Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicle data labeling, and particularly relates to a vehicle networking direct connection communication test vehicle data labeling method and system. BACKGROUND

[0002] At present, the vehicle networking direct connection communication function designed and developed at home and abroad based on V2X direct connection communication technology (DSRC, LTE-V2X R14, R15, 5G NR V2X) mainly realizes information sharing in a short-distance broadcast mode, for example, the cooperative intelligent transportation system defined in the domestic standard GB / T31024, a vehicle and a roadside device periodically broadcast relevant information (such as the current latitude and longitude, speed, gear position, brake state, steering light state, double flash state, etc.) to the outside, and do not pay attention to the current number of information receivers and how to use the information.

[0003] In the short-term interaction scene in the V2X application process, other vehicles and roadside devices need to track the continuous state of the vehicle for a period of time, because the vehicle needs to include an ID (such as the vehicle ID in the BSM of the vehicle broadcast information defined in the GB / T 31024 standard) in the broadcast information to the outside world, but at the same time, the vehicle broadcast information to the outside world includes the current position of the vehicle, the historical trajectory of the vehicle and other related information designed for safety and privacy. In order to prevent illegal behaviors such as vehicle tracking by using V2X messages, the ID in the vehicle broadcast message to the outside world will be randomly updated and produced at irregular intervals to prevent the vehicle from being locked by other receivers. This makes it impossible to distinguish which data packets come from the relevant measured vehicle of interest when using a vehicle networking wireless signal receiving device to test the vehicle broadcast data in an open external field. Therefore, the present application provides a vehicle networking direct connection communication test vehicle data labeling method and system. SUMMARY
