Server-Mediated Occupant Association for Vehicle Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle data provision systems require numerous procedures for short-range communication between on-board devices and terminals, leading to a heavy load on both devices and inefficient occupant determination processes.
Innovation Solution
A server device with an on-board device information acquisition unit, a terminal request unit, and an occupant determination unit that transmits riding determination requests to multiple terminal devices, associating them with on-board devices based on responses within a predetermined distance and movement criteria, reducing the need for direct device connections and streamlining the occupant determination process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If short-range communication is used to connect on-board devices and terminal devices for occupant determination, then occupant management can be achieved, but the processing load on devices increases due to numerous procedures such as signal acknowledges and pairing
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates between on-board devices and terminal devices. The server receives position information from on-board devices and response information from terminal devices, then performs the association processing centrally. This eliminates the need for direct short-range communication and pairing procedures between on-board and terminal devices, significantly reducing device complexity while maintaining reliable occupant determination through server-based position matching.
2Speed
If direct short-range communication is established between on-board devices and terminal devices, then real-time occupant information can be obtained, but the system imposes heavy load on both on-board devices and terminal devices
Solution Approach 1:
The server acts as a central intermediary that handles all communication processing. On-board devices only need to send position information to the server, and terminal devices only need to respond to server requests. This distributes the processing load to the server infrastructure rather than burdening resource-constrained on-board and terminal devices, reducing their energy consumption while maintaining real-time occupant information acquisition through efficient server-mediated position matching.
3Reliability
If multiple procedures are required for device connection and pairing, then secure communication can be established, but the occupant determination process becomes inefficient and time-consuming
Solution Approach 1:
The server serves as a trusted intermediary that centralizes all authentication and association logic. Position information from on-board devices and response information from terminal devices are both processed by the server, which performs the association determination. This eliminates the need for time-consuming direct pairing procedures while maintaining security through server-based verification, significantly improving occupant determination efficiency without compromising communication reliability.

AI summary
An object is to provide a server device, an occupant determination method, and an occupant determination support method that efficiently manages an occupant to be associated with a vehicle. A server device includes an on-board device information acquisition unit configured to acquire position information from an on-board device, a terminal request unit configured to transmit, to a plurality of predetermined terminal devices, information indicating a riding determination request including the position information of the on-board device, and an occupant determination unit configured to associate at least one terminal device out of the plurality of predetermined terminal devices and the on-board device with each other, based on a response from the terminal device that is present within a predetermined distance from the on-board device.
