Vehicle Shutdown Authorization via External Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for shutting down illegally used vehicles lack authorization controls, making them susceptible to misuse by unauthorized persons, which can lead to unsafe and unintended shutdowns in critical situations.
Innovation Solution
A system comprising a first control device, a server, and an external authorization system, where the server transmits a shutdown command to the first control device, which requests confirmation from the authorization system, ensuring that only authorized users can initiate the shutdown, and the second control device executes the shutdown, preventing misuse and ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a shutdown command is transmitted without authorization control, then the shutdown function can be easily activated, but the system becomes susceptible to misuse by unauthorized persons
Solution Approach 1:
An external authorization system is introduced as an intermediary between the shutdown command source and the vehicle control device. The authorization system verifies whether the person issuing the shutdown command is authorized before allowing the shutdown to proceed. This mediator resolves the contradiction by adding a security layer without making the shutdown process overly complex for authorized users.
2Reliability
If an external authorization system is introduced, then misuse prevention is improved, but the system complexity increases
Solution Approach 1:
The authorization system is implemented as a separate external unit rather than integrating authorization logic into the vehicle's existing control devices. This approach maintains reliability by isolating the security function while minimizing the complexity impact on the vehicle's core systems. The server communicates with existing control devices through standard protocols, reducing integration complexity.
Solution Approach 2:
The authorization system uses the vehicle's existing communication infrastructure and control devices to execute the shutdown function. Rather than requiring entirely new hardware components, the system leverages available resources such as the vehicle's control units and communication modules, thereby reducing overall system complexity while maintaining security functionality.
3Speed
If the shutdown command is executed without confirmation, then the response time is reduced, but unsafe shutdowns in critical situations may occur
Solution Approach 1:
The system performs preliminary verification of the shutdown command through the external authorization system before executing the shutdown. This preliminary action checks whether the command is authorized and whether current conditions are safe for shutdown, preventing unsafe shutdowns in critical situations while maintaining a relatively fast response time through efficient verification processes.
Data Source
AI summary
A system and a method for shutting down an illegally used vehicle involves a first control device of the vehicle receiving a vehicle shutdown command and a server connected to the first control device and which transmits the vehicle shutdown command to the first control device. The first control device requests confirmation of the vehicle shutdown command in an external authorization system before the shutdown of the vehicle and a second control device initiates the shutdown of the vehicle.
