Vehicle Door Control Proximity Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems for keyless entry systems struggle to accurately determine when to start and stop the door closing operation based on the distance between the portable terminal and the vehicle, leading to potential user inconvenience and safety issues.
Innovation Solution
A vehicle control apparatus that includes an actuator, a reservation part, a storage part, a portable terminal, a communication apparatus, and a controller, which starts the door closing operation when the distance between the communication apparatus and the portable terminal is within a first predetermined range and stops it when within a second adjacent range, allowing for precise control based on user proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the door closing operation is started based on reservation information when the portable terminal is within range, then the door can be closed automatically without manual intervention, but the closing operation continues regardless of user presence changes, which may be against user intention or unsafe
Solution Approach 1:
The system continuously monitors the distance between the portable terminal and the vehicle during the door closing operation. When the terminal enters the second predetermined range (closer to the vehicle), the system receives feedback indicating user presence and automatically stops the closing operation, ensuring alignment with user intention.
Solution Approach 2:
The door closing operation is designed to be dynamic rather than static. The operation can be started automatically when the terminal is in the first range and stopped dynamically when the terminal enters the second range, allowing the system to adapt to changing user presence conditions during the closing process.
2Ease of operation
If the door closing operation is started based on reservation information, then the user does not need to manually operate the door, but the user cannot confirm whether the closing operation is completed safely
Solution Approach 1:
The system provides feedback to the user through continuous distance monitoring. When the portable terminal enters the second predetermined range during the closing operation, the system stops the closing and notifies the user, allowing confirmation of the closing status before completion.
3Device complexity
If a single predetermined distance range is used for starting the door closing operation, then the control logic is simple, but the system cannot distinguish between user intentions to stop or confirm the closing operation
Solution Approach 1:
The single distance range is segmented into two distinct predetermined ranges: the first range for starting the door closing operation and the second (adjacent) range for stopping the operation. This segmentation allows the system to distinguish between different user intentions based on the terminal's position.
Solution Approach 2:
Different control actions are assigned to different spatial zones. The first predetermined range triggers door closing, while the second adjacent range triggers door stopping. This local differentiation of control responses based on position enables precise interpretation of user intention.

AI summary
A vehicle control apparatus is disclosed, which includes an actuator that is provided on a vehicle and performs a door closing operation of the vehicle; a reservation part; a storage part that stores reservation information; a portable terminal; a communication apparatus that is provided on a vehicle to bi-directionally communicate with the portable terminal; and a controller that causes, when the reservation information is stored in the storage part, the actuator to start the door closing operation when a distance between the communication apparatus and the portable terminal is within a first predetermined range, and causes, during the door closing operation of the door, the actuator to stop the door closing operation when the distance is within a second predetermined range that is adjacent to the first predetermined range.
