【摘要】 随着国际化排放法规的加严，在国际上兴起了以发动机电子控制为核心的汽车电控高科技，这一技术使汽油机在动力性、经济性、排放性等方面均取得了很大的进步，是唯一能够适应现代社会对汽车各种使用要求的技术。本文主要内容就是在借鉴国内外先进电控技术的基础上对汽油机电控单元硬件和软件开发技术进行分析和设计。 汽油机电子控制的关键技术是汽油机电子控制单元(ECU)的软件、硬件的开发，通过对其硬件电路和软件程序的不断改进，逐步满足汽车电子各方面更加精确控制的要求。我们结合我国当前排放法规的要求和燃油品质的现状，分析了汽油机电控技术和465Q发动机的具体情况，主要以INTEL的80C196KB单片机为主芯片，设计了喷油控制系统的软件和硬件，利用PROTEL电路设计软件绘制了硬件电路图和INTEL汇编语言设计了包括喷油主程序、脉宽计算程序、A/D转换程序和转速计算程序在内的汇编软件。 该系统经运行调试后，基本可以实现发动机的喷油要求，为以后设计用于发动机电控单元(ECU)的控制提供了一定的参考。更多还原

【Abstract】 As the vehicle emission regulation becomes stricter, the vehicle electronic control technology as the key of engine control has changed more and more popular in the world. This key technology is the unique technology fitting for the require of the using of vehicle in the model society for it had made a good progress in the power, economic, emission etc.. This paper is to research and design the hardware and software of ECU based on the referrence of foreign advanced ECU technology.The key of the engine electronic control is to develop the hardware and software of ECU. The need of more accutive control for the vehicle electronics is satisfied gradually through the gradual development of the hardware and software.Combined with the request of current emission regulation and fuel qualify, we analysis the ECU technology and the real environment of 465Q engine, then designed the hardware and software of the fuel injection of the ECU with the 80C196KB of INTEL as the main CMOS chip. Drawed the hardware circuit with the PROTEL software and designed the ASM software proceeding etc..Hardware and software tests show that the improved ECU can meet the basic requires of the vehicle. At the same time, gave out the reference for the design of the best ECU in the future.更多还原
