Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication data streams are fused to reduce communication load, then communication efficiency is improved, but error detection and defense capability deteriorates
Solution Approach 1:
The patent segments the communication data stream into multiple parallel data streams, each with its own verification data chain containing check bits. This segmentation allows error detection for each individual stream while maintaining overall communication efficiency through parallel processing.
Solution Approach 2:
The patent introduces verification data chains with check bits as intermediary elements between the fused communication data streams. These check bits act as mediators that enable error detection without significantly increasing the communication load, as they are integrated into the existing data structure.
2Reliability
If verification data chain with multiple check bits is created, then error detection capability is improved, but data processing complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-calculating and attaching verification data chains with check bits to the communication data before transmission. This preliminary verification setup simplifies the receiving end processing, as error detection can be performed through straightforward check bit validation rather than complex real-time analysis.
Solution Approach 2:
The verification data chain structure is designed to be self-verifying through its check bits. The system automatically detects errors without requiring external intervention or complex processing algorithms, as the check bits inherently contain the necessary information for error detection when properly configured.

AI summary
The disclosure solves a problem of a poor ability in controlling and defending against a data error risk of a vehicle driving assistance system during data communication. The data processing method includes: creating a verification data chain for verifying vehicle-carried data of a target vehicle, where the verification data chain includes a plurality of check bits; and handling a communication error when the communication error is detected in the vehicle-carried data of the target vehicle based on the verification data chain. In the present application, when a data transmission process is subjected to interference or malicious attacks, it is possible to detect a communication error in communication data by the check bits and record the communication error, thereby achieving a purpose of controlling and defensing against data error risks.
