Vehicle Cabin Ventilation Control Using Automatic Multi-Window Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ventilating a vehicle cabin efficiently is time-consuming and requires significant effort, especially when multiple windows need to be opened, and it is dangerous for drivers to perform this operation while driving.
Innovation Solution
An information processing apparatus with a controller that receives a single user action to start ventilation, automatically opening multiple windows and controlling the air conditioner to maximize outside air intake and circulation, allowing for safe and efficient cabin ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple windows are opened manually to ventilate the vehicle cabin, then ventilation effectiveness is improved, but user time and effort are increased
Solution Approach 1:
The patent combines multiple window operations into a single unified control action. When the user activates ventilation mode, the controller simultaneously opens multiple windows (front and rear windows on both left and right sides) rather than requiring individual manual operation of each window, thereby reducing user time and effort while maintaining effective ventilation
Solution Approach 2:
The ventilation system performs self-service by automatically controlling window openings and air conditioner operations once activated. The controller autonomously manages the ventilation process including opening windows, adjusting air intake, and circulating air without requiring continuous user intervention, thereby eliminating the need for manual window-by-window operation
2Reliability
If multiple windows are opened manually to ventilate the vehicle cabin, then ventilation effectiveness is improved, but operation safety is worsened when driver is driving
Solution Approach 1:
The system enables self-service ventilation by automatically executing the entire ventilation sequence through a single user activation. The controller autonomously opens multiple windows, adjusts air conditioner settings, and manages air circulation without requiring the driver to manually operate multiple windows, ensuring driving safety is maintained while achieving effective ventilation
Solution Approach 2:
The patent segments the ventilation control function from manual window operations. The controller acts as an intermediary that receives a single user command and automatically executes the complex sequence of opening multiple windows and adjusting air conditioning, thereby separating the safety-critical driving task from the ventilation task
3Reliability
If air conditioner is used for ventilation, then air circulation is improved, but power consumption is increased
Solution Approach 1:
The patent applies partial action by using the air conditioner at reduced capacity for ventilation compared to cooling mode. The air conditioner operates to provide sufficient air circulation for ventilation purposes without maximizing its output, thereby achieving adequate air circulation while minimizing power consumption during ventilation operations

AI summary
An information processing apparatus receives a first action instructing to start ventilation of an interior space in a vehicle cabin by a user and causes a vehicle to perform a first operation including at least opening a plurality of windows that can be opened and closed and that provided in the vehicle when the first action is received. Further, when a predetermined condition indicating the end of ventilation of the interior space in the vehicle cabin is satisfied, the information processing apparatus causes the vehicle to end the first operation and causes the vehicle to return to the state before performing the first operation.
