Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent C-V2X OBU technology is implanted in intelligent vehicles, then V2V, V2P, V2I and V2N functions are supported, but device complexity increases
Solution Approach 1:
The patent merges the C-V2X OBU functionality with the existing intelligent cockpit system by integrating the vehicle networking module into the cockpit domain controller. This consolidation allows the system to perform both cockpit control and V2X communication functions through a unified platform, reducing the number of separate components and simplifying the overall system architecture while maintaining full V2V, V2P, V2I and V2N communication capabilities
2Adaptability or versatility
If multiple vehicle-mounted gateways are equipped for domain communication, then communication interconnection is achieved, but device complexity and cost increase
Solution Approach 1:
The patent implements a multi-functional gateway design where the cross-domain gateway module serves multiple purposes: it acts as a communication gateway between different domains (cockpit, driving control, body control), functions as a data routing hub, and provides protocol conversion capabilities. This single multi-functional gateway replaces what would traditionally require multiple separate gateways, thereby reducing system complexity while maintaining comprehensive domain communication interconnection
3Measurement precision
If multiple sensing devices are added for autonomous driving, then detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent integrates multiple sensing devices (radars, cameras, sensors) into a unified intelligent cockpit system architecture. The cross-domain gateway module consolidates data from various sensing sources and routes it to the appropriate processing units. This merging approach maintains comprehensive detection capabilities while reducing system complexity by eliminating the need for separate dedicated processing systems for each sensor type
4Device complexity
If vehicle-based sensors alone are used for autonomous driving, then system simplicity is maintained, but detection reliability deteriorates in occlusion and extreme weather
Solution Approach 1:
The patent introduces the cross-domain gateway module as an intermediary that facilitates communication between the intelligent cockpit system and external devices (roadside units, other vehicles). This intermediary enables the system to receive supplementary information from external sources, compensating for the limitations of vehicle-based sensors in occlusion and extreme weather conditions while maintaining overall system simplicity
