Vehicle Controller Data Deletion via Bus-Wide Reset Command
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods require a workshop visit to reset user-specific and drive-specific data in a motor vehicle, which lacks user control and convenience, especially in light of data protection regulations like GDPR.
Innovation Solution
A method and system that allow users to control the deletion of user-specific and drive-specific data distributed across multiple controllers in a motor vehicle, using a trigger apparatus that sends a common delete command via a data bus, ensuring all controllers reset to a factory state without the need for a workshop visit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a workshop visit is used to reset user data in all controllers, then complete data deletion is achieved, but user convenience and control are lost
Solution Approach 1:
The system enables users to independently trigger the delete command through the trigger apparatus using simple operations (e.g., pressing a button or selecting a menu item). The trigger apparatus autonomously transmits the command via the data bus to all controllers, which automatically execute their delete routines without requiring workshop intervention, thus achieving complete data deletion while maintaining user convenience
Solution Approach 2:
The system divides the data deletion function across multiple independent controllers, each with its own delete routine. Instead of requiring centralized workshop resetting of all controllers simultaneously, each controller independently processes the delete command received via the data bus, ensuring complete data deletion across the distributed system while enabling user-initiated operation
2Ease of operation
If individual controller data resetting is performed, then user control is improved, but complete data deletion across all controllers is not achieved
Solution Approach 1:
The trigger apparatus serves multiple functions: it detects user-triggered conditions, generates the delete command, and transmits it via the data bus to all controllers in the system. This universal trigger mechanism ensures that a single user action propagates the delete command system-wide, achieving both user control and complete data deletion across all controllers simultaneously
Solution Approach 2:
The system implements acknowledgment mechanisms where controllers confirm receipt and execution of the delete command. This feedback loop ensures that the user-initiated delete operation is reliably transmitted to and executed by all controllers, verifying complete data deletion while maintaining user control over the process
3Adaptability or versatility
If decentralized data storage is used in controllers, then system flexibility is improved, but data protection and user control become more difficult
Solution Approach 1:
The trigger apparatus acts as an intermediary that bridges the user and the distributed controllers. It receives user-triggered conditions, formulates the delete command, and transmits it through the data bus to all controllers. This intermediary simplifies data protection by providing a centralized control point for initiating deletion across the decentralized system, reducing user burden while maintaining system flexibility
Solution Approach 2:
The system dynamically adapts to user needs by allowing the trigger condition to be flexibly configured (e.g., button press, menu selection, time-based triggers). The trigger apparatus can respond to different user actions and system states, enabling users to initiate data deletion at convenient times through various input methods, thus simplifying data protection in decentralized systems
Data Source
AI summary
The invention relates to a method for removing user-specific and/or drive-specific user data which are saved distributedly on multiple controllers in a motor vehicle. A trigger apparatus is provided, and the trigger apparatus checks whether a trigger condition has been satisfied. If the trigger condition has been satisfied, a specified common delete command is transmitted to the plurality of controllers of the motor vehicle via a data bus of the motor vehicle, and each controller carries out a specified delete routine if the controller has received the delete command from the data bus, said delete routine being used to overwrite and/or delete user data saved on the particular controller.
