Vehicle Emergency Call Data Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for making emergency calls from motor vehicles do not efficiently convey and analyze state data from vehicle components alongside image data, limiting the reliability and speed of response to emergency situations.
Innovation Solution
Embedding state data into an image signal using a predetermined encoding standard, such as JPEG or MPEG-4/AVC, allows for easy analysis and transmission of vehicle component data alongside image data to a vehicle-external facility, enabling quicker and more informed emergency responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If state data and image data are transmitted separately during an emergency call, then the completeness of information is improved, but the complexity of data processing and analysis at the external facility increases
Solution Approach 1:
The patent combines state data and image data into a single integrated data structure that is transmitted together during the emergency call. This merging approach maintains complete information while simplifying processing at the external facility, as the data arrives in a unified format ready for immediate analysis without requiring separate handling of multiple data streams.
Solution Approach 2:
The emergency call system is designed to handle multiple types of data (image data from cameras and state data from vehicle sensors) through a single transmission channel and data structure. This multi-functional approach allows the system to convey comprehensive information while maintaining a streamlined processing architecture at the external facility.
2Reliability
If multiple data types are transmitted during an emergency call, then the reliability of emergency response is improved, but the transmission time and processing speed may be reduced
Solution Approach 1:
The system performs preliminary organization and integration of state data and image data into a standardized format before transmission during the emergency call. This pre-processing ensures that all necessary information is ready for immediate analysis upon receipt, maintaining high processing speed while ensuring complete and reliable data transmission for accurate emergency response.
Data Source
AI summary
The invention relates to a method for operating a motor vehicle, in which an emergency call of the motor vehicle is made and, through the emergency call, image data from at least one camera of the motor vehicle and state data from at least one vehicle component, which differs from the camera of the motor vehicle are sent out to a vehicle-external facility, wherein the state data is, before being conveyed to the vehicle-external facility, embedded into an image signal formed from the image data in accordance with a predetermined image coding standard, and the image signal with the embedded state data is sent out to the vehicle-external facility.
