Vehicle Door Opening Restriction Control for Safety and Convenience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle door apparatuses restrict door opening when detecting moving objects, but this can lead to inconvenience when multiple vehicles pass by, requiring occupants to force the door open, indicating a need for improved safety and convenience.
Innovation Solution
A vehicle door apparatus with a moving object detector, door opening operation detector, and door opening safety control unit that restricts door opening when a moving object is detected but permits opening after a predetermined number of safe door operation attempts, ensuring safety while allowing convenient access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If door opening restriction is performed when detecting moving objects, then safety is improved, but door opening convenience deteriorates
Solution Approach 1:
The door opening restriction control is made dynamic by allowing it to be canceled when a door opening operation is detected a predetermined number of times. This transforms the static restriction into a dynamic control that adapts to occupant intent, resolving the contradiction between safety and convenience.
Solution Approach 2:
The system uses feedback from detecting door opening operations to determine whether to cancel the restriction. By counting the number of detection operations and comparing against a predetermined threshold, the system receives feedback about occupant intent and adjusts the restriction accordingly, balancing safety with operational convenience.
2Reliability
If door opening restriction is maintained when multiple vehicles pass by, then safety is improved, but productivity deteriorates
Solution Approach 1:
The restriction control dynamically adapts to the situation by canceling when the detection operation count reaches a predetermined number. This allows the system to maintain safety during normal operation while enabling efficient door opening when the occupant genuinely needs to exit, even when vehicles are passing by.
Solution Approach 2:
The system changes the control parameter (restriction status) based on the detection operation count. When the count reaches the predetermined threshold, the parameter changes from restricted to permitted, optimizing both safety and productivity based on the current operational context.

AI summary
A vehicle door apparatus includes: a moving object detector configured to detect a moving object approaching a door of a vehicle; a door opening operation detector configured to detect a door opening operation performed by an occupant in the vehicle; a door opening restriction unit configured to restrict opening of the door by the door opening operation when detecting approach of the moving object; and a door opening permission unit configured to permit opening of the door by the door opening operation when the door opening operation is detected a predetermined number of times in a state in which the opening of the door is restricted.
