Vehicle Breath-Check Control to Cut Repeated Alcohol Tests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drunk driving prevention systems in vehicles are underutilized due to the need for frequent activation and the inconvenience of waiting for system messages, leading to user frustration and reduced adoption.
Innovation Solution
A drunk driving prevention system that selectively provides a guide display based on driver intent, using a sensor module to measure alcohol content and a control module to determine intoxication state, with features like facial mask detection and breath-checking logic adjustments, to minimize unnecessary pop-ups and enhance user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drunk driving prevention system is activated frequently to ensure safety, then the reliability of preventing drunk driving is improved, but the loss of time and user convenience deteriorates due to repeated alcohol tests and waiting for system messages
Solution Approach 1:
The system performs preliminary alcohol testing when the driver first enters the vehicle and activates electronic devices. The control module stores the alcohol test result and uses it for subsequent engine start attempts within a predetermined time period, eliminating the need for repeated full alcohol testing sequences and reducing user waiting time while maintaining prevention reliability
Solution Approach 2:
The control module creates a copy of the initial alcohol test result and reuses this copied information for multiple engine start attempts within the valid time period. This allows the system to maintain drunk driving prevention without requiring the driver to repeatedly perform the complete alcohol testing process, thus reducing time loss while preserving safety
2Ease of operation
If the system displays alcohol test guide information for every engine start input to ensure complete information provision, then the ease of operation is improved, but the device complexity increases due to unnecessary pop-ups and user frustration
Solution Approach 1:
The control module applies partial action by displaying alcohol test guide information selectively rather than for every engine start input. When the stored alcohol test result is valid and the current input is for engine start, the system suppresses the guide display, providing only the necessary information while reducing unnecessary pop-ups that cause user frustration and operational complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces the occurrence of unrequired pop-ups, saves time and effort, and ensures effective utilization by distinguishing between driver intent and vehicle operation states, thereby enhancing the overall convenience and effectiveness of the drunk driving prevention system.
Implementation Method 1
a sensor module measuring an alcohol content in exhaled breath of a driver during a breath-checking of the driver
Data Source
AI summary
Disclosed are a drunk driving prevention system and a method of controlling the system that includes a sensor module measuring a alcohol content in the exhaled breath of a driver during a breath-checking of the driver and a control module configured to check the intoxication state of the driver from the alcohol content measured by the sensor module to determine whether the breath-checking is complete and block an engine start when the breath-checking fails, wherein the control module includes a check unit displaying breath-checking guide information through a display unit and the check unit displays the breath-checking guide information based on an engine start input of the driver.
