Bandwidth Analysis and Research of Automotive Video Transmission Module

With the rise of the driverless car technology and the popularity of ADAS, traditional CAN transmission network have been unable to meet the increasing demand, the on-board network transmission technology is the development trend of the high bandwidth, as the onboard Ethernet industrial chain mature, onboard Ethernet began to be used, but the onboard Ethernet technology is expensive, price is low. To help solve the problem, Chen Dian in vehicle-mounted LCD instrument sliding transmission system optimization and analysis of the feasibility of sliding technology in the data analysis [1], the scheme of the present study, scholars rarely sliding (Network Control Model) transmission technology, through to the virtualization of sliding devices into front-end ports, used for big data transmitted between device and host [2-3], proves that the sliding CAN be used to replace the onboard Ethernet data transmission, CAN be in a certain environment instead of the CAN Network for high bandwidth transmission, but its only studied the sliding work environment, The transmission between NCM and on-board Ethernet is not analyzed, so it is necessary to study it.
