Vehicle Data Transmission Delaying for Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for data transmission between a motor vehicle and a dismounted data transmission unit, such as those using WiFi connections, face challenges in ensuring optimal cost and quality due to uncertain timing and availability of connection modes, leading to potential delays and increased costs.
Innovation Solution
A method that identifies and stores connection modes over a predetermined period, delays data transmission to utilize a preferred connection mode with better speed and lower cost, while informing the user and considering data importance and vehicle location, ensuring timely and cost-effective data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data transmission is performed immediately using the currently available connection mode, then the transmission can be executed without delay, but the transmission cost increases and transmission quality may be suboptimal
Solution Approach 1:
The system performs preliminary tracking and analysis of connection mode timings over a predetermined period to identify patterns and predict future connection modes. This preliminary action enables the system to plan data transmission in advance during optimal connection modes (such as WiFi at home), thereby reducing transmission costs while avoiding excessive delays through intelligent scheduling.
2Loss of energy
If the vehicle is required to be placed close to a WiFi terminal for data transmission, then transmission cost is reduced, but the timing of transmission becomes uncertain and may occur long after the need for transmission
Solution Approach 1:
The system continuously tracks and monitors connection modes over time, building a historical database of connection patterns. This feedback mechanism enables the system to learn and predict when optimal connection modes (like WiFi) will be available in the future, allowing intelligent scheduling of data transmissions that balances cost reduction with timely completion of transmission tasks.
3Loss of energy
If data transmission is delayed to use a preferred connection mode, then transmission cost decreases and quality improves, but the transmission time increases
Solution Approach 1:
The system dynamically adjusts the data transmission schedule based on predicted connection modes, data priority levels, and user-defined preferences. By making the transmission timing flexible and adaptive rather than fixed, the system can optimize for cost and quality when possible, while still meeting time-sensitive requirements when necessary.

AI summary
Method of transmitting data between a vehicle and an off-board data transmission unit (30) of the vehicle, comprising the steps consisting in: - storing possible modes of connection between the vehicle and the off-board data transmission unit (30) of the vehicle which are available over the course of a predetermined time period, - noting tempos of the modes of connection over the predetermined time period, - delaying a data transmission as a function of the tempos of the noted modes of connection, so as to wait to have a mode of connection preferred to that available at an instant at which the data transmission is decided.
