Vehicle Door Closing Control Using Two-Area Key Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door control systems may initiate unintended closing operations if a communication terminal, such as an electronic key, momentarily moves out of the determination area, causing user discomfort.
Innovation Solution
A vehicle control device that acquires determination results for two areas outside the vehicle cabin: a first area and a second area further away. The control section then performs a closing operation based on the determination results for both areas, ensuring the door only closes when the communication terminal is consistently outside both areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the door control device initiates closing operation when the communication terminal moves out of the determination area, then the door closing operation can be performed, but unintentional closing operations may occur causing user discomfort
Solution Approach 1:
The system performs preliminary detection by monitoring whether the communication terminal has moved out of the determination area before initiating the closing operation. This preliminary check ensures that the closing operation is only started when the terminal is consistently outside the area, preventing unintentional closures while maintaining efficient door operation.
2Reliability
If the door control device waits for the communication terminal to be consistently outside the determination area before closing, then unintentional closing operations are suppressed, but the door closing operation may be delayed
Solution Approach 1:
The system employs periodic detection to monitor the communication terminal's position at regular intervals. By checking whether the terminal has moved out of the determination area across multiple detection cycles, the system balances the need for accurate closing initiation with minimizing unnecessary delays, ensuring the door closes promptly once the terminal is consistently outside the area.

AI summary
A vehicle control device includes: an acquisition section configured to acquire a determination result for a first area indicating whether or not a predetermined communication terminal is in a predetermined first area outside a cabin of a vehicle, and to acquire a determination result for a second area indicating whether or not the communication terminal is in a second area that is further away from the vehicle than the first area; and a control section configured to perform a closing operation of a vehicle door based on the acquired determination result for the first area and on the acquired determination result for the second area.
