Vehicle Door Gesture Detection for Remote Opening Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door control systems in vehicles require users to physically approach the vehicle to open the rear door, limiting convenience for quick boarding.
Innovation Solution
A gesture detection device and method that uses a camera to detect predefined hand gestures made by a user facing the vehicle's side surface, determining the user's position and gesture through machine learning, and controlling door operations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a distance sensor is used to detect hand movement near the door handle, then the door can be opened quickly by hand movement, but the user must physically approach the vehicle to use this function
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture images of the user from a distance. The image processing unit then analyzes these images to detect gestures and determine user intent, enabling door control without requiring the user to physically approach the vehicle handle area
Solution Approach 2:
The patent replaces the mechanical proximity-based hand detection system with an optical imaging and image processing system. Instead of using a distance sensor to detect physical hand movement near the door, the system uses camera imaging combined with AI-based gesture recognition to detect and interpret user intentions from a distance
2Adaptability or versatility
If gesture detection is implemented using camera imaging, then user proximity is not required, but the system complexity increases due to image processing requirements
Solution Approach 1:
The patent integrates multiple functions into a single image processing unit that can perform gesture detection, user identification, and intent recognition all through image analysis. This multi-functional approach consolidates what could be separate complex systems into one integrated unit, managing system complexity while providing versatile remote control capabilities

AI summary
A gesture detection device (70) includes a position acquisition unit (73) configured to acquire a predetermined position that is a position of a body part of a user in an image captured by a camera (50) and a reference position, a direction determination unit (74) configured to determine whether the user faces an opening portion of a vehicle (10), and a gesture determination unit (75) configured to determine whether the user has made a gesture. The gesture determination unit (75) determines that the user has made a predetermined gesture for opening at least a door when the predetermined position is moved relative to the reference position in a predetermined direction corresponding to an opening direction of the door.
