Abstract: Aiming at the problem that the current EDR standard and equipment cannot meet the requirement of multiple items and large amount of data for autopilot vehicle data recording,the autopilot vehicle data recording and uploading system was designed.Through the development of special ADR equipment and the transformation of many existing equipment modules of the vehicle, the system had completed the design of the vehicle network connection terminal, video recording equipment and cloud data management platform of the ADR equipment. It could collect and record the data from monitoring video, perception, decision-making and control information of the autopilot vehicle, and realized the Ethernet communication between the devices in each domain through the two-wire Ethernet gateway.The practical application results showed that the system could collect and record more and more comprehensive autopilot vehicle event data,and could easily and quickly extract data,which not only provided effective data support for accident liability determination, but also provided the necessary data source for the verification and evaluation of autonomous vehicles so as to promotes the rapid iterative upgrade of autopilot system.
