Automatic Text Response System for Driving Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hands-free devices for vehicles do not support text messaging, leaving drivers unable to respond to messages safely while driving, as they are restricted from using their mobile phones.
Innovation Solution
A system and method that automatically determines if a vehicle is in motion and responds to incoming text messages by sending either a fixed or customized message based on pre-set groups and vehicle information, using a mobile communicator and short-range communication with vehicle-mounted devices to manage responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a driver uses a mobile phone to send text messages while driving, then communication responsiveness is improved, but driving safety deteriorates
Solution Approach 1:
The system enables the mobile terminal to automatically generate and send response messages without requiring the driver's direct intervention. The terminal itself performs the messaging function by detecting vehicle state information and autonomously composing appropriate responses, thereby eliminating the need for manual phone operation while maintaining communication capability
Solution Approach 2:
The vehicle state information serves as an intermediary that mediates between the driver and the messaging function. By using vehicle state data (such as speed, location, and destination) as the basis for generating responses, the system creates an indirect communication path that does not require the driver to directly operate the phone, thus maintaining safety while enabling communication
2Object-affected harmful factors
If a hands-free device is used for voice calls while driving, then driving safety is improved, but text messaging capability is lost
Solution Approach 1:
The system makes the mobile terminal universally applicable for both voice calls and text messaging functions while driving. By integrating vehicle state detection with automatic message generation capabilities, the terminal can handle multiple communication types (voice and text) under the same safety framework, eliminating the limitation where hands-free devices only support voice calls
3Productivity
If automatic response messages are sent while driving, then communication efficiency is improved, but message customization is reduced
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple response message templates before driving begins. These templates are prepared in advance and stored in the terminal, allowing the system to quickly select and send appropriate responses during driving without requiring real-time composition, thus maintaining both efficiency and a degree of customization
Solution Approach 2:
The system dynamically selects and adapts response messages based on real-time vehicle state information. Rather than using fixed static responses, the system adjusts the content of automated responses according to current driving conditions (speed, location, destination), making the communication both efficient and contextually appropriate

AI summary
A method for transmitting a text message includes receiving, by a mobile communicator, the text message from an external terminal. Whether a vehicle is being driven is determined by a controller based on vehicle information including vehicle speed information. Whether a user of the external terminal is included in a first reply group is determined by the controller when the vehicle is being driven. Whether the user of the external terminal is included in a second reply group is determined by the controller when the user of the external terminal is included in the first reply group. A fixed response message is transmitted to the external terminal by the controller when the user of the external terminal is not included in the second reply group.
