Dual Vehicle Terminal Service Sync Without Infotainment Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle terminals require software updates every time service subscription guidance information changes, leading to increased development and maintenance costs, and are unable to provide the latest information without a direct link to a service server.
Innovation Solution
A vehicle system with two terminals, where the first terminal communicates with a service server to obtain and provide service subscription information to the second terminal, allowing the second terminal to determine service subscription status and provide guidance or services based on this information, without requiring software updates on the second terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle terminal stores service subscription guidance information locally and provides guidance based on pre-stored information, then the terminal can provide guidance without direct server connection, but the terminal cannot provide updated guidance information when service subscription policies change
Solution Approach 1:
The system pre-loads service subscription guidance information into the vehicle terminal before the user needs it. The terminal receives and stores subscription information, subscription state information, and guidance information in advance from the server, so that when a service request occurs, the terminal can immediately provide accurate guidance without needing real-time server connection.
2Reliability
If the software of the vehicle terminal is changed every time service subscription guidance information changes, then the terminal can provide the latest information, but development and maintenance costs are increased
Solution Approach 1:
The system separates service subscription guidance information from the terminal's core software. The guidance information is stored as independent data that can be updated and refreshed separately from the terminal's software code. This allows the server to push updated subscription information to terminals without requiring software updates, reducing development and maintenance costs while keeping information current.
3Reliability
If the terminal makes a request to the service server for service subscription information every time a connected car terminal is reset, then the terminal can obtain the latest information, but communication overhead and response time are increased
Solution Approach 1:
The terminal requests and stores service subscription information from the server in advance, before it is actually needed for service guidance. This pre-loading approach ensures that when the terminal is reset or when service requests occur, the information is already available locally, eliminating the need for time-consuming real-time requests and reducing both communication overhead and user-perceived response time.

AI summary
A vehicle, a service providing method thereof, and a vehicle service providing system and method including the same that are realized to provide a service are disclosed. The vehicle includes a first vehicle terminal and a second vehicle terminal. The first vehicle terminal is configured to communicate with a service server and provide the second vehicle terminal with service subscription information received from the service server by request according to a preset situation. The second vehicle terminal is configured to communicate with a content server. The second vehicle terminal is configured to determine whether a service for the vehicle is subscribed to, based on the service subscription information in response to a determination that there is a service request. The second vehicle terminal is configured to provide a connected-car service based on communication with the content server in response to a determination that the service is subscribed to.
