Vehicle Data Relay via Dead Spot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing vehicle data via mobile radio connections are unreliable due to the need to know or estimate driving routes, leading to potential failures in data transmission when the vehicle is parked in areas with no network coverage.
Innovation Solution
A method and system that continuously monitor the signal strength of mobile radio connections to detect and memorize dead spots where the vehicle is parked, allowing for predictive data transmission to a server device before reaching these areas, eliminating the need to know the driving route and ensuring reliable data access even in areas with no coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving route is known or estimated to ensure data transmission, then data transmission reliability is improved, but system complexity increases and fails when route changes occur
Solution Approach 1:
The system performs preliminary actions by detecting and memorizing dead spots during vehicle operation, then uses this stored information to proactively transmit data before the vehicle reaches these areas. This eliminates the need for route knowledge while ensuring transmission reliability, as the system prepares data for transmission in advance based on previously identified problem areas.
Solution Approach 2:
The system serves itself by automatically detecting dead spots during normal operation and using this self-acquired information to improve its own data transmission reliability. The vehicle's own operational data is used to identify transmission problems and implement solutions without external intervention or route information.
2Loss of information
If driving route is estimated to prevent data loss, then information completeness is improved, but measurement precision requirements increase
Solution Approach 1:
The system replaces the mechanical/route-based approach with a signal-strength-based detection system. Instead of relying on precise route estimation, the system uses mobile radio signal strength measurements to automatically identify dead spots, substituting complex route analysis with simple signal detection and memorization.
3Ease of operation
If mobile radio connection is used for data transmission, then ease of operation is improved, but reliability deteriorates in areas without network coverage
Solution Approach 1:
The system performs preliminary data transmission actions before the vehicle enters dead spot areas by detecting signal strength changes and proactively sending data to external servers while still in coverage zones. This ensures data is transmitted in advance, maintaining ease of wireless operation while compensating for reliability issues in coverage-free areas.

AI summary
The present disclosure concerns a system and method with the steps: detecting of the signal strength of a mobile radio connection between the motor vehicle and a mobile radio network at detected positions of the motor vehicle after determining from the detected signal strength that the mobile radio connection has been interrupted and the motor vehicle has been parked as of this time within a predetermined duration: storing of the position of the motor vehicle in which the motor vehicle was situated at the time of the interruption as a dead spot; relaying of vehicle data to a vehicle-external server device as soon as it is determined, after the storing of the dead spot, that the motor vehicle has approached within a given distance of the stored dead spot; providing of the relayed vehicle data by the vehicle-external server device.
