Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If autonomous driving systems use basic navigation routes, then system complexity is reduced, but lane-keeping precision and driving safety deteriorate
Solution Approach 1:
The patent segments the route information into multiple hierarchical levels: basic navigation routes, detailed lane-level routes, and dynamic adjustment parameters. This segmentation allows the system to process only necessary detailed information for lane-keeping while maintaining overall system simplicity, resolving the contradiction between system complexity and lane-keeping precision.
Solution Approach 2:
The patent adds a temporal dimension to route information by providing dynamic updates and predictions about future road conditions, intersections, and traffic patterns. This enables the system to maintain high lane-keeping precision without requiring permanently complex system architecture, as complexity is activated only when needed.
2Measurement precision
If the system processes detailed map information in real-time, then lane-keeping accuracy improves, but computational time and processing load increase
Solution Approach 1:
The patent performs preliminary processing of map information offline to pre-calculate optimal routes, lane sequences, and intersection approaches. This pre-computation stores essential lane-keeping data in advance, allowing the real-time system to simply retrieve and execute pre-determined lane sequences without heavy computational processing, thus maintaining high accuracy while minimizing computational time.
Solution Approach 2:
The system applies different processing qualities to different spatial locations: high-detail processing for current and near-future segments where lane-keeping is critical, and lower-detail processing for distant segments. This local quality differentiation maintains lane-keeping accuracy in critical zones while reducing overall computational time and processing load.
3Device complexity
If the vehicle uses fixed lane-keeping strategies, then control system simplicity is maintained, but adaptability to dynamic road conditions deteriorates
Solution Approach 1:
The patent implements dynamic lane-keeping strategies that automatically adjust based on real-time road conditions, detected objects, and navigation context. The system transitions between different control modes (e.g., aggressive lane-centering, conservative lane-following, intersection preparation) based on situational parameters, maintaining control system conceptual simplicity while achieving high adaptability through rule-based dynamic adjustment.
