Vehicle Server Predicting Occupant Destination for Home Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling external devices in a home network based on vehicle location information often result in unnecessary power consumption, as they do not accurately predict which spaces will be used upon arrival, leading to inefficient operation of devices in unused areas.
Innovation Solution
An electronic device and method that utilize a server to receive movement and occupant information from a vehicle, select appropriate external devices based on this data, and display a confirmation message to the user, allowing them to consent to controlling these devices upon arrival, thereby minimizing unnecessary operations and optimizing energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all external devices are operated in advance based on vehicle location information, then user convenience is improved, but power consumption increases unnecessarily
Solution Approach 1:
The system performs preliminary actions by predicting the user's destination space based on vehicle location and occupant information before arrival, and pre-controllers only the external devices in that predicted space. This selective preliminary action avoids operating all devices unnecessarily, thus reducing power consumption while still providing user convenience.
Solution Approach 2:
Instead of uniformly operating all external devices across the entire home network, the system applies local quality by identifying and controlling only the specific external devices in the predicted destination space. This localized approach ensures energy is consumed only where needed, resolving the contradiction between convenience and energy waste.
2Ease of operation
If external devices are pre-operated upon arrival, then user convenience is improved, but device complexity increases
Solution Approach 1:
The system enables self-service by automatically predicting the user's destination space and pre-controlling relevant external devices without requiring user intervention. The server autonomously processes vehicle location data, occupant information, and device control decisions, simplifying the user experience while managing system complexity through automated algorithms.
Solution Approach 2:
The server acts as an intermediary between the vehicle device and external devices, mediating the complex processes of data reception, space prediction, device selection, and control signal transmission. This intermediary role centralizes complexity management, allowing the system to provide convenient automated control without distributing complexity across multiple components.
3Device complexity
If external devices are controlled without accurate space prediction, then system simplicity is maintained, but energy efficiency deteriorates
Solution Approach 1:
The system performs preliminary space prediction based on vehicle location and occupant information before controlling external devices. This preliminary action enables accurate identification of the destination space, ensuring that only devices in the correct space are activated, thereby improving energy efficiency without significantly increasing system complexity.

AI summary
An example server may include at least one communication module (e.g., including communication circuitry), and a processor. The processor may be configured to receive movement information and first occupant information related to a vehicle device, using the at least one communication module, select at least one first external device from among a plurality of external devices related to a local network, based on the movement information and the first occupant information, calculate a first display time to display a first confirmation message asking whether to control the at least one first external device, based on an arrival time included in the movement information and at least one first operation time of the at least one first external device, and transmit a first request signal causing display of the first confirmation message on a display of the vehicle device at the first display time, using the at least one communication module.
