Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If multiple driver assistance systems are integrated into one system, then high-level autonomous driving capability is improved, but system complexity increases
Solution Approach 1:
The integrated control system is segmented into multiple independent control modules, each responsible for specific driver assistance functions. This modular architecture allows high-level autonomous driving capability to be achieved through integration of specialized modules while managing complexity through clear functional boundaries and independent operation of each segment.
2Reliability
If control commands from multiple systems are integrated and mediated, then control performance is improved, but processing time increases
Solution Approach 1:
Control commands from multiple driver assistance systems are pre-processed and prioritized before final integration. The system performs preliminary mediation by assigning priorities to commands based on safety criteria, so that when commands are integrated, the highest priority commands are executed first, minimizing processing time while maintaining control performance.
3Reliability
If priority-based mediation of control commands is implemented, then driving safety is improved, but control system complexity increases
Solution Approach 1:
The system implements priority-based mediation by changing the parameter of command processing from equal-weighted integration to priority-weighted integration. Each control command is assigned a priority parameter based on driving safety criteria, and the mediation process uses this parameter to determine execution order and weight, improving driving safety while adding only minimal complexity through parameter assignment.
4Speed
If emergency control commands are optimized for fast response, then response time is improved, but control precision may be reduced
Solution Approach 1:
The system applies partial action by selectively optimizing only emergency control commands for fast response while maintaining standard processing for non-emergency commands. When an emergency command is detected, the system bypasses detailed processing steps to achieve fast response, but this optimization is applied partially only to commands meeting emergency criteria, preserving control precision for routine operations while improving response time for critical situations.
