In-Vehicle Chat Control for Real-Time Ride Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing onboard services lack convenience in terms of communication and interaction between users and vehicle operators, particularly in providing real-time messaging and control signals during a ride.
Innovation Solution
A control system and method that enables users to transmit and receive messages through a chat function with a registered chatting partner associated with the vehicle, using a control device and communication unit to generate and send control signals based on user inputs, enhancing the onboard service experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a chat function is provided for transmitting and receiving messages between the user and a registered chatting partner, then communication convenience is improved, but device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates between the user terminal and the vehicle terminal. The server handles message routing, partner matching, and communication coordination, thereby implementing the chat function without increasing the complexity of the terminal devices themselves. This resolves the contradiction by externalizing the complex communication logic to a dedicated intermediary system.
Solution Approach 2:
The server is designed as a universal platform that handles multiple functions including message transmission, partner registration, vehicle allocation coordination, and user management. By consolidating these diverse functions into a single multi-functional server, the system avoids duplicating complex logic across multiple devices, thus improving communication convenience while controlling overall system complexity.
2Speed
If real-time message transmission is enabled between user and vehicle operator, then service responsiveness is improved, but information loss increases due to potential communication errors
Solution Approach 1:
The patent implements a feedback mechanism where the server confirms message delivery and provides status updates to both the user terminal and vehicle terminal. The system tracks message transmission states and can request retransmission if delivery fails, ensuring that information is accurately transmitted in real-time without losing critical communication data.
Solution Approach 2:
The system performs preliminary checks and validations before message transmission, including verifying user authentication, checking message format compliance, and pre-establishing communication channels. This preventive approach cushioning against potential transmission errors and information loss before they occur, while maintaining real-time communication capability.

AI summary
A user terminal is provided with a chat function for transmitting and receiving a message between a user and a registered chatting partner. The user terminal includes a control unit which allows the user, while the user is in a vehicle, to transmit and receive a message to and from a predetermined chatting partner associated with the vehicle.
