Vehicle Door Access Control Using Multi-Image User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle systems struggle to efficiently control openable and closeable objects such as doors based on the proximity and authentication of a user, often leading to unnecessary operations and hindering ease of entry and exit.
Innovation Solution
A vehicle control apparatus that includes an approach detection section, authentication section, and openable and closeable object operation control section to detect and authenticate a user through multiple image captures, ensuring appropriate operation of vehicle doors when the user is confirmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle system operates the openable and closeable object when a person is detected near the vehicle, then the ease of getting in and out of the vehicle is improved, but unnecessary door operations occur when the detected person is not the user
Solution Approach 1:
The system performs preliminary authentication checks by capturing multiple images and verifying user identity before operating the door. The authentication section captures a first image when a person approaches, determines authentication result, and only proceeds to door operation if authentication succeeds, preventing unnecessary operations
Solution Approach 2:
The system implements feedback mechanisms by capturing additional images based on authentication results. When authentication fails or is inconclusive, the system captures a second image for re-evaluation, and continues capturing images until authentication is confirmed or rejected, ensuring reliable user verification before door operation
2Reliability
If the system performs multiple image captures and authentication checks, then the accuracy of user authentication is improved, but the time required for door operation increases
Solution Approach 1:
The system performs preliminary authentication with a first image capture before committing to door operation. This preliminary check allows the system to quickly reject non-users early in the process, avoiding unnecessary time consumption for users who will ultimately gain access
Solution Approach 2:
The authentication process is made dynamic by adaptively determining whether to capture additional images based on the result of the first authentication. The control section decides in real-time whether a second image capture is necessary, optimizing the balance between authentication reliability and time efficiency
3Reliability
If the system continuously monitors and captures images of people near the vehicle, then the security and accuracy of user identification is improved, but the energy consumption of the image capturing unit increases
Solution Approach 1:
The system uses periodic action by capturing images at specific intervals and conditions rather than continuously. The image capturing unit is activated when a person approaches the vehicle, performs authentication captures, and stops when authentication is complete, reducing energy consumption while maintaining security
Solution Approach 2:
The system performs preliminary detection to determine if a person is present before activating the image capturing unit for full authentication. This preliminary check allows the system to avoid unnecessary image capture operations when no user is present, conserving energy while maintaining readiness for authentication

AI summary
A vehicle control apparatus includes: an approach detection section detects a person around a vehicle; a start control section starts an image capturing unit mounted on the vehicle when the approach detection section detects a person; an authentication section authenticates the person detected as a user of the vehicle by using an image captured and decide authentication completion under a condition that the authentication is established an authentication criterion number of times or more; and an openable and closeable object operation control section brings an openable and closeable object operation unit into operation when the authentication section decides authentication completion. The openable and closeable object operation unit performs at least one of releasing a lock of an openable and closeable object and executing an opening operation of opening the openable and closeable object included in the vehicle.
