Vehicle Seat Massage Control Based on Input and Seat State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat massage systems lack control mechanisms to determine when to activate the massage function based on user input, vehicle state, and operational settings, leading to potential durability issues and reduced lifespan due to indiscriminate operation.
Innovation Solution
A seat control apparatus that identifies user input devices and determines whether to perform a massage function based on the type of input device, vehicle state, seat location, and compulsory driving settings, using separate driving parts for seat adjustment and massage functions, and controlling the massage function accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the massage function is operated indiscriminately without considering driving situation or seat operation state, then user convenience is improved, but durability of the seat is degraded and mechanical lifespan becomes shorter
Solution Approach 1:
The system dynamically adjusts massage function availability based on real-time detection of driving state (manual/automatic mode) and seat operation state (adjustment in progress or completed). The controller enables or disables the massage function according to the current operational context, preventing indiscriminate operation while maintaining user convenience when conditions are appropriate.
Solution Approach 2:
The system continuously monitors the state of the driving mode switch and seat adjustment operations, using this feedback to determine whether to permit massage function activation. This feedback mechanism ensures that the massage function is only available when it will not compromise seat durability or mechanical lifespan.
2Ease of operation
If the massage function is activated during seat location control, then user convenience is improved, but unnecessary operation occurs when automatic switch is used
Solution Approach 1:
The system dynamically determines massage function activation based on the type of switch input detected. When an automatic switch is detected during seat location control, the system prevents massage function activation. When a manual switch is detected, the system permits massage function activation, thereby avoiding unnecessary operation while maintaining user convenience.
3Device complexity
If the massage function operates without considering input device type, then system simplicity is maintained, but control precision is reduced
Solution Approach 1:
The system dynamically adjusts its control logic based on the detected input device type. When a manual switch is detected, the system permits massage function operation. When an automatic switch is detected, the system prevents massage function operation during seat location control. This dynamic adjustment enhances control precision without significantly increasing system complexity.

AI summary
A seat control apparatus receives a user input from a user through an input part. The seat control apparatus may identify, among a plurality of input devices included in the input part, a type of an input device corresponding to the user input, and determine whether the massage function is to be performed, based on information of at least one of the identified type of the input device, a state of a host vehicle, a location state of the seat, a compulsory driving setting state of the massage function, or any combination thereof.
