Vehicle Communication System Emergency Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle systems face challenges in reliably transmitting critical vehicle parameter data to emergency response centers during emergencies, particularly when data transmission fails, and may not adapt language for effective communication with emergency responders based on the vehicle's location.
Innovation Solution
A vehicle communication system that automatically detects emergency conditions, attempts data transmission using multiple modulation schemes, and converts data to speech signals for transmission over a voice channel if initial data transmission fails, while also determining the appropriate language for communication based on the vehicle's location to ensure effective emergency response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission is attempted using standard data protocols, then transmission speed is improved, but reliability deteriorates when transmission fails
Solution Approach 1:
The system changes the transmission parameter from digital data packets to speech signals when data transmission fails. The processor converts vehicle parameter data into speech signals and transmits them over the voice channel, effectively changing the medium and parameters of transmission to ensure reliability while maintaining speed through automated conversion.
2Reliability
If automated voice communication is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The processor performs multiple functions: it processes emergency detection sensor data, gathers vehicle parameter data, attempts data transmission, converts data to speech signals, and manages the communication protocol. By making the processor multi-functional, the system improves reliability without proportionally increasing device complexity.
3Adaptability or versatility
If language adaptation based on location is added, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by determining the vehicle's geographic location and selecting the appropriate language for emergency communication before the actual voice transmission occurs. This preparation ensures adaptability to different regions and languages while managing complexity through automated location-based language selection.

Data Source
AI summary
A vehicle communication system includes one or more processors configured to output a computer generated speech signal for at least a portion of vehicle parameter data based on at least one condition detection signal. The one or more processors are further configured to output the speech signal to a call center over a voice channel via a wireless communication. The one or more processors are further configured to receive a geographic location of a vehicle so that the speech signal is in a selected language based on a language associated with the geographic location of the vehicle.
