Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle uses external map information from the server and internal information from electric components, then the map data can be updated and enriched, but inconsistency between external and internal information may cause erroneous data and system failures
Solution Approach 1:
The patent introduces a map providing device as an intermediary component between the server and electric components. This device receives both external map information from the server and internal information from electric components, processes them through reliability assessment, and provides validated information to the electric components. The intermediary structure isolates the complexity of multi-source information integration from the electric components while maintaining reliability through centralized validation.
Solution Approach 2:
The patent implements a feedback mechanism where the map providing device assesses the reliability of incoming map information from both the server and electric components, compares consistency between sources, and uses this feedback to determine whether to update the processed map. The system continuously monitors information quality and adjusts map updates based on reliability assessments, creating a closed-loop information management system that prevents erroneous data propagation.
2Reliability
If the vehicle processes and validates all incoming map information to ensure consistency, then data reliability improves, but computational load increases
Solution Approach 1:
The patent applies partial action by implementing selective reliability assessment rather than validating every piece of information equally. The map providing device assesses reliability based on the type of information, the source credibility, and the consistency requirements. For routine or highly reliable information sources, the system performs minimal validation, while for critical or uncertain information, more thorough assessment is conducted. This partial validation approach maintains necessary accuracy while reducing unnecessary computational overhead.
3Productivity
If the system updates map data frequently to maintain up-to-date information, then the usefulness of autonomous driving improves, but the risk of using erroneous or inconsistent information increases
Solution Approach 1:
The patent implements preliminary action by performing reliability assessment and consistency checking on map information before it is updated into the processed map. The map providing device evaluates incoming information from the server and electric components, validates its reliability, and only incorporates it after successful verification. This pre-validation approach ensures that updates maintain consistency and accuracy while still achieving timely map data refreshes, preventing erroneous information from compromising system reliability.
