Steering Column and Seat Return Control for Driver Re-Entry
Solution Overview
Problem
Existing vehicle systems require drivers to manually switch the power source on and off and adjust the driver's seat position each time they exit and re-enter the vehicle, even when the power source is left on, causing inconvenience.
Innovation Solution
A vehicle control device that automatically adjusts the positional relationship between the steering column and driver's seat based on the detection of the driver's seat door state and the presence of the electronic key, allowing for seamless entry and exit without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the driver operates the operator to switch the driving power source on and off, then the driver's seat can be moved to the driving position, but the operation becomes inconvenient when the power source is left on
Solution Approach 1:
The system automatically detects driver return and autonomously positions the seat and steering column without requiring the driver to manually switch the power source or operate controls, making the system self-serve the driver's needs
Solution Approach 2:
The system prepares the driving position automatically upon detecting driver return, performing the seat and steering column adjustment in advance before the driver needs to drive, eliminating the need for manual intervention

AI summary
In a second power source control mode, after an entry/exit recognition unit recognizes that a user has exited a vehicle, when a driver's seat door sensor detects two or more times that the driver's seat door has been changed from an open state to a closed state and it is recognized that the user is in the vehicle, an entry/exit support control unit controls the positional relationship between a steering column and a driver's seat in a driver's seat area to be a returned positional relationship.
