Telematics Unit Standby Notification to Back Office
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telematics units in vehicles consume power even in standby mode, leading to battery drain, and there is a need to notify network applications when the unit will be unavailable as it ends its standby period.
Innovation Solution
A system and method where the telematics unit contacts a 'back office' unit associated with network applications to notify them of its impending end of standby period, allowing for data exchange and user notification, with optional extension of standby time for plug-in vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the telematics unit remains in standby mode to minimize power drain, then energy consumption is reduced, but the unit becomes unavailable for contact after the standby period ends
Solution Approach 1:
The telematics unit initiates contact with the back office before the standby period ends to notify them of impending unavailability. This preliminary action ensures that network applications are aware of the upcoming discontinuation of service, allowing users to be notified and potential service interruptions to be planned for, thus resolving the contradiction by maintaining reliability through advance warning while preserving energy through continued standby operation.
2Reliability
If the telematics unit contacts the back office before ending standby period, then network applications are notified of unavailability, but additional power is consumed during the notification process
Solution Approach 1:
The system implements periodic monitoring of the standby timer and initiates contact only at the optimal moment before the standby period ends. This periodic check ensures that the notification is sent at the most efficient time, minimizing additional power consumption while ensuring reliable notification. The telematics unit wakes up periodically to check the standby timer status and initiates contact only when necessary.

AI summary
The described method and system provide for notification to network applications by a telematics unit in standby mode of when the telematics unit is switching away from standby mode and will be come unavailable for communication with the network applications. The network application may include mobile applications for mobile devices (such as smartphones) and web applications accessible through web pages. The telematics unit may communicate with the back office(s) of the network applications. If the vehicle is a plug-type vehicle, the telematics unit or network application may further extend the standby period of the telematics unit or vehicle when the vehicle is plugged in.
