Mobile Terminal Vehicle Calling System with Real-Time Dispatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle calling services require users to remember phone numbers and pose safety concerns, especially for vulnerable groups like women and the elderly, due to increasing crimes committed by drivers.
Innovation Solution
A method and system that uses a mobile terminal, a vehicle terminal, and a vehicle calling server to facilitate the request and dispatch of vacant vehicles within a predetermined distance, allowing users to select and communicate with available vehicles directly through the terminal, enhancing safety and convenience by eliminating the need to remember phone numbers and providing real-time tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly place phone calls to vehicle calling center, then vehicle dispatch service can be provided, but users must remember phone numbers which increases operational complexity and reduces ease of use
Solution Approach 1:
The mobile terminal automatically performs vehicle search and dispatch functions without requiring user intervention to remember or dial phone numbers. The system self-services the vehicle calling process by using GPS location, automatically querying available vehicles, and initiating communication with drivers through the terminal itself rather than requiring manual phone calls.
2Reliability
If drivers contact users through phone calls, then vehicle dispatch can be coordinated, but safety concerns arise especially for vulnerable groups like women and elderly
Solution Approach 1:
The mobile terminal serves as an intermediary platform between users and drivers. Instead of direct phone calls where drivers can potentially misuse the system, all communication and coordination happen through the terminal's controlled interface. The terminal displays driver information, enables user selection, and manages the dispatch process, creating a transparent and monitored interaction that protects vulnerable users from driver misconduct.
3Ease of operation
If conventional vehicle calling service is used, then vehicle dispatch is possible, but users experience anxiety and unease due to lack of real-time tracking and verification
Solution Approach 1:
The mobile terminal continuously provides feedback to users about vehicle availability, driver location, and dispatch status. The system displays real-time information about selected vehicles and their movement toward the user's location, creating transparency and reducing anxiety. Users receive continuous updates on the dispatch process, eliminating the uncertainty and information loss that cause discomfort in conventional services.

AI summary
A method of calling a vehicle and a mobile terminal for the same are discussed. According to an embodiment, the method includes: requesting vehicle information on each of at least one vehicle, which is located within a predetermined distance from a position of a mobile terminal and is available, from a vehicle calling server; receiving the requested vehicle information from the vehicle calling server; displaying, on a screen of the mobile terminal, a map on which a position of the mobile terminal and the vehicle information are indicated; when certain vehicle information is selected from the displayed map, generating by the mobile terminal a vehicle request for requesting a dispatch of a vehicle corresponding to the selected vehicle information; and transmitting by the mobile terminal the vehicle request to the vehicle calling server.
