Cloud-Based IVI Virtual Instances for Cross-Vehicle App Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle infotainment systems require dedicated software development for each system and do not allow users to select services based on personal preferences, limiting the use of desired applications.
Innovation Solution
A cloud server system that generates a virtual instance using user account information from an in-vehicle infotainment system, allowing application selection and execution through a cloud manager, enabling the use of mobile or PC applications without separate IVI system software development.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated software is built into the IVI system for each service operator, then the IVI system can provide infotainment services, but service operators cannot provide services without developing dedicated software for each IVI system and drivers cannot select services based on personal preferences
Solution Approach 1:
The patent introduces a cloud server as an intermediary between service operators and the IVI system. The cloud server hosts multiple infotainment services and delivers them to the IVI system over a network, eliminating the need for dedicated software development for each IVI system. Drivers can select from various services provided by different operators through the cloud server, achieving service flexibility without increasing local software complexity.
Solution Approach 2:
The cloud server provides a universal platform that hosts multiple infotainment services from different operators. Instead of requiring each IVI system to have dedicated software for each service, the universal cloud-based platform delivers services to any IVI system through standard communication protocols, enabling one service infrastructure to support multiple functions and operators.
2Adaptability or versatility
If multiple infotainment services are provided through a cloud server, then service operators can provide services without developing dedicated IVI software and drivers can select based on preferences, but the system requires network infrastructure and cloud server resources
Solution Approach 1:
The cloud server acts as an intermediary that consolidates service delivery infrastructure. Instead of each service operator needing direct integration with each IVI system (creating complex point-to-point connections), the cloud server provides a single centralized infrastructure that multiple operators can access, reducing overall system complexity while enabling service flexibility.
3Quantity of substance
If application execution is handled locally in the IVI system, then applications can run directly on the vehicle system, but the system requires dedicated software development for each IVI system and limits application variety
Solution Approach 1:
The cloud server serves as an intermediary that hosts a wide variety of applications and delivers them to the IVI system. This approach provides access to numerous applications without requiring local software development for each application, as the cloud server handles application hosting, management, and delivery through standardized interfaces.
Solution Approach 2:
Instead of installing and developing applications locally on each IVI system, the patent uses cloud-based application copying where applications are hosted on the cloud server and delivered to the IVI system as needed. This allows the same application instance to be shared across multiple IVI systems, reducing development effort while increasing application variety.

AI summary
A cloud server that provides in-vehicle infotainment can include a virtual instance generated using a user account received from an in-vehicle infotainment (IVI) system installed in a vehicle, and when an on operation for starting the vehicle is detected by the IVI system, a cloud manager of the cloud server can be configured to receive information on the user account from the IVI system, search for the virtual instance including the user information matching user information included in the user account, transmit an application list included in the searched virtual instance to the IVI system, receive application selection information specifying at least one application among a plurality of applications included in the application list from the IVI system, execute an application corresponding to the application selection information using the searched virtual instance, and transmit an execution screen of the application to the IVI system.
