Vehicle Door Closing Control With Camera Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door closing systems fail to accurately prevent passengers from being caught by closing doors when multiple passengers are on board, leading to potential safety issues and unclear reasons for door closure inhibition.
Innovation Solution
A control apparatus that sets a prohibited area near the door, uses an in-vehicle camera to capture images, and displays real-time and still images on a dashboard to inform the driver of passenger presence, allowing for accurate situational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If door closing control is prohibited when a passenger is detected in the predetermined area, then passenger safety is improved, but door closing operation becomes restricted
Solution Approach 1:
The system provides visual feedback to the driver by displaying captured images on a display device when door closing is prohibited. This feedback mechanism allows the driver to understand the reason for prohibition (passenger presence) and take appropriate action, resolving the contradiction by maintaining safety while improving operational clarity
Solution Approach 2:
The control apparatus acts as an intermediary between the door closing system and the driver. It mediates the door closing operation by detecting passenger presence, prohibiting closing when necessary, and providing visual information to the driver, thus balancing safety requirements with operational needs
2Loss of information
If real-time image display is provided to show passenger presence, then driver awareness is improved, but information clarity becomes insufficient without historical context
Solution Approach 1:
The system captures and stores images at the moment door closing is prohibited, preserving historical information about passenger presence. This preliminary action of capturing evidence allows the driver to review what happened at the critical moment, improving both awareness and accuracy of situational understanding
Solution Approach 2:
The display shows multiple images segmented in time - the current real-time image and the captured image from when closing was prohibited. This segmentation of temporal information allows the driver to compare different moments and understand the sequence of events, enhancing overall situational awareness

AI summary
If it is detected that a passenger is present in the predetermined area set near the door inside the vehicle while the door is in open state, a control apparatus prohibits door closing control. The control apparatus displays, when a close button is pressed by a driver while the door closing control is prohibited, image captured by an in-vehicle camera at the timing when the close button is pressed, on a display for a predetermined period of time, together with real-time image of the inside of the vehicle captured by the in-vehicle camera in a divided manner.
