Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If automatic steering capability is implemented, then steering precision is improved, but driver control and adaptability to complex situations deteriorate
Solution Approach 1:
The system dynamically switches between manual and automatic steering modes based on detected driver intent and environmental conditions. The automatic engagement envelope adjusts in real-time, allowing the system to be neither fully static nor completely adaptive, but dynamically configurable based on operational context.
Solution Approach 2:
The system continuously monitors driver inputs through steering sensors and camera systems, providing feedback loops that detect when a driver intends to initiate an evasive maneuver. This feedback mechanism allows the system to recognize driver intent and appropriately engage or disengage automatic steering assistance.
2Reliability
If multiple assessors are implemented to evaluate complex conditions, then safety is improved, but system complexity increases
Solution Approach 1:
The safety assessment system is segmented into multiple independent assessors, each responsible for evaluating specific conditions (allowable passing window, vehicle dynamics, lane topology, vulnerable road users, timely intent, scene actors). This modular segmentation allows comprehensive safety evaluation while maintaining manageable system complexity through division of labor.
Solution Approach 2:
The processor executes multiple assessors that perform different functions but collectively contribute to the overall safety determination for evasive steering maneuvers. Each assessor is a universal component that can evaluate its specific aspect and contribute to the composite decision-making process.
3Loss of time
If automatic evasive steering maneuver completion is implemented, then response time is improved, but driver intent accuracy may deteriorate
Solution Approach 1:
The system performs preliminary assessment of driver intent through multiple sensors (steering sensors, cameras) before automatically completing the evasive maneuver. By detecting driver intent in advance and validating it through multiple assessors, the system ensures accurate interpretation of driver intentions while maintaining rapid response capability when the intent is confirmed.
