Vehicle Communication Scenario Determination for Direct Safety Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication systems face challenges in determining the registration plate numbers of nearby vehicles, especially under adverse weather conditions or when vehicles are not standardized, leading to inefficiencies and safety concerns due to reliance on remote servers for indirect communication, which consumes energy and network resources.
Innovation Solution
A method for determining a communications scenario that allows direct communication between vehicles by identifying neighboring elements based on their geolocation, speed, and direction, using a table of correspondence to select appropriate actions and messages, thereby reducing network congestion and improving user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If indirect communication through remote server is used, then communication coverage is improved, but network congestion increases and response time deteriorates
Solution Approach 1:
The patent segments communication into two types: indirect communication through remote server for non-urgent information, and direct communication between vehicles for urgent safety-critical information. This segmentation allows the system to maintain communication coverage while avoiding network congestion for time-sensitive messages.
Solution Approach 2:
The patent introduces a direct communication channel as an intermediary solution for urgent messages, bypassing the remote server intermediary for safety-critical communications. This dual-channel approach maintains the mediator's role for general communication while enabling direct peer-to-peer communication when needed.
2Measurement precision
If registration plate number determination is used, then vehicle identification is achieved, but reliability deteriorates under adverse weather conditions
Solution Approach 1:
The patent uses virtual copies of vehicle data stored in the remote server as a backup identification method. When optical recognition of registration plates fails due to adverse conditions, the system retrieves vehicle identification information from the server's database using alternative methods such as geolocation data.
Solution Approach 2:
The patent changes the identification parameters from visual-based (registration plate recognition) to data-based (geolocation, vehicle characteristics) when weather conditions are adverse. This parameter switching maintains identification reliability across different environmental conditions.
3Loss of information
If remote server consultation is performed periodically, then information availability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic communication with the remote server only when necessary, rather than continuous periodic consultations. Direct communication between vehicles eliminates the need for periodic server consultations for safety-critical information exchange, reducing energy consumption while maintaining information availability.

AI summary
A method for determining a communications scenario corresponding to an action for producing, by a first movable element situated in a traffic lane, a response to an event. The method includes: determining an event in a vicinity of the first movable element, depending on at least one neighbouring element from a list of neighbouring elements positioned in the vicinity; determining a series of actions able to be performed in response to the event, by consulting a lookup table between at least one event and at least one series of actions; for at least one action of the series of actions, determining a communications scenario associated with the action, the determining a scenario including a sub-step of selecting, in the list of elements, for at least one communications scenario message, at least one neighbouring element receiving the message.
