1、 1 数据流分析在电控发动机故障诊断中的应用数据流分析在电控发动机故障诊断中的应用 摘要：汽车电子化发展迅速，应用之广泛与日俱增，尤其是微机、网络、计算机技术 的发展为汽车电子化带来了根本性的变革。当代汽车维修不单纯是机械维修，而汽车电子 控制元件的维修比较抽象，给汽车维修技术带来了新的挑战。随着车载诊断系统（OBD-I OBDII）的普遍采用汽车示波器和汽车诊断仪的诞生,为汽车维修人员快速判断汽车电子系 统故障提供了有力的工具。电子设备的测试变得简单，易操作，无需任何设定和调整就可 以直观观察电子元件的信号波形和读取数据流。这就为广大维修人员分析汽车各个传感 器、执行器的信号波形和数据流分析

2、提供了方便。 关键词： 汽车电子控制技术 数据流分析 波形分析 OBD-I OBD-II 传感器 Abstract: The rapid development of automotive electronics, growing a wide range of applications, especially computer, network, development of computer technology has brought fundamental changes to the automotive electronics. Contemporary vehicle maint

3、enance is not simply a mechanical maintenance, and maintenance of automotive electronic control components is quite abstract, vehicle maintenance technology has brought new challenges. Board diagnostic systems (OBD-I OBDII) commonly used by the birth of the automotive oscilloscope and automotive dia

4、gnostic equipment, automotive electronic systems for vehicle maintenance personnel quickly determine failure to provide a powerful tool. Testing of electronic equipment is simple, easy to operate, without any of the settings and adjustments can directly observe the electronic components of the signal waveform and read data stream. This analysis of automotive sensor and actuator signal waveforms and data flow analysis provides a convenient for the majority of maintenance personnel. Keywords: da
