Vehicle Mobile Device Coordination via GPS Proximity Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle telematics systems often require the vehicle owner to be inside the vehicle to establish a connection with their mobile device, limiting remote control capabilities and causing confusion when multiple devices are proximate to the vehicle, leading to errors and unauthorized connections.
Innovation Solution
A system that uses a processor to receive and compare GPS coordinates, page the vehicle computing system to connect with a mobile device upon proximity, and prioritize connections based on device ranking to ensure authorized access and prevent unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the vehicle waits for a known device to come into reception proximity before establishing connection, then power consumption is reduced, but the device cannot be connected to the vehicle before the owner enters the vehicle
Solution Approach 1:
The vehicle performs preliminary actions by maintaining a powered state and continuously monitoring for devices even before the owner enters. The system proactively pages for devices and establishes connections before the owner physically enters the vehicle, enabling remote control capabilities while managing power through intelligent standby modes rather than complete shutdown.
2Adaptability or versatility
If the vehicle connects to multiple devices simultaneously, then more users can access vehicle features, but connection management becomes complex and unauthorized connections may occur
Solution Approach 1:
The system segments device connections into hierarchical levels: primary devices (owner's device) and secondary devices (guest devices). Each device type has specific permissions and access levels. The vehicle can maintain multiple connections simultaneously but manages them through segmented permission structures, where primary devices have full access and secondary devices have limited access, simplifying connection management while maintaining versatility.
3Speed
If the vehicle pages continuously for devices, then connection establishment is faster, but power consumption increases
Solution Approach 1:
The vehicle implements periodic paging instead of continuous paging, sending out connection requests at scheduled intervals when in standby mode. When the vehicle is active or a device is detected in proximity, the paging frequency increases to establish connection faster. This periodic approach balances power consumption with connection speed by adapting the paging interval based on vehicle state and detection needs.

AI summary
A system includes a processor configured to receive vehicle GPS coordinates. The processor is also configured to compare the received GPS coordinates to known device coordinates. Further, the processor is configured to page a vehicle computing system, requesting connection, if the vehicle coordinates and the known device coordinates are within a predetermined proximity and connect to the vehicle upon receipt of a response message from the vehicle.
