【摘要】：随着汽车行业的发展,汽车电子在汽车中的作用越来越重要。尤其是汽车ECU,协调汽车各部分工作,如同汽车的"大脑",在汽车安全稳定行驶以及汽车的舒适性方面具有极其重要的作用。现阶段,国内外越来越多的厂商和高校在汽车ECU研发上投入大量的资源,希望能够研制出高性能汽车ECU,促进国内汽车产业的发展。不同类型的汽车所使用的汽车ECU有着自己的特点,但具有一定的共性,差别主要体现在功能的侧重点不同。针对这些共性,可以设计出一种适用于不同车辆的汽车ECU,即通用的汽车ECU。本文通过分析传统ECU的设计要点和功能需求,采用模块化设计方法,提出了一种通用汽车ECU的实现方案,通过对所设计的汽车ECU进行相关配置即可用于不同类型车辆。本文着重实现汽车ECU的各种基本功能,具体的汽车控制方案由其他研发人员提供。汽车控制方案实现人员在设计自己的汽车ECU时,只需要提供控制方案,设置相关参数即可。本文从硬件和软件角度,以及分别从数据输入输出模块、通信模块、数据存储模块和故障诊断等方面介绍了通用汽车ECU的实现方案。在设计时着重强调了其通用性。在硬件方面设计时突出了其可配置性;在软件方面,通过移植德国3S公司的CoDeSys,在嵌入式平台上实现了软PLC,利用嵌入式软PLC这个开放软件平台,极大方便各种汽车控制方案的实现。另外,本系统通过简洁的电路,可以实现在线故障检测,一旦出现故障可以及时发现并执行相应故障处理措施。
[Abstract]:With the development of the automotive industry, automotive electronics becomes more and more important in the car. Especially the car ECU, coordinate parts of a car, the car as the "brain" plays an important role in the comfort of the vehicle safety and stable running of the car. At this stage, invest a lot of resources in the research and development of ECU car more and more domestic and foreign manufacturers and universities, hope to be able to develop high performance automotive ECU, promote the development of the domestic automobile industry. By using different types of cars ECU has its own characteristics, but has certain similarities, the difference is mainly reflected in the functions of the different focus. According to these characteristics, we can design a applicable to different vehicle ECU, namely the general automobile ECU. through the analysis of the demand and function of traditional ECU design, using modular design method, put forward a kind of General Motors ECU Through the implementation of the design can be configured for different types of vehicles ECU automobile. This paper focuses on the implementation of all the basic functions of car ECU, car specific control schemes provided by other researchers. Auto control personnel in the design of their own car ECU, only need to provide the control scheme, set the relevant parameters. This paper from the angles of hardware and software, and the output module are respectively input from the data communication module, data storage module and fault diagnosis method was introduced. The ECU of General Motors in the design emphasizes its versatility. In the aspect of hardware design is highlighting its configuration; in the aspect of software, through the transplant of Germany 3S CoDeSys, in the embedded platform to realize the soft PLC, the use of embedded soft PLC the open software platform, realizes the convenient auto control scheme. In addition, the system can realize on-line fault detection through a simple circuit. Once the fault occurs, it can detect and execute the corresponding fault treatment measures in time.
