Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing rate of traffic accidents caused by using mobile phones while driving necessitates a method to reduce distractions and control terminal usage during vehicle operation.
Innovation Solution
A method and device that utilize a telematics module and communication server to recognize vehicle drive conditions, generate notice messages, and control call connections based on driver selection, preventing calls during travel to minimize distractions and accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal allows call connections during vehicle operation, then communication convenience is improved, but the risk of traffic accidents increases due to driver distraction
Solution Approach 1:
The system performs preliminary detection of vehicle operation state before allowing call connections. The terminal controller detects whether the vehicle is being operated through vehicle status signals (ignition status, speed signals from ECU) before the call connection is established, preventing calls during active driving conditions
Solution Approach 2:
The terminal controller acts as an intermediary between the communication function and the vehicle operation state. It receives vehicle status information from the ECU, processes this information to determine operational state, and based on this determination, controls whether call connections are permitted, thus mediating between communication needs and safety requirements
2Object-affected harmful factors
If the terminal control device actively monitors and controls call connections, then traffic safety is improved, but device complexity increases due to additional monitoring functions
Solution Approach 1:
The terminal controller performs multiple functions: it serves as both the communication control device and the vehicle operation state monitor. By integrating the vehicle status detection, processing, and call control functions into a single controller, the system achieves safety monitoring without adding separate dedicated monitoring devices, thus reducing overall system complexity
Solution Approach 2:
The terminal controller utilizes existing vehicle bus systems and ECU data outputs to obtain operation status information without requiring separate sensors or monitoring hardware. The system self-services by leveraging already-available vehicle digital infrastructure (CAN bus, ECU data streams) to perform safety monitoring functions

AI summary
A communication server in cooperation with a telematics center receives a result message for condition guidance service selection result information from the telematics center to control a driver terminal according to traveling condition recognition of a vehicle, stores a driver terminal number, call control request information during traveling, and condition notice information during traveling included in the result message, sets a condition guidance service, and controls call connection with a call connection attempting terminal for attempting a call connection to the driver terminal according to a type of the result message.
