Vehicle Component Anti-Theft Release for Resale and Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft functions for vehicle components prevent their resale or reuse, causing economic loss and limiting the flexibility of motor vehicle owners.
Innovation Solution
A control device that can detect and deactivate the anti-theft function of a vehicle component by recognizing pre-defined events, such as reaching a certain mileage or age, allowing for the decoupling of cryptographic keys or resetting via tokens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an anti-theft function is activated in a vehicle component, then theft protection is improved, but the ability to resell or reuse the component is worsened
Solution Approach 1:
The anti-theft function is made dynamically controllable rather than permanently fixed. The control device can change the state of the cryptographic coupling between the vehicle component and the motor vehicle, switching between activated and deactivated states based on predetermined events, allowing the component to be adapted for resale or reuse when needed
Solution Approach 2:
The system changes the parameter of cryptographic key coupling status. By modifying whether the cryptographic keys are coupled or decoupled between the vehicle component and the motor vehicle, the system transitions the component between protected and reusable states, enabling resale capability while maintaining theft protection when required
2Reliability
If an anti-theft function is activated in a vehicle component, then security against unauthorized use is improved, but economic flexibility is worsened
Solution Approach 1:
The system performs preliminary actions by establishing cryptographic coupling before theft can occur, and by pre-configuring the control device to automatically deactivate the anti-theft function when predetermined events occur. This preliminary setup ensures both security during use and automatic economic flexibility when resale is needed
Solution Approach 2:
The control device continuously monitors for predetermined events (such as resale conditions or component removal) and provides feedback by automatically deactivating the anti-theft function when these events are detected. This feedback mechanism maintains security during normal operation while automatically enabling economic flexibility when appropriate conditions are met
3Reliability
If cryptographic coupling is established between vehicle component and motor vehicle, then anti-theft protection is improved, but component reusability is worsened
Solution Approach 1:
The cryptographic coupling is implemented as a dynamic rather than permanent bond. The control device can decouple the cryptographic keys when predetermined events occur, allowing the vehicle component to be transferred to new ownership or reused in different applications, thereby extending its service life while maintaining protection during each ownership period

AI summary
A control device configured to deactivate an activated anti-theft function of a vehicle component of a motor vehicle is provided. The control device determines whether a previously determined event has occurred and, in such a case, deactivates the activated anti-theft function of the vehicle component.
