Portable V2X Vehicle Interface for Legacy Fleet Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of devices that can be easily installed on legacy vehicles to enable them to interface with autonomous vehicle data streams and contribute to connected vehicle networks without requiring modifications to the vehicle, and existing solutions do not adequately integrate diagnostic functions or allow for real-time sensing and actuation of safety hazards.
Innovation Solution
A portable automotive vehicle communication device that engages with a vehicle's electrical system via a license plate or diagnostic port, using a micro computing unit to derive and communicate V2X data streams, sensor information, and diagnostic data, and includes a cellular network for remote evaluation, allowing the vehicle to receive and act on safety information and contribute to the connected vehicle network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable communication device is installed on a legacy vehicle to enable V2X data stream interfacing, then the vehicle's ability to participate in connected vehicle networks is improved, but the device complexity and installation requirements increase
Solution Approach 1:
The portable communication device is designed to interface with multiple vehicle systems simultaneously - it can connect to the electrical system via license plate fasteners, access diagnostic information through OBD ports, receive GPS location data, and transmit V2X data streams. This multi-functional design allows a single device to perform numerous functions that would otherwise require separate systems, thereby improving vehicle network participation without proportionally increasing device complexity
Solution Approach 2:
The portable communication device acts as an intermediary between legacy vehicles and autonomous vehicle data streams. It translates and bridges communication protocols, allowing legacy vehicles to participate in V2X networks without requiring complex modifications to the vehicle itself. The device mediates between the vehicle's existing systems and the external connected vehicle network, simplifying the integration process
2Difficulty of detecting and measuring
If diagnostic functions are integrated into the portable communication device, then the diagnostic capabilities are improved, but the device complexity increases
Solution Approach 1:
The patent combines diagnostic functions with the portable communication device by connecting it to the vehicle's OBD (On-Board Diagnostics) system. This merging allows the communication device to access diagnostic information, sensor data, and vehicle status without requiring a separate diagnostic tool. The diagnostic capabilities are integrated into the same hardware that handles V2X communication, thereby improving diagnostic capability while minimizing additional complexity through shared components
3Adaptability or versatility
If the device communicates with the vehicle electrical system, then the integration with vehicle systems is improved, but the installation complexity and potential vehicle modifications increase
Solution Approach 1:
The portable communication device is designed as a segmented, modular system that can be installed without permanent modifications to the vehicle. It uses license plate fasteners as mounting points and connects to existing vehicle systems (electrical system, OBD port, GPS antenna) through separate, detachable interfaces. This segmentation allows the device to be easily installed and removed without affecting the vehicle's original structure, thereby improving system integration while maintaining installation ease
Data Source
AI summary
An aftermarket vehicle communication device engageable to a vehicle for providing location information associated with the vehicle to a V2X data stream. The device includes a housing configured to be detachably engageable to the vehicle. A GPS circuit is coupled to the housing and is disposable in communication with a GPS system to receive a GPS signal therefrom, with the received GPS signal being representative of a location of the vehicle when the housing is engaged to the vehicle. An antenna circuit is also coupled to the housing and is in communication with the GPS circuit. The antenna circuit is configured to receive the GPS signal from the GPS circuit and communicate the GPS signal to the V2X data stream.
