Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of vehicle systems with multiple devices and software leads to ambiguity in control processing, potentially increasing the risk of driving obstruction due to device control.
Innovation Solution
A method for controlling vehicle virtualization structure-based devices that determines device usage based on the type of device and container requesting use, including checks for public and individual devices, and containers performing vehicle operations, to ensure safe and customized access without interfering with driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices and software are allowed in the vehicle system to increase user freedom and device functionality, then the degree of freedom in using devices increases, but the control processing becomes ambiguous and the risk of driving obstruction increases
Solution Approach 1:
The patent segments the vehicle system into isolated container environments (first container for vehicle operation, second container for infotainment) that run on separate virtual machines. This segmentation allows multiple devices and software to operate simultaneously with different access permissions, preventing control ambiguity while maintaining driving safety through architectural isolation.
Solution Approach 2:
The patent introduces a gateway as an intermediary component between the first container (vehicle operation) and second container (infotainment). The gateway mediates device access requests, controlling which devices can access which containers based on predefined policies. This intermediary mechanism resolves the contradiction by enabling versatile device usage while maintaining strict control over critical vehicle operations.
2Adaptability or versatility
If device access is allowed from multiple containers to increase functionality, then device versatility improves, but control processing ambiguity increases
Solution Approach 1:
The system segments device access control into distinct container boundaries with predefined access rules. Each container (vehicle operation, infotainment) has explicit access permissions to specific devices, eliminating control processing ambiguity. The segmentation approach allows flexible device access within each container while maintaining clear, manageable control boundaries.
Solution Approach 2:
The gateway provides universal access control functionality that serves multiple containers and devices through a single standardized interface. Rather than implementing separate control mechanisms for each container-device pair, the gateway offers multi-functional access management, reducing overall control processing complexity while maintaining access flexibility.
3Ease of operation
If infotainment container has full device access to improve user experience, then device functionality increases, but driving obstruction risk increases
Solution Approach 1:
The patent applies local quality by granting the infotainment container (second container) full device access rights specifically for non-critical functions like media playback and entertainment, while the vehicle operation container (first container) retains exclusive access to critical devices. This localized access policy improves infotainment functionality without compromising driving safety, as each container receives appropriate access rights for its specific purpose.
Solution Approach 2:
The gateway acts as an intermediary that enforces access policies between containers and devices. It allows the infotainment container to access devices needed for user experience (audio, display) while blocking access to devices that could cause driving obstruction (steering wheel controls, brake systems). The gateway mediates access requests based on container identity and device criticality, resolving the contradiction between accessibility and safety.
