Vehicle Peer-to-Peer Route Information Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic information systems often lose valuable details for individual drivers due to the compilation of data, making it difficult for drivers to receive real-time information about specific traffic situations or road conditions, such as traffic jams or weather effects on secondary roads.
Innovation Solution
A peer-to-peer network is used to connect vehicles, allowing them to directly share real-time route information, such as camera data and sensor information, enabling drivers to dynamically adapt their route selection and driving behavior by accessing current conditions from other vehicles or smartphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traffic information is compiled in a central database, then information can be aggregated and processed centrally, but valuable details for individual drivers are lost
Solution Approach 1:
The patent segments the centralized information system into distributed peer-to-peer nodes (vehicles and smartphones). Each node maintains its own route information independently rather than consolidating all data centrally. This segmentation allows individual drivers to access specific, detailed information from nearby vehicles without requiring central compilation, thus preserving information details while maintaining system efficiency.
Solution Approach 2:
The patent introduces a spatial dimension to information access by implementing location-based peer-to-peer communication. Instead of centralized temporal processing, vehicles exchange route information directly based on their geographic proximity and route overlap. This dimensional shift enables drivers to obtain detailed, real-time information from vehicles currently experiencing the same traffic conditions, preserving information granularity while improving access efficiency.
2Reliability
If real-time route information is transmitted between vehicles, then drivers can access current traffic conditions, but network complexity increases
Solution Approach 1:
The patent makes vehicles and smartphones universal nodes in the peer-to-peer network, each capable of both transmitting and receiving route information. This multi-functionality simplifies the network structure by eliminating dedicated servers or control nodes - any vehicle can act as an information source or recipient. The standardized communication protocol allows heterogeneous devices (vehicles and smartphones) to interact uniformly, reducing overall system complexity while maintaining real-time information reliability.
3Adaptability or versatility
If detailed route information is made available to all drivers, then individual driving decisions can be optimized, but data transmission requirements increase
Solution Approach 1:
The patent implements local quality by providing route information specifically tailored to each driver's context - only vehicles on the same or overlapping routes exchange information. Each driver receives detailed information relevant to their specific route and location, not universal traffic data. This contextual filtering reduces data transmission volume significantly while maintaining high adaptability for individual route optimization decisions.
Data Source
AI summary
Current route information about a traffic situation and/or the state of the route itself is made available. A communication link to a peer-to-peer network is set up by a communication device of a motor vehicle, and the motor vehicle is signed on to said peer-to-peer network as a subscriber of the peer-to-peer network, with the result that a communication address of the motor vehicle can be determined by at least one other subscriber of the peer-to-peer network. Furthermore, in each case an interrogation relating to the route information is received by the communication device from the at least one other subscriber. The route information itself is determined by a sensing device of the motor vehicle and is then transmitted to the interrogating subscriber by the communication device.
