Vehicle Door Swipe Unlock Control for Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door control systems often release the door lock unintentionally due to contact with the door grip, lacking clear user intention detection, leading to unnecessary door opening.
Innovation Solution
A vehicle door control device featuring a swipe operation portion with multiple electrostatic capacitance sensors and a controller that detects intentional swipe operations to release the door lock, ensuring the door only opens with deliberate user intent, utilizing a continuous swipe operation portion integrated with the door assist grip for intuitive operation guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single sensor electrode is disposed on the door grip to detect contact, then the door can be opened by simple contact, but the door lock is released unintentionally even when the user touches the door grip without intention to open
Solution Approach 1:
The door grip is divided into multiple sensor regions (first sensor region and second sensor region) along the swipe direction. By segmenting the detection area, the system can distinguish between a deliberate swipe operation (activating sensors in sequence) and accidental contact (activating only one sensor), thereby resolving the contradiction between ease of operation and reliable intention detection.
2Extent of automation
If contact detection is used for door lock release, then the operation is simple and conscious operation is not necessary, but the door opens unnecessarily due to unintentional contact
Solution Approach 1:
The control unit monitors the sequence and timing of sensor activations as feedback. By analyzing whether the first and second sensors are activated in a specific temporal sequence corresponding to a swipe motion, the system can automatically determine intentional operation while maintaining automated door opening functionality, thus resolving the contradiction between automation extent and reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system accurately reflects user operation intentions, preventing unintended door openings by requiring a specific swipe motion, ensuring the door remains closed unless intentionally opened, enhancing user experience and operational clarity.
Implementation Method 1
a detection unit provided at least in the swipe operation portion and configured to detect a swipe operation
Data Source
AI summary
A vehicle door control device includes a swipe operation portion provided on a vehicle interior side of a door, a detection unit provided at least in the swipe operation portion and configured to detect a swipe operation, a door lock device configured to hold the door in a closed state, and a controller configured to release a closed state of the door by the door lock device when it is determined that the swipe operation is detected based on a detection result of the detection unit.
