)械系 III (CPS), the coolant temperature sensor (CTS), the inlet temperature sensor (IAT), throttle position sensor (TPS), oxygen sensor, infrared sensor, cylinder signal sensor and Angle sensor, skylight, start signal and other signal the various states, the electric control unit of the collected signal after filtering, processing, drive actuators, implementation of fuel injection, skylight, antitheft, turn signal, the control of car door locks. And the software design including the design of working condition of the fuel injection process, automatically turn signal, automatic door locks, antitheft, electric sunroof program design, etc. Key words: electronic control unit, fuel injection, electric sunroof, guard against theft, automatic lights, the door automatically locks 目錄 化工學(xué)院化工機(jī)械系 V 目錄 .............................................................................. 1 課題的研究背景和意義 ........................................................... 1 國內(nèi)外研究發(fā)展現(xiàn)狀 ............................................................. 1 ............................................................ 2 設(shè)計(jì)背景描述 ................................................................... 2 設(shè)計(jì)方案 ....................................................................... 2 .......................................................... 4 微處理器介紹 ................................................................... 4 內(nèi)容分析 ................................................................... 5 芯片引腳介紹 ............................................................... 6 EPROM .................................................................... 8 RAM ....................................................................... 8 主電路設(shè)計(jì) ..................................................................... 8 時鐘電路 .................................................................. 8 復(fù)位電路 ................................................................... 9 存儲器電路 ................................................................. 9 ECU 控制設(shè)計(jì) .................................................................. 10 執(zhí)行機(jī)構(gòu)的設(shè)計(jì) ............................................................ 10 噴油量的控制系統(tǒng)噴油器 的設(shè)計(jì) ............................................. 10 點(diǎn)火驅(qū)動電路的設(shè)計(jì) ........................................................ 12 電動天窗電機(jī)驅(qū)動電路的設(shè)計(jì) ............................................... 12 報(bào)警電路的設(shè)計(jì) ........................................................... 12 轉(zhuǎn)向燈指示電路的設(shè)計(jì) ..................................................... 13 車門自動鎖驅(qū)動電路 ....................................................... 13 ................................................................. 15 需檢測的參數(shù)測量方式設(shè)計(jì) ...................................................... 15 汽車曲軸轉(zhuǎn)速的測量設(shè)計(jì) .................................................. 15 冷卻液溫度的測量設(shè)計(jì) ..................................................... 15 進(jìn)氣溫度的測量設(shè)計(jì) ....................................................... 16 進(jìn)氣壓力的測量設(shè)計(jì) ........................................................ 16 節(jié)氣門開度的測量設(shè)計(jì) ...................................................... 17 1 緒論 VI 化工學(xué)院化工機(jī)械系 廢氣中含氧量的測量設(shè)計(jì) .................................................... 18 判缸信號的測量設(shè)計(jì) ........................................................ 18 起動信號的檢測設(shè)計(jì) ........................................................ 19 跟蹤人體目標(biāo)信號的檢測電路 ............................................... 19 方向盤轉(zhuǎn)角信號的檢測電路 ................................................. 20 車門開關(guān)檢測電路的設(shè)計(jì) ................................................... 20 天窗開關(guān)量輸入電路 ....................................................... 21 .......................................................................... 22 概述 .......................................................................... 22 軟件設(shè)計(jì)策略 .................................................................. 22 程序資源分配 .............................................................. 22 軟件設(shè)計(jì)方法 ...................................
