Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2V and V2I communication technologies are integrated to provide comprehensive safety features, then driving safety and collision avoidance capabilities are improved, but system complexity and integration challenges increase
Solution Approach 1:
The patent combines V2V and V2I communication technologies into a unified ADAS system that processes both vehicle-to-vehicle and vehicle-to-infrastructure messages through a single control unit, enabling comprehensive safety features while managing system integration through standardized communication protocols
Solution Approach 2:
The control unit is designed to handle multiple message types including Basic Safety Messages (BSM) and Infrastructure Messages (IM) through a universal processing architecture that can interpret and act on various communication standards, making the system adaptable to different driving scenarios and infrastructure types
2Adaptability or versatility
If multiple communication standards and message types are processed, then versatility and adaptability to different driving scenarios are improved, but processing complexity and data management challenges increase
Solution Approach 1:
The patent segments the processing of different message types by creating dedicated processing modules for Basic Safety Messages and Infrastructure Messages, allowing each message type to be handled by specialized sub-routines while maintaining a unified control architecture
Solution Approach 2:
The control unit acts as an intermediary between multiple communication standards and the vehicle's existing sensor systems, translating and harmonizing data from V2V and V2I sources into a unified format that can be processed by the vehicle's control systems
3Speed
If real-time processing of safety messages is implemented, then collision avoidance and response time are improved, but computational load and processing time requirements increase
Solution Approach 1:
The system performs preliminary filtering and prioritization of incoming messages to identify critical safety information that requires immediate processing, allowing the control unit to allocate computational resources preferentially to high-priority collision avoidance functions while maintaining real-time response capabilities
