Vehicle Seat Posture Control Using Body Shape Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat control systems struggle to automatically achieve an appropriate driving posture for occupants based on their individual body shapes, often requiring manual adjustments and failing to replicate the correct seat position without stored occupant-specific information.
Innovation Solution
A seat control system that inputs body shape information, extracts corresponding posture range information from a body shape posture range correspondence table, and controls the seat drive unit to adjust the vehicle seat posture within the specified range, ensuring an appropriate driving posture is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment procedure is provided to occupants, then driving posture can be adjusted appropriately, but occupants may not execute the procedure correctly or know the specified procedure
Solution Approach 1:
The system automatically detects occupant body shape and adjusts seat posture without requiring manual operation by the occupant. The seat control system performs self-service by using sensors to measure body shape information and automatically controlling the seat drive means to achieve appropriate driving posture, eliminating the need for occupants to know or execute adjustment procedures
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated control system that uses body shape detection and control algorithms. Instead of relying on occupants to manually adjust seat components, the system uses sensors to detect body shape and automatically controls the seat drive means through electronic control, substituting mechanical manual operation with an automated electromechanical system
2Extent of automation
If seat information is stored in storage means, then seat position can be replicated automatically, but the stored position may not be appropriate for all occupants or body shapes
Solution Approach 1:
The system transitions from static stored seat information to dynamic body shape-based adjustment. Instead of relying on pre-stored seat positions that are fixed and cannot adapt to different occupants, the system dynamically detects body shape information and automatically adjusts seat posture in real-time, making the system adaptable to various body shapes and sizes
Solution Approach 2:
The patent changes the control parameter from fixed stored seat positions to variable body shape parameters. The system measures actual body shape information and uses these parameters to determine appropriate seat posture, allowing the seat position to be dynamically adjusted based on occupant characteristics rather than relying on predetermined stored values
3Extent of automation
If automatic seat adjustment based on body shape is implemented, then appropriate driving posture can be achieved automatically, but the system complexity increases
Solution Approach 1:
The system uses a multi-functional approach where the seat control system integrates body shape detection, posture range determination, and seat adjustment functions. By making the control system universal and multi-functional, the patent reduces the need for separate dedicated components for each function, thereby managing system complexity while achieving automatic driving posture adjustment

AI summary
A seat control system for setting a driving posture and a seat control method is provided, in which body shape information indicating a body shape is input. Posture range information corresponding to the input body shape information is extracted from body shape posture range correspondence information, in which the body shape information and posture range information indicating a posture range of a vehicle seat corresponding to a driving posture range correspond to each other. A posture of the vehicle seat is controlled such that the posture of the vehicle seat falls within the posture range of the vehicle seat indicated by the extracted posture range information.
