On-Board Terminal Adjusts Roadside Sensing Data Using Baseline Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicular communication systems, the variability in sensing capabilities among different road side sensing devices leads to inconsistent accuracy of road side sensing data, which can result in unreliable processing results for on-board terminals.
Innovation Solution
A data processing method and apparatus where a road side communication device obtains baseline performance information of a road side sensing device, collects road side sensing data, and transmits both to an on-board terminal. The on-board terminal then adjusts the road side sensing data based on the baseline performance information to ensure accuracy.

1Productivity
If road side sensing data is directly forwarded to on board terminal without adjustment, then data transmission efficiency is improved, but processing accuracy deteriorates due to variability in sensing capabilities
Solution Approach 1:
The system performs preliminary action by obtaining baseline performance information about the road side sensing device before forwarding data to the on board terminal. This allows the on board terminal to pre-adjust its data processing parameters based on known sensing capabilities, ensuring accurate processing without requiring complex real-time adjustments or retransmissions.
2Measurement precision
If baseline performance information is obtained and transmitted to enable data adjustment, then processing accuracy is improved, but system complexity increases
Solution Approach 1:
The road side communication device serves as an intermediary that obtains baseline performance information about the road side sensing device and transmits this information to the on board terminal. This intermediary approach allows the system to maintain simple sensing and terminal devices while achieving accurate processing through the coordination provided by the communication device.
