To research the problem of abnormal bus data frame transmission, real-time signal voltage mutation value of BMW F18 K-CAN was measured by the IBIM synthetic testing box, and the cause of abnormal transmission on data bus was identified. Experiments compared and analyzed signal waveform of K-CAN under the conditions of data steady transmission, CAN-H to ground loaded with different resistance, CAN-H to battery loaded with different resistance, CAN-L to ground loaded with different resistance, CAN-L to batter...
Experimental Study on the Abnormal Transmission of Data Framesabnormal data transmission.1前言车身控制器区域网络(K-CAN)可有效实现车身区域内实时数据通信和控制信息共享[1-3],但在工作过程中由于各种原因造成数据总线传输异常,对电子组件造成危害[4]。因此,研究车身?
