Telematics Controller Voice Communication via Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data-only telematics systems in vehicles lack voice communication capabilities, which are essential for emergency situations and other voice-related features, despite offering advanced automatic crash notification and remote control functionalities.
Innovation Solution
A system that utilizes a mobile device connected via Bluetooth or other means to a telematics controller, allowing for voice communication by identifying and transmitting caller ID information to a service provider, enabling seamless integration of voice and data capabilities, even in data-only telematics setups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a data-only telematics system is used, then cost is reduced and device complexity is minimized, but voice communication capability is lost
Solution Approach 1:
The patent introduces a mobile device as an intermediary component that bridges the gap between the data-only telematics system and voice communication needs. The mobile device receives crash data from the telematics system and handles voice calls through its cellular capabilities, allowing the simple telematics system to provide comprehensive emergency communication without needing built-in voice hardware
Solution Approach 2:
The system achieves multi-functionality by combining the data transmission capabilities of the telematics system with the universal communication capabilities of a mobile device. The mobile device serves multiple functions including receiving crash notifications, providing voice communication, and acting as a contact point for emergency services, thereby eliminating the need for dedicated voice hardware in the telematics system
2Adaptability or versatility
If voice capabilities are integrated into the telematics system, then voice communication is enabled, but system complexity and cost increase
Solution Approach 1:
The patent extracts the voice communication function from the telematics system and places it in a separate mobile device. The telematics system retains only its core data transmission function, while the mobile device handles all voice-related operations, thereby reducing telematics system complexity while maintaining comprehensive functionality
Solution Approach 2:
The mobile device acts as an intermediary that handles all complex voice communication protocols and hardware interactions, shielding the simple telematics system from complexity while enabling full voice capability through the integrated system
3Reliability
If caller ID information is transmitted to the service provider, then emergency response efficiency is improved, but data transmission requirements increase
Solution Approach 1:
The system transmits only the essential caller ID information (phone number) rather than complete contact profiles or additional metadata. This partial transmission approach provides sufficient information for emergency responders to contact the vehicle owner while minimizing data transmission volume and maintaining efficiency
Solution Approach 2:
The mobile device's phone number is captured and stored in advance before any emergency occurs. This preliminary capture of identification information ensures that when a crash occurs, the data is already available for immediate transmission to the service provider, improving response efficiency without requiring real-time data gathering
Data Source
AI summary
A system and method for providing voice communication to an occupant of a vehicle through a mobile device. The system communicates with a mobile device with an occupant of the vehicle, for example using a telematics controller or network access device. The system receives an identification from the mobile device and transmits a request, as well as, the identification to a service provider. The service provider then initiates a communication to the mobile device based on the request and identification.
