Vehicle Control System Dual Authentication Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems fail to ensure that vehicle maintenance can be performed quickly and only by authorized personnel, leading to potential delays in addressing vehicle failures, as unauthorized maintenance operators can gain access when not needed, and necessary maintenance is hindered without manager approval.
Innovation Solution
A vehicle control system that requires dual authentication processes for both maintenance operators and managers to authorize vehicle maintenance, ensuring that only authenticated individuals can perform operations, preventing unintended maintenance and allowing for emergency measures within limited permission ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a maintenance operator with an electronic key approaches the vehicle, then vehicle maintenance operation is permitted through normal authentication, but unauthorized maintenance operators can gain access when maintenance is not needed
Solution Approach 1:
The authentication system is segmented into two independent authentication processes: first authentication for the maintenance operator and second authentication for the vehicle owner. This segmentation ensures that both parties must independently verify each other's identity, preventing unauthorized access while maintaining ease of operation for legitimate maintenance scenarios
Solution Approach 2:
The vehicle's authentication unit acts as an intermediary that mediates between the maintenance operator and the vehicle owner. It requires mutual authentication through registered authentication information before permitting maintenance operations, thus ensuring security without significantly complicating the access process for authorized personnel
2Reliability
If approval from the manager is required for vehicle maintenance, then unauthorized maintenance is prevented, but necessary maintenance cannot be performed quickly
Solution Approach 1:
Authentication information for both the maintenance operator and the vehicle owner is registered in advance in the vehicle's authentication unit. When maintenance is needed, the pre-registered authentication information is immediately verified through the dual authentication process, eliminating the need for real-time manager approval while maintaining security
Solution Approach 2:
The system provides immediate feedback through the authentication process: if both the maintenance operator and vehicle owner are properly authenticated, maintenance permission is granted instantly. This feedback mechanism ensures security while avoiding time delays, as the decision is made automatically based on pre-registered credentials rather than requiring sequential human approval
Data Source
AI summary
A first authentication process unit and a second authentication process unit of an ECU constituting a system respectively perform a first authentication process and a second authentication process for comparing authentication information acquired from a maintenance operator terminal and a user terminal, and first authentication information of a first authentication information registration unit and second authentication information of a second authentication information registration unit. An authority setting unit performs an operation permission for a vehicle for the purpose of maintaining the vehicle when the authentications match.
