Solution Overview
Problem
Existing vehicle communication systems face challenges in implementing vehicle-to-X (V2X) communication due to high upgrade costs and limited adoption, particularly for emergency vehicles that require reliable communication during emergencies.
Innovation Solution
A communication apparatus utilizing existing radio keyless entry (RKE) technology to enable V2X communication by equipping vehicles with a transceiver capable of wireless data exchange, including position data, warnings, and identification codes, and using store-and-forward systems to bridge gaps in technology adoption, with optional integration of higher bandwidth communication standards like IEEE 802.11p for enhanced data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles are equipped with dedicated V2X communication units, then communication reliability is improved, but cost increases
Solution Approach 1:
The patent reuses existing radio key transceivers for both traditional keyless entry functions and V2X communication functions. The same hardware infrastructure (transceiver, antenna, processor) is utilized for multiple purposes, eliminating the need for dedicated V2X communication units and reducing overall system cost while maintaining communication reliability
Solution Approach 2:
The radio key system, which is already present in modern vehicles for access control, is leveraged to provide V2X communication capabilities. The existing system serves itself by extending its functionality beyond traditional keyless entry to include vehicle-to-vehicle and vehicle-to-infrastructure communication
2Adaptability or versatility
If all vehicles are upgraded with V2X communication technology, then communication coverage is improved, but device complexity increases
Solution Approach 1:
The radio key transceiver performs both traditional access control functions and V2X communication functions using the same hardware platform. This multi-functional approach increases communication coverage without requiring separate dedicated systems, thereby avoiding exponential complexity growth
Solution Approach 2:
The system dynamically adapts its communication mode and protocol based on the operational context - using appropriate communication standards for different V2X scenarios while maintaining backward compatibility with traditional radio key functions, allowing flexible deployment across diverse vehicle types
3Ease of manufacture
If radio key technology is used for V2X communication, then cost is reduced, but data transmission bandwidth is limited
Solution Approach 1:
The communication system is segmented into different functional layers: the radio key transceiver handles basic control signals and position data transmission, while optional higher-bandwidth standards like IEEE 802.11p can be integrated for enhanced data transmission when needed. This segmentation allows cost-effective deployment with scalable bandwidth enhancement
Solution Approach 2:
The patent introduces an intermediary approach where radio key technology serves as the primary communication medium for essential V2X functions, with the option to bridge to higher-bandwidth communication standards for data-intensive applications, thus balancing cost and performance requirements
