Vehicle Seat Control Logic for Collision-Safe One-Touch Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The one-touch seat control function in vehicles can lead to unintended and unwanted seat operations during accidents due to insufficient clearance between the seat cushion and the door, causing the button to be pressed unintentionally, resulting in safety hazards.
Innovation Solution
A seat control apparatus that includes a collision detection module, a seat operation mode determination module, and seat control modules to differentiate between automatic and manual modes, deactivating the automatic mode during a collision and allowing manual mode operation regardless of the collision occurrence signal, thereby preventing unintended seat movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one-touch seat control function is implemented, then ease of operation is improved, but reliability deteriorates due to unintended operations during accidents
Solution Approach 1:
The control apparatus applies preliminary anti-action by detecting collision occurrence in advance and proactively deactivating the one-touch seat control function before unintended operations can occur. The collision detection module monitors for accidents, and when detected, the control apparatus prevents the seat control from responding to button inputs, thereby counteracting potential harmful effects before they manifest.
Solution Approach 2:
The control apparatus introduces an intermediary collision detection mechanism between the button input and seat control execution. This intermediary layer checks for collision conditions and blocks the control signal transmission when accidents are detected, preventing direct coupling between user input and seat movement that would otherwise cause unintended operations.

AI summary
A seat control apparatus is provided. The seat control apparatus may include: one or more processors, and memory storing instructions that, when executed by the one or more processors, cause the seat control apparatus to detect a collision of a vehicle, output, based on the detection, a collision occurrence signal; determine a seat operation mode of the vehicle between an automatic mode and a manual mode, output, based on the determination, one of an automatic mode seat operation request command or a manual mode seat operation request command, determine, based on the collision occurrence signal, whether to transmit one of the automatic mode seat operation request command or the manual mode seat operation request command; and drive, based on the one of the automatic mode seat operation request command or the manual mode seat operation request command, one or more seat motors to control a seat of the vehicle.
