Vehicle IoT State Display for Low-Latency Car-to-Home Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Car-to-Home service experiences long waiting times for users due to the time-consuming information transmission through multiple servers, causing discomfort for drivers waiting for command results.
Innovation Solution
A method and system that utilize a first server operated by the vehicle manufacturer to inquire and store the current state of IoT devices, allowing for faster information retrieval and display, and enabling immediate correction of displayed information if it differs from the updated server data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication between the head unit and the remote IoT device is performed through a plurality of servers, then the IoT device can be controlled remotely from the vehicle, but the transmission of information takes a long time which increases the waiting time of the user
Solution Approach 1:
The system performs preliminary actions by having the first server proactively push current state information of the IoT device to the head unit before the user actually requests it. This way, when the user views the state through the display, the information is already available, eliminating the waiting time that would otherwise occur during the multi-server communication process.
2Measurement precision
If the current state of the IoT device is inquired through multiple servers, then accurate real-time state information can be obtained, but the time required for information transmission increases
Solution Approach 1:
The system extracts the state information retrieval function from the multi-server communication path and implements it through a direct push mechanism from the first server to the head unit. This separation allows the accurate state information to be obtained through the established server connection while the display is updated immediately through the direct push, bypassing the time-consuming multi-server inquiry process for each state check.
3Reliability
If the system waits for confirmation of command execution before displaying results, then accurate execution status can be shown, but the user experiences longer waiting time
Solution Approach 1:
The system implements feedback by having the first server continuously monitor and push updated state information to the head unit after command transmission. This allows the display to show execution results as soon as they are available from the server, rather than waiting for the complete multi-server confirmation cycle, thus maintaining reliability while reducing user waiting time.

AI summary
A method and system for controlling a vehicle shorten waiting time for a user to receive a result of a command when implementing a Car-to-Home service that communicates through servers. The method includes: inquiring, through a first server, a current state of an Internet of Things (IoT) device linked to enable remote control from a vehicle and storing the inquired IoT device current state; upon generation of the request from the vehicle, fetching information about the current state of the IoT stored in the first server and displaying the information through a display; re-inquiring the current state to update the information about the current state of the IoT stored in the first server; and if the information about the current state of the displayed IoT does not match the information about the updated current state in the first server, displaying the updated information about the IoT current state through the display.
