In-Vehicle Gateway Central Controller for Subsystem Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle systems have isolated ADAS, communication, and entertainment features, leading to duplicative functions, increased costs, and difficulties in control, management, and maintenance due to the lack of a centralized control system architecture.
Innovation Solution
An in-vehicle gateway system with a central controller and switch fabric that integrates and manages multiple subsystems, enabling resource sharing, data utilization, and unified control commands for scalable and flexible management of ADAS, V2V, V2I communications, and new applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If in-vehicle subsystems are isolated and individually built, then each subsystem can be developed independently, but duplicative functions occur, costs increase, and control, management, and maintenance become difficult
Solution Approach 1:
The patent merges multiple isolated in-vehicle subsystems (ADAS, communications, entertainment, V2V, V2I) into a unified gateway system with a central controller. This consolidation eliminates duplicative functions and reduces overall system complexity while maintaining the ability to develop individual subsystems independently through modular architecture.
Solution Approach 2:
The gateway system implements a universal central controller that manages multiple subsystems through a common interface and shared resources. This multi-functional approach allows a single control unit to handle diverse subsystems, reducing the need for separate control mechanisms and simplifying system management.
2Ease of operation
If a centralized control system architecture is implemented, then control, management, and maintenance are simplified, but system complexity increases initially
Solution Approach 1:
The gateway system is segmented into modular components including the central controller, communication interfaces, and subsystem modules. This segmentation allows the complex centralized architecture to be built from manageable, independent modules that can be developed, tested, and maintained separately, reducing the perceived complexity during implementation.
Solution Approach 2:
The central controller acts as an intermediary between various subsystems and external communication interfaces. This mediator role simplifies control and management by providing a single point of coordination, while the intermediary nature allows gradual integration of subsystems, managing architectural complexity through staged implementation.
3Adaptability or versatility
If new features and applications are added to the system, then system functionality and versatility improve, but development efforts and system changes increase
Solution Approach 1:
The gateway system employs a dynamic architecture where the central controller can adapt to new subsystems and applications through configurable software modules and standardized interfaces. This dynamic design allows new features to be integrated without hardware changes, reducing development efforts while maintaining high versatility and scalability.

AI summary
An in-vehicle gateway system for monitoring and controlling a plurality of in-vehicle subsystems is disclosed. The in-vehicle gateway system includes a central controller and the central controller is configured to enable one of the in-vehicle subsystems to use a resource of another in-vehicle subsystem. The central controller is also configured to enable one in-vehicle subsystem to use data from yet another in-vehicle subsystem. The one in-vehicle subsystem may be a newly added in-vehicle subsystem. The in-vehicle gateway system also includes a switch fabric that is configured to interconnect the central controller to the plurality of the in-vehicle subsystems and transmit at least a unified control command to at least one of the in-vehicle subsystems.
