Steering Wheel Position Control via Head Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering wheel position adjustment systems require complex operations and are not synchronized with seat position changes, leading to unsuitable steering wheel positions for drivers.
Innovation Solution
A steering wheel position control system that includes a head position acquisition part, seat movement detection part, steering wheel position calculation part, and adjustment part, using a camera, sensors, and an ECU to automatically adjust the steering wheel based on driver head position and seat movement, ensuring optimal positioning without driver intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the steering wheel position is adjusted separately from seat position change operation, then the steering wheel can be repositioned to suit the driver, but the operation becomes complicated
Solution Approach 1:
The patent combines the steering wheel position adjustment function with the seat position adjustment operation. When the seat position is changed, the system automatically integrates steering wheel position recalculation and adjustment into the same operational sequence, eliminating the need for separate adjustment steps and simplifying the overall operation for the driver.
Solution Approach 2:
The system enables automatic steering wheel position adjustment based on detected seat position changes. The control unit automatically recalculates the optimal steering wheel position and actuates the adjustment mechanism without requiring additional driver input, allowing the system to serve itself rather than requiring manual intervention for each adjustment.
2Adaptability or versatility
If the steering wheel position is not adjusted when seat position changes, then the system remains simple, but the steering wheel position becomes unsuited to the driver
Solution Approach 1:
The system implements feedback by continuously monitoring seat position through detection units and using this information to automatically recalculate and adjust the steering wheel position. The control unit receives feedback from seat position changes and responds by adjusting the steering wheel to maintain optimal positioning, creating a closed-loop adaptive system.
Solution Approach 2:
The steering wheel position is made dynamic rather than fixed, automatically adapting to changes in seat position. The system continuously updates the steering wheel position based on real-time seat position data, allowing the steering wheel to dynamically adjust its position to remain suited to the driver's new configuration.

AI summary
A steering wheel position control system includes a head position acquisition part for acquiring a position of a head part of a driver, a seat movement detection part for detecting movement of a seat, on which the driver is seated, a steering wheel position calculation part for calculating a position of a steering wheel based on the position of the head part acquired by the head position acquisition part when the movement of the electric power seat is detected by the seat movement detection part, and a steering wheel position change part for moving the steering wheel to the position of the steering wheel calculated by the steering wheel position calculation part.
