Vehicle Seat Entry Position Control Using Driver Height Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic control methods for vehicle seat position adjustment cannot distinguish between intentional and unintentional adjustments, and they often require manual reconfiguration when the driver changes, leading to inconvenience.
Innovation Solution
A vehicle system equipped with a camera for obtaining image data, a seat motor for adjusting the seat position, and a controller that processes the image data to identify the driver's height and determine intended seat positions, allowing for automatic adjustment of the seat to match the driver's preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional electronic control methods are used to control seat position, then the seat position can be adjusted, but the system cannot distinguish between intentional and unintentional adjustments, causing inconvenience when driver changes
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture images of the driver, and uses image processing algorithms to extract height information. This intermediary system bridges the gap between the driver's physical presence and the seat control system, enabling automatic identification of driver characteristics without requiring manual input or direct communication of driver intention.
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with an automated optical measurement and control system. Instead of relying on manual lever operations or button presses, the system uses image processing to detect driver height and automatically controls the seat motor to adjust the seat position, substituting mechanical driver actions with an automated electromechanical system.
2Measurement precision
If manual seat position adjustment is required when driver changes, then the driver can set preferred position, but this process is time-consuming and inconvenient
Solution Approach 1:
The patent performs preliminary action by automatically capturing driver height information through image processing as soon as the driver enters the vehicle, before the driver would need to manually adjust the seat. The system pre-determines the appropriate seat position based on extracted height data and automatically adjusts the seat, eliminating the need for time-consuming manual manipulation while ensuring accurate positioning tailored to the driver's body characteristics.
3Stability of the object's composition
If seat automatic control is performed based on final seat position, then the system can maintain consistency, but it cannot adapt to different drivers with different body types
Solution Approach 1:
The patent applies local quality by tailoring the seat position to the specific local characteristic of each driver's body type, particularly height. Instead of using a universal or fixed seat position for all drivers, the system extracts individual height information through image processing and adjusts the seat position accordingly, ensuring that each driver receives a customized seating position optimized for their specific body dimensions while maintaining system stability through consistent automated control.
