Vehicle Smell Detection and Position Sharing to Avoid Smoke Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems cannot detect smoking in vehicles or control vehicle travel to avoid the negative effects of smoking on other vehicles or areas.
Innovation Solution
A vehicle control system that includes smell detection units in vehicles to determine if smoking is occurring, with position information sharing between vehicles to alert drivers of nearby smoking vehicles, allowing them to take detour routes and avoid each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If vehicle-to-vehicle communication is implemented to share position information, then drivers can avoid smoking vehicles through warnings, but the device complexity increases due to adding smell detection units and communication systems
Solution Approach 1:
The system divides the problem into two independent parts: the smoking vehicle (first vehicle) with smell detection and notification capabilities, and the non-smoking vehicle (second vehicle) with position comparison and warning output capabilities. This segmentation allows each vehicle to have a simplified, dedicated function rather than requiring all vehicles to have complete detection and control systems.
Solution Approach 2:
The patent introduces communication units as intermediaries that transmit position information between vehicles. Instead of direct detection and response, the system uses communicated position data as an intermediary to enable avoidance behavior, reducing the complexity of direct sensor-to-action coupling.
2Object-affected harmful factors
If real-time smell detection and position sharing is implemented, then drivers can be alerted to avoid smoking vehicles, but the loss of time occurs due to notification processing and route adjustment
Solution Approach 1:
The system continuously monitors and shares position information in advance before the vehicles come into harmful proximity. By maintaining real-time position data exchange and performing preliminary smell detection, the system enables drivers to take preventive avoidance actions before the harmful situation arises, rather than reacting after exposure begins.
Solution Approach 2:
The system establishes a continuous feedback loop where position information is constantly shared between vehicles, the approach determination unit continuously evaluates proximity, and warning outputs are provided in real-time. This ongoing feedback enables dynamic route adjustment and continuous avoidance behavior, minimizing both exposure time and decision-making delays.

Function Achieved in This Case
Effectively prevents the negative impacts of smoking on other vehicles by enabling drivers to avoid smoking vehicles through position-based warnings and route adjustments.
Implementation Method 1
a smell detection unit configured to detect a smell in the first vehicle
Data Source
AI summary
A vehicle control system includes: a first vehicle including a smell detection unit, a smell determination unit configured to determine whether an intensity of the smell is equal to or larger than a predetermined threshold value, a first acquisition unit configured to acquire first vehicle position information indicating a position of the first vehicle, and a notification unit configured to notify a second vehicle about the first vehicle position information when the smell determination unit determines that the intensity of the smell is equal to or larger than the predetermined threshold value; and a second vehicle configured to communicate with the first vehicle and including an information output processing unit configured to cause an information output unit to output a warning notifying about a presence of the first vehicle when an approach determination unit determines that first vehicle is positioned less than the predetermined distance from the second vehicle.
