Adaptive Vehicle Seat Massage Control via Audio and Bus Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current massage control systems in vehicle seats provide monotonous massage sequences and fail to adapt intensity to the driver's mental state or situational demands, potentially leading to distraction or discomfort.
Innovation Solution
A method to control massage units in vehicle seats based on audio entertainment signals and current vehicle operating information, adjusting massage intensity to match the driver's mental state and situational demands, such as during stressful or monotonous conditions, using a control device that processes vehicle data via a vehicle bus and adjusts vibration frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If massage intensity is increased to improve driver alertness, then driver attention is enhanced, but driver distraction increases in mentally demanding situations
Solution Approach 1:
The massage intensity is made dynamic and adaptive rather than fixed. The control device continuously monitors vehicle operating information and audio entertainment signals to automatically adjust massage intensity in real-time, allowing the system to respond to changing driver states and situational demands.
Solution Approach 2:
The system implements feedback control by monitoring vehicle operating information (such as driving behavior, vehicle state) and audio entertainment signals, then using this feedback to automatically adjust massage intensity. This closed-loop control ensures the massage remains appropriate to the current situation without requiring manual intervention.
Solution Approach 3:
The system changes the parameter of massage intensity based on multiple inputs including vehicle operating information and audio entertainment signals. By varying this parameter dynamically, the system optimizes driver alertness while avoiding excessive stimulation that could cause distraction.
2Ease of operation
If fixed massage programs are used to simplify control, then ease of operation is improved, but adaptability to different situations deteriorates
Solution Approach 1:
The massage system serves itself by automatically determining appropriate massage programs and intensity levels based on vehicle operating information and audio entertainment signals. The control device autonomously selects and adjusts massage parameters without requiring driver intervention, combining simplicity with high adaptability.
Solution Approach 2:
The control device performs multiple functions: it monitors vehicle operating information, processes audio entertainment signals, determines driver state, selects appropriate massage programs, and adjusts intensity levels. This multi-functional approach allows a single system to provide both simple operation and situation-specific adaptability.

AI summary
Method for controlling massage units (2-1 to 2-n) of a massage apparatus arranged in a seat (3) in a vehicle (10) for massaging an occupant, having the following method steps of: controlling (S2) massage units (2-1 to 2-n) integrated in the seat (3) on the basis of an audio entertainment signal (4); and changing (S4) an intensity of the massage provided by the massage units (2-1 to 2-n) on the basis of the entertainment signal (4) in a manner adapted to current operating information (8) relating to the vehicle (10). A seat arrangement for a vehicle or in a vehicle (10) for carrying out such a method is also involved.
