Vehicle Connection Maintenance System for Wireless Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth connection systems often connect to unintended vehicles when not needed and disconnect from needed vehicles, leading to unreliable connections between portable devices and vehicle systems.
Innovation Solution
A vehicle connection maintenance system that includes a receiver, transmitter, and electronic controller to maintain wireless connections between portable devices and vehicle systems, using an external server and sensors to prevent connections to remote vehicles when the device is already connected to a primary vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable device automatically connects to any available vehicle system when in range, then connection establishment is simplified and faster, but the device may connect to unintended remote vehicles instead of the primary vehicle, causing connection instability
Solution Approach 1:
The patent introduces a connection maintenance system with transmitters and receivers as intermediaries. The primary vehicle continuously transmits its identifier and connection status, and the portable device's receiver monitors these signals. This intermediary mechanism ensures the device connects only to the intended primary vehicle rather than any available vehicle, resolving the contradiction between easy automatic connection and reliable stable connection.
2Reliability
If the portable device maintains continuous wireless connection to the primary vehicle, then connection reliability is improved, but the device cannot connect to remote vehicles when needed, reducing system adaptability
Solution Approach 1:
The patent implements dynamic connection management where the portable device can switch between connected and disconnected states based on real-time conditions. The system monitors the primary vehicle's connection status and geographic proximity, allowing the device to maintain stable connections when appropriate and disconnect when the primary vehicle is unavailable, thus achieving both reliability and adaptability.
Solution Approach 2:
The connection maintenance system uses feedback mechanisms where the transmitter continuously sends connection status and identifier information back to the portable device. This feedback loop allows the device to make informed decisions about maintaining or breaking connections, ensuring stable connections to the primary vehicle while preserving the ability to adapt to changing situations.
3Reliability
If the system monitors and maintains connection status continuously, then connection reliability is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The patent implements a self-service monitoring system where the primary vehicle's transmitter automatically broadcasts its identifier and connection status without requiring active querying from the portable device. The portable device's receiver passively monitors these broadcasts, reducing the complexity of continuous monitoring while maintaining connection reliability through automatic status updates.

AI summary
A vehicle connection maintenance system includes a receiver, a transmitter, an electronic controller. The receiver is disposed in a vehicle and is configured to receive a signal from a portable device to enable the portable device to wirelessly connect to a connection system in the vehicle. The transmitter is disposed in the vehicle and is configured to transmit information related to the portable device. The electronic controller is configured to the cause the transmitter to transmit information when the receiver has received the signal from the portable device and the portable device is connected to the connection system of the vehicle to maintain wireless connection between the portable device and the connection system of the vehicle and prevent the portable device from wirelessly connecting to a remote system, the information indicating that the portable device is wirelessly connected to the connection system in the vehicle.
