Vehicle Communication System Selective Voice Connection Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-infrastructure communication systems lack efficient mechanisms to filter out unwanted infrastructure facilities and vehicles, leading to unnecessary participation in communication, and do not allow for selective establishment of voice connections based on specific events or criteria.
Innovation Solution
A communication system for vehicles and infrastructure facilities that includes a control unit and communication unit capable of inquiring about and rejecting voice connections based on predefined criteria, with vehicle sensor systems triggering inquiries for specific events, and allowing drivers to manage lists of authorized communication partners, enabling selective and automated voice connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle communication system establishes voice connections with all infrastructure facilities that transmit data, then the coverage and availability of communication are improved, but unwanted infrastructure facilities participate in communication causing interference and inefficiency
Solution Approach 1:
The system performs preliminary verification by checking whether the infrastructure facility's identification is included in the stored list of authorized facilities before establishing a voice connection. This preliminary action prevents unwanted facilities from participating in communication, resolving the contradiction between broad coverage and communication reliability.
2Measurement precision
If the vehicle communication system manually manages communication partner lists, then the precision of selective communication is improved, but the complexity of operation increases
Solution Approach 1:
The system automatically receives infrastructure facility identification data, stores it in the list without requiring manual intervention. This self-service approach maintains high selective communication precision while eliminating manual list management operations, resolving the contradiction between precision and ease of operation.
3Productivity
If the vehicle communication system automatically establishes voice connections when criteria are met, then the productivity of communication establishment is improved, but the risk of unwanted connections increases
Solution Approach 1:
The system incorporates feedback by continuously checking whether the received infrastructure facility identification matches the stored list before automatically establishing a voice connection. This feedback mechanism ensures that automatic connection establishment maintains both high productivity and high reliability by preventing unwanted connections.

AI summary
Disclosed herein is a communication system for a vehicle for communicating with nearby vehicles which includes a control unit and a communication unit. After a triggering event occurs, an inquiry is sent to nearby vehicles whether a communication voice connection is to be established. Nearby vehicles can thereupon offer the establishment of the voice connection. This establishment can be accepted or rejected by the communication system.
