Vehicle Infotainment Cloud-Assisted Mobile Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle telematics systems lose functionality when a mobile device is not connected, causing user frustration due to the inability to access features like navigation and remote vehicle control.
Innovation Solution
A system that uses a processor to detect vehicle events and establish cloud-assisted communication with a mobile device, allowing for seamless reconnection and continued functionality even when a local wireless connection is not established, by instructing the device to pair with the vehicle infotainment system through a remote server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device is connected to the vehicle infotainment system through short-range wireless communication, then full functionality (navigation, remote control, etc.) is available, but the system becomes dependent on the device being connected and paired
Solution Approach 1:
The patent introduces a remote server as an intermediary between the vehicle and the mobile device. When the device is not connected locally, the vehicle modem communicates with the remote server, which then relays commands and data to the mobile device via cellular network, enabling functionality without direct local connection
Solution Approach 2:
The system separates the communication path into two segments: local short-range wireless communication for direct connection, and remote cellular-based communication through a server for indirect connection. This segmentation allows the system to operate through either path depending on connection status
2Productivity
If the system requires local wireless connection for full functionality, then communication speed and responsiveness are high, but functionality is lost when the device is not connected
Solution Approach 1:
The system dynamically switches between two communication modes: local wireless mode for high-speed communication when connected, and remote server-mediated mode for continued functionality when disconnected. The processor detects connection status and automatically selects the appropriate communication path
Solution Approach 2:
The system performs preliminary pairing between the vehicle and mobile device, storing connection information in advance. This preliminary action enables the remote server to later relay commands to the device even when direct connection is not established at the moment of use
3Device complexity
If the vehicle uses only local wireless communication for device connectivity, then the system remains simple, but features become inaccessible when no device is connected
Solution Approach 1:
The vehicle infotainment system is designed to perform multiple functions through two different communication paths: local wireless communication for direct device interaction, and remote cellular communication through a server for indirect device interaction. This multi-functionality ensures features remain accessible regardless of connection type
Data Source
AI summary
A system includes a processor configured to receive a vehicle event and determine a wireless device present connection state relative to a vehicle infotainment system. The processor is further configured to communicate with a remote server through a vehicle modem, including transmission of the wireless device present connection state, based on the occurrence of the vehicle event. The processor may also be configured to request that the remote server instruct a wireless device to pair with a vehicle infotainment system if the wireless device present connection state indicates the wireless device is not presently paired.
