Vehicle Door Locking via Preliminary Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door opening/closing systems risk incorrectly opening the door when a user attempts to lock it, causing discomfort and inefficiency, especially when loading or unloading baggage.
Innovation Solution
A vehicle door opening/closing apparatus that includes a portable device, a sensing unit for non-contact user presence detection, and an authentication unit to control the door's state (locked or unlocked) based on user intent, preventing incorrect door opening when the door is in a closed and unlocked state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door is in the closed and unlocked state and the sensing unit senses the presence of the user, then the door driving unit drives the door to be in the locked state, but the system must distinguish between user intent to lock versus user intent to open
Solution Approach 1:
The system performs preliminary authentication communication between the portable device and authentication unit before executing the door state change. This preliminary verification step ensures that the user's intent is correctly interpreted and authenticated before the door is locked or opened, preventing incorrect operations while maintaining reliable control.
2Ease of operation
If the door is in the locked state and the sensing unit senses the presence of the user, then the door driving unit drives the door to be in the open state, but the system must ensure the door opens only when intended
Solution Approach 1:
The system uses feedback from the authentication communication between the portable device and authentication unit to determine whether to open the door. The sensing unit detects user presence and triggers authentication, and only after successful authentication does the door driving unit execute the opening action. This feedback mechanism ensures the door opens only when the user intends to do so, improving both convenience and reliability.
3Extent of automation
If the sensing unit uses non-contact detection to sense user presence, then the system can operate without hand contact, but the system must accurately distinguish between loading/unloading baggage and locking intent
Solution Approach 1:
The system performs preliminary authentication communication before executing door state changes. When the sensing unit detects user presence in a non-contact manner, it triggers an authentication sequence that verifies user intent before locking or opening the door. This preliminary verification prevents misinterpretation of user actions during baggage loading/unloading, maintaining high automation while preserving accurate intent detection.

AI summary
A door opening/closing device drives a slide door to a locked state under authentication communication between an authentication ECU of a vehicle side and a mobile device, when the slide door is in a closed and unlocked state and the presence of a user is detected by a detection unit.
