Vehicle Door Control Device for Valet Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door control systems in vehicles fail to efficiently open only the necessary doors during automatic valet parking, leading to security concerns and reduced convenience due to unnecessary door openings and increased operational burden on occupants.
Innovation Solution
A door control device that includes a seating position detector and a door controller, which determines the appropriate door to open based on seating information and proximity, using a door driver to automate the opening process while ensuring security and convenience by limiting door openings to only necessary doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all doors are opened automatically during valet parking, then convenience for occupants is improved, but security is compromised and unnecessary door openings occur
Solution Approach 1:
The patent applies local quality by determining which specific door to open based on the seating position of the occupant. Instead of opening all doors uniformly, the system selectively opens only the door corresponding to the detected seating position, thereby providing convenience while maintaining security by limiting door openings to what is necessary.
2Extent of automation
If door opening is automated without seating detection, then operational burden is reduced, but unnecessary doors may open reducing efficiency
Solution Approach 1:
The patent implements feedback by using the seating position detector to provide information about occupant location to the door controller. This feedback loop enables the automated system to make intelligent decisions about which door to open, combining high automation with improved efficiency by avoiding unnecessary door openings.
3Measurement precision
If seating position detection is added to determine which door to open, then door opening precision is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by having the seating position detector automatically identify the occupant's location and the door controller automatically determine and open the appropriate door without requiring manual input from the occupant. This automation of the selection process improves precision while managing complexity through integrated detection and control functions.
Data Source
AI summary
A door control device in a vehicle including seats and doors, includes: a door driver; a seating position detector; and a door controller. The door driver at least drives opening of the doors. The seating position detector detects a seating position information indicating a position of the seat on which an occupant is seated. The door controller determines a door to be opened on the basis of the seating position information detected by the seating position detector and causes the door driver to drive opening of the determined door.
