Telematics Unit Personalized Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicular telematics systems, the increasing use of shared vehicles and multiple users per vehicle leads to personalized data being optimized for the wrong user, resulting in suboptimal services and unauthorized access to previous users' data.
Innovation Solution
A system and method for managing personalized data in telematics units, allowing users to securely remove or transfer their data through a human-machine interface, using a telematics unit and an operations control center, ensuring data is erased or updated based on user authentication and vehicle key connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personalized data is stored locally in the telematics unit for service customization, then service personalization is improved, but data privacy and security are worsened due to unauthorized access by subsequent users
Solution Approach 1:
The system performs preliminary actions by detecting when a vehicle key is removed and automatically initiating data removal processes before the next user accesses the vehicle. This proactive approach ensures that personalized data is cleared in advance, preventing unauthorized access while maintaining service personalization during the current user's session.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring vehicle key status and user presence. When the key is removed or another user is detected, the system receives feedback and automatically responds by removing personalized data, creating a closed-loop system that dynamically adjusts data retention based on real-time conditions.
2Duration of action of stationary object
If personalized data is retained in the telematics unit for multiple users, then service continuity is improved, but data privacy and user authentication are worsened
Solution Approach 1:
The system applies dynamics by making data retention flexible rather than static. Personalized data is retained dynamically based on detected user presence and key status - data is kept when the authorized user is present and automatically removed when the key is removed or another user is detected, allowing the system to adapt retention duration to actual usage conditions.
Solution Approach 2:
The system performs self-service by automatically detecting user presence through key detection and autonomously managing data retention without requiring manual user intervention. The telematics unit itself monitors key status and executes data removal when appropriate, eliminating the need for users to manually clear data while maintaining privacy.
3Object-affected harmful factors
If automatic data removal is implemented when vehicle key is removed, then data privacy is improved, but device complexity is worsened
Solution Approach 1:
The system leverages the existing vehicle key detection capability to automatically trigger data removal operations. By using the key detection mechanism that already exists in the telematics unit, the system avoids adding complex external authentication systems while still achieving automatic data privacy protection through self-service automation.
Solution Approach 2:
The vehicle key serves multiple functions - it not only unlocks the vehicle but also acts as an authentication token that triggers data retention or removal decisions. This multi-functionality allows the system to use existing hardware infrastructure for both vehicle access and data privacy management, reducing overall system complexity.
4Object-affected harmful factors
If personalized data is cleared between users, then data privacy is improved, but service personalization is worsened for the next user
Solution Approach 1:
The system performs preliminary data clearing actions automatically when the vehicle key is removed, ensuring privacy is maintained before the next user accesses the vehicle. When a new user arrives and inserts their key, the system detects this event and reinstates personalized data in advance, ensuring service personalization is restored before the user needs it.
Solution Approach 2:
The system implements periodic data management by clearing personalized data at regular intervals triggered by key removal events and reinstating it when keys are inserted. This periodic cycle of data clearing and restoration ensures that privacy is maintained between users while service personalization is available when needed, creating a rhythmic pattern that balances both requirements.

AI summary
Implementations of the present invention contemplate utilizing the communicative connections between a telematics service provider (TSP), a communication device, and a telematics unit in a vehicle to manage personalized information of a subscriber. Implementations contemplate the removal of personalized information of a subscriber from data stores located at a vehicle, the uploading of personalized information of a subscriber to a database of an operations control center of the TSP, and the downloading of personalized information of a subscriber by a telematics unit of a vehicle from an operations control center of the TSP. Implementations enable personalized information of a subscriber to be removed from a vehicle remotely in order to prevent a user of the vehicle from accessing personalized information of the subscriber. Furthermore, implementations enable personalized information of a subscriber to be accessed by a vehicle in order to provide a subscriber with a customized experience in the vehicle.
