Vehicular Authentication Device Parallel Processing Steering Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular authentication systems that use biometric information as driving intent take longer to activate the vehicle since biometric authentication processing is sequential with steering lock release, leading to delayed engine activation.
Innovation Solution
A vehicular authentication device with two processors that allows parallel processing of steering lock release and biometric verification, enabling the vehicle to be placed in an activation-enabled state more quickly by permitting steering lock release upon successful key information verification and subsequent immobilizer deactivation upon successful biometric authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication processing is performed sequentially before steering lock release, then authentication security is improved, but vehicle activation time increases
Solution Approach 1:
The system performs preliminary key information verification through the first processor before biometric authentication, enabling the steering lock to be released in advance. This preliminary action allows the vehicle to enter an activation-enabled state earlier, reducing overall activation time while maintaining security through the sequential biometric verification step that follows.
Solution Approach 2:
The authentication system is divided into two independent processing segments: the first processor handles key information verification and steering lock release, while the second processor handles biometric authentication and immobilizer deactivation. This segmentation allows parallel execution of authentication tasks, reducing total activation time while maintaining security through layered verification.
2Reliability
If biometric authentication is performed before steering lock release, then security verification is improved, but processing speed deteriorates
Solution Approach 1:
The verification process is segmented into two parallel tracks: key information verification by the first processor that enables steering lock release, and biometric verification by the second processor that controls immobilizer deactivation. This segmentation allows both security checks to proceed simultaneously, improving processing speed while maintaining rigorous security verification.
Solution Approach 2:
Key information verification is performed as a preliminary action that enables steering lock release before biometric authentication completes. This preliminary verification establishes initial security while allowing the vehicle system to prepare for activation, improving overall processing speed without compromising security verification integrity.

AI summary
A vehicular authentication device that includes: a first processor; and a second processor. The first processor is configured to: perform a first permission to permit release of a steering lock of a vehicle in a case in which a verification of key information of the vehicle has been performed successfully, and in a case in which the steering lock has been released by the first permission, perform a second permission to permit deactivation of an immobilizer of the vehicle based on a successful verification of biometric information by the second processor.
