On-vehicle Authentication Apparatus for Collaborative Key Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle authentication methods, such as using headlamp turns or horn sounds, are ineffective in preventing clandestine thefts, especially in daylight or noisy environments, as they can be inconspicuous or annoying, leading to security vulnerabilities.
Innovation Solution
An on-vehicle authentication apparatus that acquires information on vehicle operations and determines if a collaborative operation involving multiple operating members has been performed, allowing for the registration or invalidation of electronic keys only when specific, multi-part manipulations are executed, such as simultaneous actions inside and outside the vehicle, enhancing security through complex authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods (headlamp turns or horn sounds) are used, then the authentication process can be executed, but the security effectiveness deteriorates in daylight or noisy environments as these operations become inconspicuous or drowned out
Solution Approach 1:
The authentication process is divided into multiple independent operation steps that must be completed in sequence. Instead of relying on a single conspicuous action like headlamp turns or horn sounds, the system segments authentication into several distinct operations (e.g., opening door, starting engine, pressing brake) that together form a unique authentication sequence, making it harder for thieves to perform clandestine thefts.
Solution Approach 2:
The system dynamically adapts the authentication requirements based on the vehicle state and operational context. The authentication process evolves through multiple stages where each completed operation triggers the next required operation, creating a dynamic authentication flow that responds to the vehicle's actual state rather than relying on static, predictable signals.
2Ease of operation
If conventional authentication methods (headlamp turns or horn sounds) are used, then the authentication process can be executed, but the annoyance to surroundings increases, especially in noisy environments or during daytime
Solution Approach 1:
The system replaces acoustic and optical authentication signals (horn sounds and headlamp turns) with mechanical operation-based authentication. Instead of requiring the vehicle to produce audible or visible signals, the system detects mechanical operations performed on the vehicle (door opening, engine starting, brake pressing), eliminating the need for noisy or light-intensive authentication methods.
3Ease of operation
If simple authentication operations are used, then the ease of operation is improved, but the security against clandestine theft deteriorates
Solution Approach 1:
The authentication process is divided into multiple independent operation steps that must be completed in sequence. Instead of relying on a single conspicuous action like headlamp turns or horn sounds, the system segments authentication into several distinct operations (e.g., opening door, starting engine, pressing brake) that together form a unique authentication sequence, making it harder for thieves to perform clandestine thefts.
Solution Approach 2:
The system employs periodic authentication checks where multiple operations must be performed in a specific sequence within a predetermined time window. This periodic nature of the authentication process, requiring repeated specific actions in order, creates a rhythm that is difficult for thieves to replicate quickly or clandestinely.

AI summary
A vehicle authentication apparatus including an acquisition unit (65D) configured to acquire information indicating a content of a manipulation on a vehicle from a detection unit mounted on the vehicle; a manipulation determination unit (65E) configured to determine whether a predetermined collaborative manipulation executable by two or more manipulators is performed on the basis of information acquired by the acquisition unit; and an execution unit (65F, 65H) configured to execute a registration process of registering an electronic key of the vehicle in the on-vehicle authentication apparatus or an invalidation process of invalidating the electronic key registered in the on-vehicle authentication apparatus, in a case that it is determined by the manipulation determination unit that the collaborative manipulation is performed.
