Research on physical signal evaluating of new energy Bus CAN network

Based on the new energy vehicle CAN bus network physical signal quality and testing of the network error frames, analysis of SAEJ1939 and ISO11898 standards, VCU physical signals are measured and network communications quality under different physical signals is compared through HIL platform simulating vehicle communications. The test results show that under the same conditions to build a network, the different physical signal level parameters will result in a big difference of the communication quality of the bus.
