Vehicle Pre-Air Conditioning Control for User Arrival Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pre-air conditioning systems in vehicles often stop operating before the user boards, leading to temperature deviations from the optimum setting, which can reduce user convenience and increase energy consumption.
Innovation Solution
An information processing device with a control unit that extends the operating time of the air conditioner in a vehicle if the user is detected to be present within a predetermined range at a predetermined timing after the initial pre-air conditioning start, ensuring the vehicle interior maintains an optimal temperature until the user boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the air conditioner operates for a fixed predetermined time, then energy consumption is controlled, but the vehicle temperature may deviate from the optimum setting when the user boards later
Solution Approach 1:
The air conditioner's operating time is changed from a fixed predetermined time to a dynamic time that is adjusted based on the detected user boarding time. The control unit extends or shortens the operation duration dynamically, allowing the system to adapt to actual user needs while maintaining temperature stability and optimizing energy consumption.
2Use of energy by moving object
If the air conditioner stops operating at the predetermined time, then energy consumption is reduced, but user convenience deteriorates due to temperature deviation
Solution Approach 1:
The system uses feedback from the user detection device (which detects when the user boards the vehicle) to adjust the air conditioner's operation. The control unit receives information about user boarding and dynamically modifies the operating time accordingly, ensuring the air conditioner runs long enough to maintain comfortable temperature while avoiding unnecessary energy consumption after the user has boarded.
3Ease of operation
If the air conditioner operates longer to maintain temperature, then user convenience is improved, but energy consumption increases
Solution Approach 1:
The operating time is dynamically adjusted based on actual user boarding time rather than using a fixed predetermined time. This dynamic adjustment allows the system to extend operation only as long as necessary to maintain temperature comfort, avoiding both premature shutdown and excessive runtime, thereby optimizing the balance between user convenience and energy consumption.

AI summary
An information processing device includes a control unit. The control unit extends an operating time of an air conditioner provided in a vehicle when the control unit determines that a user is present within a predetermined range from the vehicle at a predetermined timing when a predetermined operating time has elapsed from a start of pre-air conditioning inside the vehicle by the air conditioner.
