Remote Engine Start Control for Indoor Exhaust Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote engine starting in vehicles can lead to environmental deterioration when parked indoors, as existing systems do not adequately account for indoor conditions, potentially harming the cabin environment due to exhaust.
Innovation Solution
A vehicle equipped with an ambient environment detection system, including sensors like outside air temperature and carbon monoxide sensors, that determines if the environment is suitable for engine operation and automatically stops the engine if conditions are not met, ensuring a safer and healthier cabin environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the engine is started by remote operation when the vehicle is parked indoors, then the engine can be warmed up or air conditioning can be executed, but the environmental state indoors or in the occupant cabin deteriorates due to exhaust
Solution Approach 1:
The system performs preliminary detection of the parking environment (indoor vs. outdoor) before allowing engine start. The detection sensor identifies whether the vehicle is parked in an enclosed space, and based on this preliminary information, the controller either permits or prohibits remote engine starting to prevent exhaust accumulation before it becomes harmful
Solution Approach 2:
The system continuously monitors the parking environment using detection sensors and provides feedback to the control unit. When the sensor detects indoor parking conditions, the controller receives feedback and automatically prohibits remote engine starting, creating a closed-loop control system that adapts to environmental conditions
2Ease of operation
If the engine is started by remote operation without environmental detection, then the operation is simple and quick, but the cabin environment may be compromised by exhaust accumulation
Solution Approach 1:
The system automatically detects the parking environment and makes the decision to permit or prohibit engine starting without requiring user input. The detection sensor and controller work together to self-determine whether remote starting is safe, eliminating the need for complex user judgments while protecting cabin air quality
Solution Approach 2:
The detection sensor acts as an intermediary between the remote start command and the engine control system. It provides environmental information to the controller, which then mediates whether the engine should actually start, creating a safety layer between the user's intent and the physical action
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
This solution effectively suppresses environmental deterioration by automatically stopping the engine when indoor conditions are not appropriate, providing a safer and healthier cabin environment during remote engine starting.
Implementation Method 1
the ambient environment detection sensor may be an outside air temperature sensor or a carbon monoxide concentration sensor mounted on the vehicle

AI summary
In a case where a determination is made, after an engine is started based on a remote operation, that an ambient environment of a vehicle is not a predetermined appropriate environment based on a detection value from an ambient environment detection sensor configured to detect the ambient environment of the vehicle, the engine is stopped. As a result, it is possible to suppress a deterioration of an environmental state around the vehicle or an occupant cabin. As a result, it is possible to take more appropriate measures when the engine is started based on the remote operation.
