Driver Seat Self-Positioning for Accurate In-Vehicle Breath Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for determining a driver's inebriation within a vehicle require manual movement to a breathalyzer, distracting the driver and reducing test accuracy due to the need for manual positioning.
Innovation Solution
A system that automatically moves the driver's seat to a position optimized for breathalyzer testing, using a controller to output movement requests based on stored or detected body information, allowing the breathalyzer to initiate testing only when the seat is in the correct position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver manually moves to the breathalyzer position, then the breathing test can be performed, but the driver's concentration on driving is reduced and the operation becomes cumbersome
Solution Approach 1:
The driver's seat performs self-positioning by automatically moving to the optimal location for breathalyzer testing when a request signal is received, eliminating the need for manual driver intervention and maintaining driving concentration while ensuring accurate test positioning
Solution Approach 2:
The seat position is automatically adjusted to the optimal testing position before the breathalyzer test begins, ensuring the driver is properly positioned in advance without requiring manual movement during the testing process
2Reliability
If the driver manually positions themselves for the breath test, then the test can be conducted, but the driver needs to divert attention from driving
Solution Approach 1:
The seat automatically positions itself for optimal breathalyzer testing without requiring driver attention, maintaining both test reliability and continuous driving productivity by eliminating the need for manual positioning intervention
3Device complexity
If the breathalyzer requires manual positioning, then the system is simpler, but the testing process becomes more complex and distracting
Solution Approach 1:
The seat automatically moves to the optimal position when a movement request signal is received, maintaining simple system structure while significantly improving the ease of operation by eliminating manual positioning requirements for the driver

AI summary
Disclosed is a system and method for determining a driver's inebriation in a vehicle. The system includes a breathalyzer configured to be provided in an interior space of the vehicle to determine whether the driver is inebriated, through a driver's exhalation; and a controller configured to output a movement request signal for a driver's seat when determination of driver's inebriation by the breathalyzer is required and to control the breathalyzer to start the determination of driver's inebriation when the movement of the driver's seat is completed.
