Vehicle Air Conditioning Remote Control Prediction Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning remote control systems for vehicles fail to notify users of the cooling or heating state in a timely manner due to communication delays and the need to determine the state within the vehicle, making it difficult to pre-condition the passenger compartment effectively.
Innovation Solution
An air conditioning remote control system that uses a portable terminal to transmit a start order to a server, which predicts the cooling or heating state based on vehicle location and temperature information, and displays the result on the terminal, allowing for immediate notification of the user without relying on in-vehicle determination, thus reducing communication delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cooling/heating state is determined inside the vehicle after the remote control order is transmitted, then the air conditioning device can be started, but the notification of the cooling/heating state to the user is delayed due to communication access time
Solution Approach 1:
The system performs cooling/heating prediction outside the vehicle before the air conditioning device actually operates. By predicting the cooling/heating state in advance based on remote control orders and environmental data, the system notifies users of the upcoming state without waiting for the actual in-vehicle determination, thereby eliminating notification delay while ensuring reliable device operation.
2Loss of time
If the cooling/heating state is determined immediately after the remote control order, then the user can receive timely notification, but the temperature in the vehicle passenger compartment cannot become clear unless air is circulated
Solution Approach 1:
The system introduces an external prediction server as an intermediary that performs cooling/heating prediction based on remote control orders, vehicle specifications, and environmental temperature data. This intermediary can determine the cooling/heating state immediately without waiting for actual air circulation and temperature stabilization in the vehicle, providing timely notifications while maintaining determination accuracy through sophisticated prediction algorithms.
3Measurement precision
If the cooling/heating state determination is performed inside the vehicle, then the actual state can be measured, but communication access causes delay in transmitting the result to the portable terminal
Solution Approach 1:
The system extracts the cooling/heating prediction function from the in-vehicle system and relocates it to an external server. By taking out the prediction capability from the vehicle interior, the system eliminates communication delays associated with transmitting determination results to portable terminals, as the prediction is performed externally and results are pushed to users without requiring repeated communication cycles.

AI summary
A portable terminal (300) transmits to a server (210) a request to start pre-air conditioning when the operations to begin pre-air conditioning are performed on the screen of the portable terminal (300). The server (210) predicts whether an air conditioning device (180) will begin cooling or heating on the basis of a set of vehicle location information stored in a vehicle information storage unit (214) and a set of temperature information acquired from a temperature information center, and transmits the prediction results to the portable terminal (300). As a consequence, it is possible to notify the cooling/heating state to a vehicle user in a timely manner.
