摘　　要：车载传感器的标定关系到汽车驾驶的舒适性和安全性,标定过程中需要对汽车ECU系统的总线协议进行检测。传统的硬件电路检测速度较快但检测范围受到限制,而完全软件检测速度较低。为了完成车载传感器的标定,设计了一种用于汽车传感器标定的ECU总线检测方法,检测方法采用软件和硬件相结合的方式,克服了软件或硬件检测的缺点。经测试该检测方法反应速度快,应用范围广。The calibration of on-board sensors is related to the comfort and safety of vehicle driving. In the process of calibration, the bus protocol of vehicle ECU system needs to be detected. The traditional hardware circuit has quick detection speed, but limited detection range. The software detection has wide range, but low detection speed. In order to complete the calibration of vehicle sensors, this paper designs an ECU bus detection method for vehicle sensor calibration. The detection method combines software and hardware to overcome the shortcomings of software or hardware detection. The test results show that the detection method has fast reaction speed and wide application range.
