Analysis and Solution of Electromagnetic Immunity of Vehicle CAN_FD Bus
In this paper,Based on the three-element theory of EMC,the mechanism of error frame in PT_CAN system during radiation immunity test of a test vehicle is studied,and the improvement measures were put forward in the system harness layout and the controller design.At the same time,the effectiveness of the rectification scheme is proved according to the test of the vehicle verification.Finally,the design optimization thinking and suggestions are given from the aspect of system architecture design.
