Automated driving data return requirements

1. Demand analysis

user	User needs	real-time requirements	Need to return data	type of data	The sampling period	The amount of data size	data return channel
R & D Engineer	Analyze and evaluate system performance, such as smart driving mileage statistics, takeover rate performance, fuel consumption performance, AEB alarm times, etc.	the day	Body chassis data, automatic driving system status data, etc.	structured data	100ms class	Small	4G/5G
	Process and analyze the cause of the problem, and the original data is used for AI model training, simulation restoration and algorithm iterative development	≤ 3 days	Obtain full perception raw data, intermediate data of the automatic driving system, and vehicle body and chassis data before and after the problem moment or before and after the test engineer manages,	structured data + unstructured data	10ms~100ms level	very big	Move the hard disk to the service provider node for copying
Port customers	Safety Supervision: Supervise vehicles, realize a series of process-related management functions such as port freight vehicle supervision, alarm, maintenance, and cooperate with the dispatching department to jointly complete emergency fault handling	real time	Data such as running status, job status, vehicle status, safety warning, abnormality, etc. + video data around the vehicle	structured data + unstructured data	10ms~100ms level	middle	Port 5G Intranet _
	Digital twin: 2D and 3D data view multi-dimensional presentation, real-time reconstruction of high-precision 3D scenes. It can display the real-time operating status of the port, as well as information such as the operating status, location, speed, power, remaining mileage, and gear of the vehicle. At the same time, it can obtain information such as the current task ID, destination, and task progress of the vehicle .	real time	Vehicle running status, location, speed, power, remaining mileage, gear and other information	structured data	100ms class	Small	Port 5G Intranet _
Logistics operation platform	The fleet platform monitors the location and status of vehicles in real time	real time	Vehicle position, speed, license plate number, ignition status, automatic driving status, etc.	structured data	100ms class	Small	4G/5G
	When a risk event occurs to a vehicle, the fleet management platform can view the environment and driver data when the risk occurs	≤1min	AEB/LDW/DMS risk events, vehicle peripheral video data, driver video data	structured data + unstructured data	50ms level	middle	4G/5G
