Occupant Authentication System for Vehicle Personalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems face challenges in providing secure and convenient occupant-dependent settings, as they often require manual adjustments and lack efficient authentication methods, leading to potential unauthorized access to personalized data and services.
Innovation Solution
The system incorporates a setting processor, first and second authentication processors, and a server apparatus to authenticate occupants and provide personalized settings, using a combination of biometric and device authentication to ensure secure access to vehicle settings and services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustments are required for vehicle settings, then system simplicity is maintained, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically detecting occupant presence and applying personalized settings before the occupant manually adjusts anything. The setting processor acquires personalized setting data from server memory and automatically configures vehicle parameters based on authenticated occupant profiles, eliminating the need for manual adjustments while maintaining system simplicity through automated preliminary configuration.
2Reliability
If simple authentication methods are used, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The authentication process is segmented into multiple independent stages: first authentication processor handles initial occupant identification, second authentication processor verifies additional credentials, and the setting processor integrates both results. This multi-stage segmentation ensures high reliability through layered verification while maintaining ease of operation by automating each stage sequentially without requiring manual intervention between steps.
3Adaptability or versatility
If personalized setting data is stored on the server, then adaptability is improved, but loss of information increases due to network dependency
Solution Approach 1:
The setting processor acts as an intermediary between the server memory and vehicle systems. It acquires personalized setting data from the server when network connectivity is available, then stores and manages this data locally within the vehicle system. This intermediary approach enables adaptability through cloud-based personalized profiles while preventing information loss by maintaining local caches that function independently when network connectivity is interrupted.

AI summary
An occupant-dependent setting system for a vehicle includes a setting processor, a server apparatus, and first and second authentication processors. The server apparatus includes a server memory that holds personalized setting data regarding an occupant to be on board the vehicle. The first authentication processor authenticates multiple occupants on board the vehicle. The second authentication processor authenticates a combination of the occupants authenticated by the first authentication processor and the vehicle. The setting processor acquires the personalized setting data regarding the occupants authenticated by the second authentication processor, from the server memory of the server apparatus, and provide the vehicle with setting, in accordance with authentication results by the first and second authentication processors with respect to the occupants on board the vehicle.
