Vehicle Scrapping Verification for eCall Termination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing emergency call (eCall) system fails to safely terminate when a vehicle is scrapped, leading to uncancelled communication terminals and potential malfunctions, as the vehicle-scrapping information is not properly notified, causing issues with ICCID revocation and airbag system malfunctions.
Innovation Solution
A device and method for verifying vehicle-scrapping information that includes a communication terminal receiving scrapping instructions to enter a scrapping mode and transmit end-of-use information to a management server, while the airbag controller generates and transmits an airbag deployment signal, ignoring interrupt signals and using a call scenario to securely terminate the eCall system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the eCall system is maintained in the opened state forever without scrapping information, then the communication terminal remains active indefinitely, but this causes problems for uncancelled communication terminals and potential security issues
Solution Approach 1:
The system performs preliminary actions by detecting scrapping information before the eCall system needs to be terminated. The control unit detects scrapping information of the vehicle in advance, determines that scrapping has occurred, and then automatically transmits termination requests to the management server, ensuring proper termination before any potential security issues arise.
Solution Approach 2:
The system establishes a feedback loop where the control unit continuously monitors for scrapping information, processes this information to determine vehicle scrapping status, and automatically responds by transmitting termination requests. This closed-loop feedback mechanism ensures the eCall system is properly terminated when scrapping occurs, resolving the contradiction between continuous operation and secure termination.
2Reliability
If the vehicle manufacturer notifies every ICCID of the relevant eCall to a communication company for cancellation, then the eCall can be revoked, but this process is complex and requires manual intervention from both manufacturer and communication company
Solution Approach 1:
The control unit in the vehicle's eCall system performs self-service by automatically detecting scrapping information, determining vehicle scrapping status, and transmitting termination requests to the management server without requiring manual intervention from manufacturers or communication companies. This automation eliminates the complex multi-party notification process while ensuring complete eCall revocation.
Solution Approach 2:
The management server acts as an intermediary between the vehicle's control unit and the communication company. The control unit transmits termination requests to the management server, which then handles the ICCID cancellation with the communication company, simplifying the process for the vehicle manufacturer while ensuring complete revocation.
3Reliability
If scrapping information is not properly verified, then the eCall system cannot be terminated safely, but implementing verification requires additional detection and processing mechanisms
Solution Approach 1:
The control unit performs multiple functions: it detects scrapping information, determines vehicle scrapping status, and transmits termination requests. This multi-functional approach consolidates the verification mechanism within an existing component, achieving safe termination without adding significant complexity to the system.

AI summary
A device for verifying vehicle-scrapping information may include a communication terminal configured to receive scrapping instruction from a diagnostor to enter a scrapping mode, and transmit end-of-use information according to the scrapping instruction to a management server, and an airbag controller configured to receive the scrapping instruction from the diagnostor and transmit an airbag deployment signal to the communication terminal, wherein the communication terminal ignores all interrupt signals when entering the scrapping mode.
