Vehicle Door Control Device with Detection Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door opening and shutting systems can fail to operate as intended when the occupant's hand is positioned at the boundary of the measuring area, leading to unstable operations and incorrect door control.
Innovation Solution
A control device and vehicle control system that include an operation detecting unit to sense the occupant's intention through a portion of their body, a notification unit to inform the occupant of the operation detection area, and a control section to confirm the operation by a predetermined time before automatically opening or closing the vehicle door, preventing erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the measuring area boundary is used for operation detection, then the coverage area is maximized, but the operation stability deteriorates
Solution Approach 1:
The notification unit provides visual feedback to the occupant about the detection area boundaries and current detection state. This feedback mechanism helps the occupant understand where their body should be positioned for reliable detection, reducing unstable operations at boundaries while maintaining full coverage
Solution Approach 2:
The notification unit activates before door operation to preliminarily inform the occupant about the detection area and required body position. This preliminary guidance prevents unstable operations by preparing the occupant to position their body correctly within the optimal detection zone
2Speed
If automatic door operation is implemented without confirmation, then the operation speed is improved, but the error rate increases
Solution Approach 1:
The notification unit performs preliminary action by informing the occupant of the detected operation intention before the door actually moves. This confirmation step allows rapid automatic operation while preventing erroneous activation, as the system verifies the occupant's intention through the notification response
Solution Approach 2:
The notification unit provides immediate feedback when an operation is detected, allowing the system to confirm the occupant's intention before executing door movement. This feedback loop maintains high operation speed by using pre-prepared notification sequences while ensuring accuracy through intention verification

AI summary
A control device includes: an input section to which a first signal indicating the presence or absence of an operation for operating an opening and closing body of a vehicle which is performed using a portion of the body of an occupant is input from an operation detecting unit; and a control section which performs notification to the occupant using a notification unit when there is a state where the operation has been detected by the operation detecting unit, based on the first signal, and performs control for operating the opening and closing body, based on the operation.
