Vehicle Sensor Data Sharing via Common Region Downsample
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face inefficiencies in sharing sensor data, leading to unnecessary bandwidth consumption and processing time due to the transfer and processing of redundant data.
Innovation Solution
A method and system for sensor data sharing between vehicles, where an ego vehicle and other vehicles determine common regions of sensor coverage, downsample and compress redundant data, and transmit only the necessary data to enhance each other's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all sensor data is transmitted between vehicles, then complete environmental information is shared, but bandwidth consumption and processing time increase significantly
Solution Approach 1:
The patent extracts only the essential and non-redundant sensor data for transmission. By identifying common regions of sensor coverage between vehicles and determining which data is already available at the receiving end, the system transmits only the necessary portions of sensor data, eliminating redundant information transfer while preserving complete environmental information where needed.
2Measurement precision
If high resolution sensor data is transmitted, then data quality is maintained, but transmission bandwidth and processing requirements increase
Solution Approach 1:
The patent applies different quality levels to different portions of sensor data based on their importance and redundancy. In common regions of sensor coverage, lower resolution data is transmitted since the receiving vehicle already has similar data. In non-common regions, higher resolution data is transmitted to maintain measurement precision where it is most needed, optimizing the balance between data quality and transmission volume.

AI summary
Two vehicles—an ego vehicle and an other vehicle—can share sensor data in a streamlined manner. One or more sensors can be configured to acquire first environment data of an external environment of the ego vehicle. A data summary based on second environment data of an external environment of the other vehicle can be received. Whether there is a common region of sensor coverage between the ego vehicle and the other vehicle can be determined. In response to there being a common region, the first environment data that is located within the common region can be identified and the resolution level of the identified first environment data can be reduced. The first environment data that has the reduced resolution level and a remainder of the first environment data excluding the identified first environment data can be transmitted to the other vehicle.
