Autonomous Vehicle Two-Stage Authentication Before Departure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving vehicles may start unintentionally without a user's intention, leading to discomfort and reliability issues in driverless transportation services, as they can operate without ensuring the user's presence or authorization.
Innovation Solution
Implementing a two-stage authentication process for the autonomous driving vehicle, where first authentication occurs outside the vehicle before unlocking the door and second authentication inside the vehicle cabin, ensuring only authorized users can initiate the vehicle's start.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the autonomous driving vehicle operates without authentication, then the ease of operation is improved, but the reliability deteriorates due to unauthorized starts
Solution Approach 1:
The authentication process is divided into two distinct stages: first authentication performed outside the vehicle before door unlocking, and second authentication performed inside the vehicle before departure. This segmentation ensures that even if one authentication stage is compromised, the vehicle cannot be operated unauthorizedly, thus maintaining reliability while preserving ease of operation through automated processes.
Solution Approach 2:
The system performs first authentication as a preliminary action before the door is unlocked and before the vehicle can be operated. This preliminary verification of user identity prevents unauthorized individuals from accessing or starting the vehicle, thereby ensuring reliability before the ease of operation is engaged.
2Device complexity
If single-stage authentication is used, then the device complexity is reduced, but the reliability deteriorates due to insufficient user verification
Solution Approach 1:
The authentication system is segmented into two independent authentication stages with different verification methods. First authentication occurs outside the vehicle using one method, and second authentication occurs inside the vehicle using a different method. This segmentation provides robust verification without requiring overly complex single-stage systems, balancing device complexity with enhanced reliability.
Solution Approach 2:
The control device acts as an intermediary that coordinates between the two authentication stages, the door lock system, and the departure control. It manages the sequential authentication process and ensures that each stage is properly verified before proceeding to the next, maintaining system reliability without excessive complexity.
3Productivity
If the vehicle starts without confirming user presence, then the productivity is improved, but the object-affected harmful factors increase due to unauthorized operation
Solution Approach 1:
The system applies preliminary anti-action by performing second authentication inside the vehicle as a countermeasure before allowing departure. This internal verification ensures that the authorized user is actually present inside the vehicle before it starts moving, preventing harmful unauthorized operation while maintaining productivity through efficient automated verification.
Solution Approach 2:
The authentication system provides feedback loops where the control device verifies authentication results at each stage and only proceeds to the next stage or allows departure when verification is successful. This feedback mechanism ensures that unauthorized operation is prevented while maintaining efficient vehicle operation when authentication is proper.

AI summary
When an autonomous driving vehicle picks a user up, a control device performs departure condition confirmation processing. The departure condition confirmation processing includes first authentication processing that performs authentication of the user outside the autonomous driving vehicle based on first authentication information, door lock release processing that releases a door lock in response to the completion of the first authentication processing, second authentication information provision processing that makes the user acquire second authentication information different from the first authentication information in response to the completion of the first authentication processing, second authentication processing that performs authentication of the user inside a vehicle cabin of the autonomous driving vehicle based on the second authentication information, and start permission processing that permits the start of the autonomous driving vehicle in a case where the second authentication processing is completed.
