Telematics Unit Pairing with Missing Device Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telematics systems in vehicles do not fully leverage their communication capabilities to provide users with additional services such as forgotten phone notifications and vehicle theft alerts.
Innovation Solution
Implementing a method within telematics units to activate a configurable device pairing program module that uses short-range wireless technology to detect paired mobile devices and provide notifications when they are not within range, allowing for forgotten phone and vehicle theft notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional telematics systems only provide basic services, then system complexity is low, but additional security services like forgotten phone notifications and vehicle theft alerts cannot be provided
Solution Approach 1:
The telematics unit is designed to perform multiple functions beyond basic connectivity, including device pairing detection, exception state identification, and multiple types of notifications (forgotten phone alerts, vehicle theft alerts). This multi-functionality approach allows a single system to provide diverse services without requiring separate dedicated systems for each function.
Solution Approach 2:
The system performs preliminary actions by establishing device pairing relationships in advance and configuring exception state parameters before actual security events occur. The telematics unit proactively monitors for missing paired devices and prepares notification mechanisms ahead of time, enabling rapid response when security-relevant events happen.
2Measurement precision
If the telematics unit continuously monitors for paired mobile devices, then detection capability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system employs periodic detection cycles where the telematics unit checks for the presence of paired mobile devices at intervals. The exception state parameter triggers notifications based on these periodic checks, allowing the system to maintain detection capability while consuming less energy compared to continuous monitoring.
3Loss of information
If the system provides detailed notifications about device absence, then information completeness is improved, but false alarms may increase
Solution Approach 1:
The system applies different quality levels of notification based on the specific exception state detected. Rather than providing uniform detailed notifications for all device absence events, the system tailors the notification content and delivery method to the specific context (e.g., forgotten phone versus vehicle theft), improving information relevance while reducing unnecessary false alarms through contextual filtering.

Implementation Method 1
determining, using the configurable device pairing program module and short-range wireless unit, whether the paired mobile device is within range of the short-range wireless unit
Data Source
AI summary
The described method and system provide for forgotten phone notification and vehicle theft notification. A method includes: activating a configurable device pairing program module associated with a short-range wireless unit of the telematics unit when a triggering condition is satisfied; determining, using the configurable device pairing program module and short-range wireless unit, whether the paired mobile device is within range of the short-range wireless unit; and providing, in response to a determination that the paired mobile device is not within range of the short-range wireless unit, a notification to the paired mobile device that the vehicle is being operated in the exception state that is based, at least in part, upon the paired mobile device not being detected during the determining step.
