Vehicle Control Handover via Breathalyzer and Driver Identity Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to effectively prevent drunk driving by not transferring vehicle control rights to passengers when the registered driver is inebriated, leading to inefficiencies and safety risks.
Innovation Solution
A system that includes an input unit for transferring vehicle control rights, a sobriety determination unit using a breathalyzer to assess the driver's inebriation, a driver verification unit for identifying personal information, and a control unit that transfers control to a passenger if they are deemed sober, ensuring the passenger can safely operate the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a breathalyzer tester is provided in the vehicle to measure driver inebriation, then the ability to detect drunk driving is improved, but the control right cannot be transferred to a sober passenger when the driver is inebriated
Solution Approach 1:
The system separates the detection function (sobriety determination unit) from the control function (control right management unit). The breathalyzer component independently measures inebriation levels, while the control unit independently manages control right transfers based on measurement results, allowing both functions to operate autonomously and effectively
Solution Approach 2:
The control unit acts as an intermediary between the sobriety determination unit and the vehicle control system. It receives inebriation measurement results, determines whether control right transfer is necessary, and executes the transfer to a designated passenger, thereby connecting detection and control functions
2Reliability
If police checks of drivers for inebriation are conducted, then drunk driving can be detected, but various inconveniences and inefficiencies occur
Solution Approach 1:
The system performs preliminary sobriety testing before the driver operates the vehicle. The control unit is configured to prevent vehicle operation unless the driver passes the breathalyzer test or has transferred control rights, eliminating the need for subsequent police checks and ensuring prevention occurs in advance
Solution Approach 2:
The vehicle system autonomously performs sobriety testing and control right management without requiring external police intervention. The driver self-tests via the integrated breathalyzer, and the control unit automatically enforces driving restrictions or facilitates control transfer based on results, making the system self-sufficient
3Ease of operation
If the driver is allowed to operate the vehicle after breathalyzer measurement, then ease of operation is maintained, but the driver can ignore the measurement result and continue drunk driving
Solution Approach 1:
The control unit is configured to automatically prevent vehicle operation when inebriation is detected, countering the driver's potential intent to drive drunk before the action occurs. The system proactively blocks the ignition or operation based on breathalyzer results, eliminating the opportunity for the driver to ignore the measurement and drive
Solution Approach 2:
The control unit continuously monitors breathalyzer measurement results and provides real-time feedback by enabling or disabling vehicle operation accordingly. When inebriation is detected, the system immediately provides feedback by preventing operation, and when sobriety is confirmed or control is transferred, it enables operation, creating a closed-loop control system

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents drunk driving by ensuring the vehicle is operated by a sober passenger, reducing the risk of accidents and legal consequences, while also preventing the inebriated driver from attempting to drive.
Implementation Method 1
a sobriety determination unit configured to determine a current driver's inebriation state through a breathalyzer provided in the vehicle

AI summary
Disclosed is a system for preventing drunk driving of a vehicle, the system including: an input unit through which a transfer intention to transfer a control privilege of a vehicle from a registered driver to a passenger is input; a sobriety determination unit configured to determine a current driver's inebriation state through a breathalyzer provided in the vehicle when the transfer intention is input through the input unit; a driver verification unit configured to identify personal information of the current driver seated on a driver's seat; and a control unit configured to transfer the control privilege of the vehicle to the passenger when the passenger is measured as being able to drive by the sobriety determination unit and the passenger and the current driver are identified to be the same by the driver verification unit.
