【摘要】：随着汽车行车安全的要求不断提高,安全气囊系统已经成为汽车的标准配置,可以在发生碰撞的过程中有效减少伤害,作为安全气囊的核心部分ECU(电子控制系统),在出厂之前必须经过大量的测试来实现数据的采集、分析,以满足灵敏度和反应性的问题。但由于采取实际碰撞的收集方式成本很高,每次都会造成大量的机械成本投入,因此亟待一种可以避免实际碰撞的低成本、可充分形式加以改进,这也是本论文所研究的重点内容。总体上论文研究包括三个部分,第一部分是选题综述研究,利用文献研究法收集与论文相关的文献资料,了解相关的技术内容,如以太网通讯模块、CAN技术等;第二部分是碰撞传感器模拟系统进行总体设计,采取了文献研究法、实证研究法、对比研究法,本论文中的设计是基于插卡式设计,这一技术在目前国内的实验室研究中已经相对成熟。第三部分是系统的实现与测试,具体展开测试的过程中,主要采取的实证研究法,测试设计包括按照需要启动不同数量的板卡、在板卡之间通过CAN通讯等,并通过与整个系统的通讯通过工业以太网与计算机连接,打造一个符合实际需求的测试开发虚拟环境。通过阶段性验证以及最终系统测试结果表明,该系统基本可以实现汽车碰撞传感器模拟系统的要求,在汽车安全气囊触发方面有较好的灵敏性。
[Abstract]:With the increasing requirements of vehicle driving safety, airbag system has become the standard configuration of the vehicle, which can effectively reduce the damage in the process of collision. As the core part of the airbag, ECU (Electronic Control system) has to go through a lot of tests to realize the data collection and analysis before leaving the factory to satisfy the problems of sensitivity and reactivity. However, because of the high cost of collecting the actual collision, each time will result in a large amount of mechanical cost input, so there is an urgent need for a low cost that can avoid the actual collision and can be improved in a sufficient form. This is also the focus of this paper. As a whole, the thesis includes three parts. The first part is the research of topic selection, using the method of literature research to collect the relevant documents, to understand the relevant technical content, such as Ethernet communication module can technology; The second part is the overall design of the collision sensor simulation system, which adopts the literature research method, the empirical research method, the contrast research method. The design in this paper is based on the card design. This technology has been relatively mature in laboratory research in China. The third part is the realization and test of the system. In the process of the test, the paper mainly adopts the empirical research method. The test design includes starting the different number of boards according to the need, communicating between the boards through CAN, and so on. And through the communication with the whole system through the industrial Ethernet and computer connection to create a test and development of virtual environment in line with the actual requirements. The results of stage verification and final system test show that the system can basically meet the requirements of vehicle collision sensor simulation system and has good sensitivity in triggering automobile airbag.
