Vehicle Enclosed-Space Detection for Harmful Gas Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles do not effectively alert occupants or individuals in enclosed environments to the presence of harmful gases emitted from power sources, which can lead to adverse health effects due to increased gas exposure.
Innovation Solution
A control apparatus with processors and memory that determines the vehicle's enclosed environment and presence of occupants or individuals, triggering notifications to stop the power source or request emergency assistance when harmful gases are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle operates in an enclosed environment with power sources (engine, battery, fuel cell), then the vehicle can function normally, but harmful gases accumulate and adversely affect human bodies
Solution Approach 1:
The control apparatus determines whether the vehicle is in an enclosed environment before harmful gas accumulation becomes severe. By proactively identifying the enclosed environment condition and notifying occupants in advance, the system prevents harmful exposure rather than responding after damage occurs
Solution Approach 2:
The control apparatus acts as an intermediary between the power source system and the occupants. It monitors the operational state of power sources (engine, battery, fuel cell) and mediates by issuing notifications when conditions indicate potential harmful gas accumulation, protecting occupants without stopping normal vehicle operation
2Object-affected harmful factors
If the vehicle discharges exhaust gas to outside the vehicle to reduce harmful gas concentration, then harmful gas exposure is reduced, but the vehicle cannot operate effectively in enclosed environments
Solution Approach 1:
The control apparatus continuously monitors the operational state of power sources and the vehicle environment. When it detects that the vehicle is operating in an enclosed environment with power sources active, it provides feedback by notifying occupants, enabling them to take appropriate actions (ventilation, evacuation) without preventing the vehicle from operating
Solution Approach 2:
Rather than waiting for harmful gas accumulation to reach dangerous levels or forcing exhaust discharge, the system takes preliminary action by notifying occupants in advance. This allows occupants to proactively open windows or evacuate before harmful effects occur, maintaining vehicle operability while protecting occupants

AI summary
A control apparatus to be mounted on a vehicle includes one or more processors, and one or more memories each storing a program to be executed by the one or more processors. The program includes one or more commands. The one or more commands are each configured to cause the one or more processors to: determine whether the vehicle is in an enclosed environment; and execute abnormality notification control to output an abnormality notification based on a result of a power-source-state determination and a result of a presence determination when the one or more processors determine that the vehicle is in the enclosed environment. The power-source-state determination is a determination regarding a state of a power source of the vehicle, and the presence determination is a determination as to whether there is a person inside or outside the vehicle.
