Vehicle Power Supply Mode Authentication Against Unauthorized Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles that supply power to external facilities lack security measures when passengers leave the vehicle, potentially leading to unauthorized power usage or theft.
Innovation Solution
Implementing a processor-controlled power supply mode in vehicles that requires authentication information input for mode cancellation, ensuring secure power supply by integrating a vehicle control device with authentication mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle supplies power to external facilities without authentication requirements, then power supply convenience is improved, but security against unauthorized use deteriorates
Solution Approach 1:
The system performs preliminary authentication verification before allowing power supply mode cancellation. When a cancel request is detected, the system first checks for valid authentication information (biometric data, IC card, or password) before permitting the mode change. This preliminary security check ensures that only authorized users can cancel the power supply mode, preventing unauthorized use while maintaining operational convenience for legitimate users.
2Reliability
If authentication mechanisms are added to the power supply system, then security is improved, but device complexity increases
Solution Approach 1:
The vehicle control device integrates multiple authentication functions (biometric authentication, IC card authentication, and password authentication) into a single unified system. The processor evaluates different types of authentication information using the same fundamental verification process, allowing the system to provide comprehensive security through one multi-functional component rather than requiring separate dedicated systems for each authentication method.
Solution Approach 2:
The system utilizes existing vehicle components and data storage capabilities to provide authentication functions. The vehicle control device leverages the vehicle's own processor, memory, and existing sensor systems (for biometric data) to perform authentication, rather than requiring entirely external authentication systems. This self-service approach enhances security while minimizing the addition of external complex components.
3Reliability
If the vehicle requires authentication for power supply mode cancellation, then unauthorized use is prevented, but operation time increases
Solution Approach 1:
The authentication requirement is applied periodically and selectively rather than continuously. The system monitors for cancel requests and only triggers authentication at these specific moments when mode cancellation is attempted. During normal power supply operation, no authentication is required, allowing the system to maintain strong security controls while minimizing the frequency and impact of authentication interruptions on overall operation time.

AI summary
The information processing device includes a processor configured to control setting and cancellation of a power supply mode in which the power supply device operates, for a vehicle including the power supply device that supplies electric power to the outside. The processor outputs information requesting an input of authentication information when a canceling request of the power supply mode that is set is acquired.
