Mobile Device Emergency Location Reporting via Vehicle Data Handoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular computing systems terminate their functionality when the user leaves the vehicle, failing to seamlessly integrate in-vehicle experiences with extra-vehicular activities, and emergency reporting systems do not effectively track user location after an accident.
Innovation Solution
A system and method that utilize a processor in a mobile device to continue application functionality and report user location by receiving data from a vehicle computing system, accessing emergency contacts, and periodically updating GPS coordinates until the user reaches a destination, enabling seamless interaction between in-vehicle and out-of-vehicle experiences and enhancing emergency response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the vehicle computing system terminates functionality when the user leaves the vehicle, then the system complexity is reduced and energy consumption is lowered, but the user experience continuity and emergency tracking capability are degraded
Solution Approach 1:
The system is segmented into two independent components: the vehicle computing system that handles in-vehicle operations, and the mobile device that handles extra-vehicular operations. The mobile device contains a local copy of the application and data, allowing it to function independently when the user leaves the vehicle. This segmentation resolves the contradiction by enabling continuity of service without requiring the vehicle system to remain active.
Solution Approach 2:
The mobile device acts as an intermediary between the vehicle computing system and the user outside the vehicle. It receives data from the vehicle system before departure, stores it locally, and continues to provide application functionality and emergency tracking capabilities independently. This intermediary approach allows the vehicle system to terminate operations while maintaining user experience continuity.
2Reliability
If the vehicle computing system continues to communicate with the emergency responder after the user leaves the vehicle, then the emergency response capability is improved, but the energy consumption and system resource usage increase
Solution Approach 1:
The mobile device performs preliminary actions by receiving and storing emergency contacts and application data from the vehicle computing system before the user leaves the vehicle. This pre-loading enables the mobile device to independently maintain emergency communication capabilities without requiring continuous power from the vehicle system, thus improving reliability while reducing energy consumption.
Solution Approach 2:
The mobile device is designed to be self-sufficient for emergency reporting functions. It contains local copies of emergency contacts, application data, and GPS tracking capabilities, allowing it to autonomously maintain communication with emergency responders without requiring continuous power or resources from the vehicle computing system.
3Adaptability or versatility
If the mobile device continues application functionality outside the vehicle, then the user experience continuity is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The essential application data, emergency contacts, and core functionality are extracted from the vehicle computing system and transferred to the mobile device. This extraction enables the mobile device to provide continuous application functionality with reduced complexity, as it only needs to handle the essential subset of functions rather than the complete vehicle system.
4Measurement precision
If GPS location updates are continuously reported after an accident, then the emergency response accuracy is improved, but the data transmission volume and energy usage increase
Solution Approach 1:
The mobile device implements periodic GPS location updates rather than continuous transmission. It reports location at scheduled intervals to the emergency responder, which maintains sufficient accuracy for emergency response while significantly reducing data transmission volume and energy consumption compared to continuous monitoring.

AI summary
A system includes a processor configured to receive instructions from a vehicle computing system (VCS) to being reporting a mobile device location. The processor is also configured to access a list of emergency contacts. Further, the processor is configured to determine that a mobile device has left a predetermined perimeter around a last known vehicle location. The processor is additionally configured to periodically report mobile device GPS coordinates to members of the emergency contacts list, until the mobile device reaches a destination.
