Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle air circulation systems require frequent manual mode switching based on distance from contaminating vehicles, leading to indoor air quality issues due to inadequate consideration of external air conditions, resulting in uncomfortable and unhealthy environments for occupants.
Innovation Solution
An apparatus and method that utilize outdoor and indoor sensors to measure fine dust concentrations, determine external air quality, and adjust air circulation modes and indoor air cleaner operation strengths to maintain comfortable and clean indoor air by avoiding contaminating sources and optimizing route selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air circulation mode is switched based on distance from front vehicle only, then the system complexity is reduced, but the indoor air quality management becomes inadequate when outdoor air conditions are poor
Solution Approach 1:
The system changes the control parameter from simple distance-based switching to a comprehensive air quality index that integrates multiple parameters including fine dust concentration, nitrogen dioxide levels, and carbon monoxide concentrations. This allows the system to make informed decisions about air circulation modes based on actual air quality conditions rather than just distance metrics.
Solution Approach 2:
The patent introduces an air quality assessment module that acts as an intermediary between environmental sensors and the air circulation control system. This intermediary processes sensor data, compares it with threshold values, and generates appropriate control commands, thereby decoupling the complexity from the basic switching logic while improving air quality management.
2Object-affected harmful factors
If the driver manually switches air circulation mode frequently, then the air quality can be adjusted to some extent, but the ease of operation deteriorates and driver burden increases
Solution Approach 1:
The system implements self-service by automatically monitoring air quality parameters and switching between indoor and outdoor air circulation modes without driver intervention. The control system continuously reads sensor data, assesses air quality conditions, and autonomously adjusts the air circulation mode to maintain optimal indoor air quality.
Solution Approach 2:
The patent establishes a feedback loop where sensor data about indoor and outdoor air quality continuously feeds back to the control system. Based on this feedback, the system dynamically adjusts the air circulation mode, creating a closed-loop control mechanism that automatically responds to changing air quality conditions.
3Productivity
If the vehicle travels directly to destination, then the productivity is maintained, but the vehicle may be exposed to contaminated air areas
Solution Approach 1:
The system performs preliminary action by predicting future air quality conditions along the planned route and proactively adjusting the air circulation mode before the vehicle enters contaminated areas. The control system uses real-time sensor data and route information to anticipate poor air quality zones and prepare appropriate responses.
Solution Approach 2:
The patent implements dynamic route adjustment capabilities where the navigation system can modify the travel route in real-time based on detected air quality conditions. When contaminated areas are identified, the system dynamically recalculates and suggests alternative routes that avoid poor air quality zones while minimizing deviation from the original destination.
Data Source
AI summary
An apparatus and a method for controlling a vehicle, which control a route of the vehicle or an air circulation mode of the vehicle based on an outdoor air condition of an autonomous driving vehicle and control an indoor air cleaner of the vehicle based on an indoor air condition. In some implementations, an apparatus for controlling a vehicle includes an outdoor measurement sensor attached to an exterior of the vehicle and measuring an external fine dust concentration, a communicator receiving, from an environment server, a local fine dust concentration corresponding to a position of the vehicle, and when a difference between the measured external fine dust concentration and the received local fine dust concentration exceeds a set allowance, a controller checking whether an object generating fine dust exists outside the vehicle and allowing the vehicle to travel while avoiding the object when it is confirmed that the object exists.
