Vehicle Seat Swivel Control with Obstruction Pre-Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle seat swivel functions are often restricted due to obstruction by other components, leading to user discomfort and potential reduction in seat functions to accommodate space, which can result in customer dissatisfaction.
Innovation Solution
A vehicle seat control system that includes a seat control module and a seat controller to collect and analyze seat state data, predict obstruction conditions, and perform pre-processing controls to remove obstructions, allowing smooth seat swivel operations by adjusting the leg rest, backrest, and sliding functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat size and center console size are reduced to secure organic space for seat swivel, then the seat swivel function can be operated, but existing seat functions are reduced and passenger convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically adjusting the leg rest and backrest to predetermined positions before executing the seat swivel function. This pre-positioning removes potential obstructions and creates the necessary space for swivel operation without requiring permanent reduction of seat components or functions.
Solution Approach 2:
The seat components (leg rest, backrest) are made dynamically adjustable rather than fixed. The control unit automatically changes the positions of these components based on the operational context, allowing the seat to adapt its configuration for swivel operation while maintaining full functionality in other contexts.
2Adaptability or versatility
If the seat components are fixed in size to maintain existing seat functions, then passenger convenience is maintained, but obstruction occurs during seat swivel operation
Solution Approach 1:
Before the seat swivel operation is initiated, the control unit automatically performs preliminary adjustments by positioning the leg rest and backrest in predetermined positions. This pre-action removes obstructions that would otherwise prevent smooth swivel operation, allowing both fixed seat dimensions and unobstructed swivel movement.
3Reliability
If the seat swivel function is restricted to avoid obstruction, then component damage is prevented, but user comfort deteriorates
Solution Approach 1:
The control unit performs preliminary positioning of the leg rest and backrest before enabling seat swivel operation. This pre-adjustment ensures that components are in safe positions that prevent obstruction and potential damage during swivel, while still allowing the full range of comfortable swivel motion for the user.

AI summary
A vehicle seat control system includes: at least one seat comprising an one or more electronic devices for a seat sliding function, a backrest angle adjustment function, a leg-rest angle adjustment function, and a seat swivel function; a seat control module disposed in each seat to collect seat state data of the corresponding seat and control the functions of the one or more electronic devices based on an applied command; and a seat controller disposed to correspond to the seat control module, predicting an obstruction condition by another component during seat swivel by checking the seat state data if receiving a seat swivel request from a user, removing the obstruction condition through a pre-processing control by using the seat control module, and then performing a seat swivel control.
