Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving systems rely only on V2X communication for object detection, then communication efficiency is improved, but detection coverage is reduced because objects incapable of V2X communication cannot be detected
Solution Approach 1:
The electronic device acts as an intermediary between objects incapable of V2X communication and the autonomous vehicle. It detects objects using sensors, determines their communication capability, and transmits information about undetectable objects to the vehicle, thereby extending detection coverage without requiring all objects to have V2X communication capabilities
Solution Approach 2:
The system segments object detection into two pathways: objects capable of V2X communication are detected through communication signals, while objects incapable of V2X communication are detected through sensor-based observation by the electronic device. This segmentation allows the system to handle different object types through appropriate detection methods
2Loss of information
If the electronic device transmits information about all detected objects, then information completeness is improved, but communication load increases
Solution Approach 1:
The electronic device applies different information transmission strategies based on the specific characteristics of each object. For objects incapable of V2X communication, it transmits detailed information including position, movement state, and predicted trajectory. For objects already detectable through V2X, it transmits only supplementary information, thereby reducing overall communication load while maintaining information completeness
3Measurement precision
If the system uses multiple sensors for comprehensive object detection, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The electronic device integrates multiple sensors (camera, radar, lidar, infrared) that can detect various types of objects including vehicles, pedestrians, animals, and obstacles. These sensors serve multiple functions: detecting object position, determining movement state, identifying object type, and predicting trajectories, thereby achieving comprehensive detection accuracy without proportionally increasing system complexity
