Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a telematics system is implemented to enable remote vehicle diagnosis and control, then user convenience and vehicle management capability are improved, but system complexity and cost increase
Solution Approach 1:
The telematics system is divided into three distinct modules: a communication terminal for user interaction, a service providing center for coordination and data management, and a telematics terminal for vehicle diagnosis and control execution. This segmentation allows each module to have specialized functions, reducing overall system complexity while maintaining comprehensive remote vehicle management capabilities.
Solution Approach 2:
The service providing center acts as an intermediary between the communication terminal and the telematics terminal. It receives requests from the user's communication terminal, processes them, and transmits appropriate commands to the vehicle's telematics terminal. This mediator architecture simplifies the interaction complexity by centralizing coordination logic in the service providing center.
2Reliability
If remote vehicle control functions are added to address theft and battery discharge issues, then vehicle security and management effectiveness are improved, but system reliability requirements increase
Solution Approach 1:
The system enables preliminary actions such as remote engine starting, lighting control, and door locking/unlocking before the user physically approaches the vehicle. This is particularly useful for security scenarios (preventing theft) and convenience scenarios (preventing battery discharge by turning off lights remotely). The service providing center coordinates these preliminary actions by transmitting control commands to the telematics terminal based on user requests.
Solution Approach 2:
The system implements feedback mechanisms where the telematics terminal transmits vehicle status information (engine state, door status, lighting status, diagnostic data) back to the service providing center, which then relays this information to the user's communication terminal. This feedback loop ensures users can monitor the effects of their remote control actions and make informed decisions about vehicle management.
Data Source
AI summary
A system and method for controlling a remote vehicle using a telematics system is provided. In the system and method, a communication terminal, such as a personal computer, a PDA (Personal Digital Assistants), a cell phone, and a line telephone set, is connected to a service providing center of the telematics system to diagnose and check a status of a vehicle equipped with a telematics terminal, thereby controlling functions of the vehicle.
