Vehicle Air Conditioner Control via Preliminary Action and Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning control systems for vehicles do not perform automatic preliminary air-conditioning control effectively, especially when the vehicle is started remotely, and fail to adjust intensity based on environmental information and gear mode.
Innovation Solution
A system and method that includes a sensor group, gear mode sensing unit, timer, communication unit, control unit, start-up device, and air conditioner, which measures air-conditioning target deviation and selectively performs preliminary air-conditioning control by generating start-up and air-conditioning control signals, adjusting intensity based on environmental and time information, and performing control only in parking or neutral gear modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote start-up is performed, then vehicle start-up is enabled, but air-conditioning control is not automatically performed
Solution Approach 1:
The system performs preliminary air-conditioning control before the vehicle start-up by detecting remote start-up signals and automatically activating the air-conditioning system in advance, ensuring comfortable interior conditions are established before the driver enters the vehicle
2Device complexity
If air-conditioning control is performed based on simple on/off state, then control simplicity is maintained, but air-conditioning target deviation is not effectively addressed
Solution Approach 1:
The system continuously measures the deviation between current environmental conditions and air-conditioning targets using temperature and humidity sensors, then automatically adjusts air-conditioning operation based on this feedback to maintain optimal conditions
Solution Approach 2:
The system changes operational parameters of the air-conditioning system (such as compressor speed, fan speed, and refrigerant flow) based on measured environmental deviations from targets, enabling precise control while maintaining reasonable system complexity
3Productivity
If preliminary air-conditioning control is performed, then air-conditioning target is reached quickly, but energy consumption increases
Solution Approach 1:
The system performs partial air-conditioning operation during preliminary control phase, activating only essential functions (such as compressor and circulation fan) rather than full-system operation, thereby achieving acceptable interior conditions with reduced energy consumption compared to full-power operation

AI summary
A system for controlling an air conditioner for a vehicle includes a sensor group that generates environmental information, a gear mode sensing unit that senses a gear mode, a timer that counts time, a communication unit that receives a remote control signal and transmit air-conditioning control information, a control unit that generates a start-up control signal for a vehicle in response to the remote control signal or a set time, outputs or stops a start-up control signal in response to the gear mode, outputs an air-conditioning control signal when start-up is performed, performs transmission control through the communication unit by generating the air-conditioning control information, measures air-conditioning target deviation corresponding to the environmental information, and selectively performs preliminary air-conditioning control, a start-up device that performs start-up in response to the start-up control signal, and an air conditioner that performs air-conditioning control in response to the air-conditioning control signal.
