Solution Overview
Problem
Connected vehicles face challenges in maintaining reliable data processing and communication while moving, as existing technologies struggle to manage connectivity errors and switch between different communication protocols efficiently, leading to potential delays in data processing.
Innovation Solution
A computer-implemented method and system for vehicle data processing that detects connectivity errors and switches between different communication protocols, such as cellular and Wi-Fi, to ensure continuous data processing by identifying the protocol type of a secondary connection and resuming data transmission based on its type, allowing for uninterrupted data processing for a predetermined period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication protocol connection is used for data processing in a connected vehicle, then the system complexity is low, but the reliability of data processing deteriorates when connectivity errors occur
Solution Approach 1:
The patent combines multiple communication protocol connections (cellular and Wi-Fi) into a unified connection management system. The vehicle communication device maintains multiple simultaneous connections to remote servers using different protocols, and merges their functionality to provide redundant data processing paths, thereby improving reliability without requiring separate independent systems.
Solution Approach 2:
The system dynamically changes connection parameters by switching between different communication protocols (cellular vs. Wi-Fi) based on connection status. When a connectivity error is detected on one protocol, the system changes the active connection parameter to use an alternative protocol, maintaining data processing reliability through parameter adaptation.
2Reliability
If multiple communication protocols are managed to ensure continuous connectivity, then the reliability of data processing improves, but the device complexity increases
Solution Approach 1:
The connection management system operates autonomously by self-detecting connectivity errors and automatically switching between communication protocols without requiring external intervention. The vehicle communication device monitors its own connection status and performs protocol switching independently, reducing the need for complex external control mechanisms.
Solution Approach 2:
The system implements feedback mechanisms where connection status information is continuously monitored and fed back to the connection manager. When connectivity errors are detected through feedback from the communication interfaces, the system automatically adjusts by switching protocols, creating a closed-loop control system that manages complexity through intelligent feedback response.
3Productivity
If connection switching is performed quickly to maintain continuity, then the productivity of data processing is maintained, but the measurement precision of connection protocol identification deteriorates
Solution Approach 1:
The system performs preliminary identification of the second connection's protocol type before resuming data processing. By detecting and identifying the protocol type (cellular or Wi-Fi) in advance, the system ensures accurate protocol recognition while maintaining quick switching capability, preventing delays caused by protocol misidentification.

AI summary
A computer-implemented method for wireless vehicle data processing includes processing data requests from a communication device in a vehicle over a network using a first connection established between the communication device and an off-board server. Further, the method includes detecting a connectivity error between the communication device and the off-board server based on the first connection and detecting a second connection different than the first connection. A connection protocol type is identified for the second connection and processing of the data requests are resumed over the network via the second connection for a predetermined period of time based on the connection protocol type of the second connection.
