Research On Time-domain Analysis Method Of Vehicular Communication Buses

The time-domain transient analysis is the research hotspot of transmission lines inrecent years. in this paper， the time-domain analysis of generalized buses in vehiclecommunication system are studied.Based on the analysis of vehicle communication system generalized buses, it isfocused on the transmission characteristics and coupling leak mechanism of data buses.Based on the transmission line equations, the theory derivations of lossness and lossytransmission lines are finished, with the solution equations. Using the accuratecalculation method of transmission line, with twisted pair as an example, the calculationmodel of non-uniform transmission line is proposed. By comparison with the referencesliterature, the method is verified to be correct. the time domain analysis program oftypical data buses is compiled, which complete the "Vehicular communication systembuses EMC Simulation Software Version1.0" software. Finally, the comparisoncalculation of pratical buses layout is finished, with some conclusions got, which willprovide theoretical guidance for the purpose of system wiring.
