Vehicle Door Control Using Authentication and Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door control systems require pre-registration of automatic opening and closing instructions on a mobile device, leading to poor usability.
Innovation Solution
A vehicle door control apparatus that allows door opening and closing operations without special mobile device operations by using a detection unit to determine if a user is within a predetermined area and authenticating the user's ID information, enabling automatic door control based on natural user motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-registration of automatic opening and closing instructions is required on a mobile device, then door control reliability is improved through authentication, but usability deteriorates due to complex operations
Solution Approach 1:
The system performs preliminary authentication of the mobile device and pre-registers the user as an authorized person in advance. This preliminary action stores authentication results and user status in the door control device, eliminating the need for repeated registration operations during actual door opening/closing usage.
Solution Approach 2:
The door control device automatically manages authentication and user registration without requiring manual intervention during door operations. The system self-updates the authorized persons list based on authentication results, and automatically determines whether to open/close doors based on detected object positions and authorized user status.
2Ease of operation
If automatic door opening is enabled based on object detection, then convenience is improved, but safety deteriorates due to potential accidental openings during vehicle operation
Solution Approach 1:
The door control device dynamically adjusts its behavior based on real-time conditions. When the vehicle is determined to be in operation (engine running, gear engaged), the system disables automatic door opening even if objects are detected in the determination area. When the vehicle is stopped and authenticated users are present, automatic opening is enabled. This dynamic adaptation resolves the contradiction between convenience and safety.
Solution Approach 2:
The system continuously monitors vehicle operation status through feedback from the vehicle's control unit and authenticated user status. Based on this feedback, the door control device intelligently determines whether to permit automatic door opening, preventing accidental openings during vehicle operation while maintaining convenience when appropriate.

AI summary
A door (3) for closing an opening of a vehicle is operated to close by treating an authentication validation to an ID information outputted from a mobile device (2) carried by a user in an authentication unit (1) as a necessary condition. A detection of an object (4) being separated from a predetermined determination area (R) adjacent to the door (3) after continuously located in the determination area (R) over a predetermined time is added to a necessary condition for the opening operation of the door (3).
