Vehicle Swing Door Control Using Learned Opening Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door devices for vehicles do not effectively adjust the opening and closing speed of swing-type doors to suit user preferences, impacting the ease of access and sustainability in transportation systems.
Innovation Solution
A door device equipped with an actuator, controller, and door open/close detector that learns user-preferred opening and closing speeds during manual operations and applies these settings during automatic actions, using a combination of sensors and learning mechanisms to adjust the door's speed based on user location and vehicle tilt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door opening/closing speed is fixed in automatic action, then the control system is simple, but it cannot adapt to user preferences and reduces comfort
Solution Approach 1:
The system performs preliminary learning of user-preferred door speeds during manual operations before applying these settings in automatic mode. The controller stores detected door speeds from manual actions and retrieves them for automatic actions, enabling adaptation without real-time complexity
Solution Approach 2:
The system learns and adapts to user preferences automatically through self-learning during manual operations. The controller autonomously captures door speed data during manual actions and uses this information to adjust automatic door operations, eliminating the need for explicit user programming or complex real-time adjustments
2Productivity
If the door opens/closes quickly, then productivity is improved, but it increases impact on the door and reduces safety for vulnerable users
Solution Approach 1:
The system dynamically adjusts door operation characteristics by learning user preferences and applying appropriate speeds for different scenarios. The controller modifies door speeds based on learned data, enabling fast operations when appropriate and gentle operations when needed, rather than using a fixed speed
Solution Approach 2:
The system changes operational parameters (door speed) based on learned user preferences and detected conditions. The controller stores multiple speed characteristics from manual actions and selects appropriate parameters for automatic actions, optimizing both productivity and safety

AI summary
A door device includes: a door swingable relative to a vehicle body; an actuator configured to drive the door to open and close; a controller configured to perform drive control on the actuator; and a door open/close detector configured to detect an opening/closing speed of the door, wherein the controller is configured to: determine whether an opening/closing action to be performed on the door is a manual action, in which the door is to be manually opened or closed by a user, or an automatic action, in which the door is to be automatically opened or closed by the actuator; and while the manual action is being performed, learn the opening/closing speed detected by the door open/close detector to generate learned value data including information on the opening/closing speed and to reflect the learned value data to the drive control on the actuator while the automatic action is being performed.
