1数据流的定义汽车控制系统的数据流是反映控制单元、传感器、执行器的工作状态。以及控制单元与传感器、执行器之间传输的当前数据信息。控制单元根据输入信息确定系统当前的状态,数据流是实时刷新的。这些数据信息沿时间轴在传感器、控制单元、执行器间作有序持续地流动,数据流就是这些有序持续地流动的数据信息序列。2获取数据流的不同方法及方法的优劣对比用故障检测仪与控制单元之间建立通信,从控制单元
1 data flow definition Automotive control system data flow is to reflect the control unit, sensors, actuators work status. As well as the current data information transmitted between the control unit and the sensors and actuators. The control unit determines the current state of the system based on the input information, and the data flow is refreshed in real time. These data messages flow continuously and orderly along the time axis between sensors, control units and actuators, and the data stream is the sequence of these data messages flowing in an orderly manner. 2 access to different data streams and methods of comparison of pros and cons Fault detector with the control unit to establish communication between the control unit
