Reconfigurable Cockpit Controller Interface for Head-Unit Upgrades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automotive systems face challenges in upgrading cockpit domain controllers due to limited standardization of interfaces, leading to costly modifications and loss of user preferences when replacing head-units, and a lack of available ports for additional subsystems, which restricts the incorporation of new features and systems.
Innovation Solution
A scalable connectivity architecture is introduced, allowing for modular and reconfigurable interfaces that enable seamless head-unit upgrades by transferring user settings and authenticating new units, while also providing additional ports through modular headers and compute modules, accommodating various subsystems without requiring hardware replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional non-standardized interfaces are used in cockpit domain controllers, then hardware modifications are required for upgrades, but this increases upgrade costs and complexity
Solution Approach 1:
The patent implements a standardized interface architecture that allows a single interface design to support multiple head-unit models and future upgrades without requiring hardware modifications. The generic car-interface defines universal connection protocols and physical interfaces that work across different infotainment systems, enabling upgrades while maintaining the same hardware platform.
2Adaptability or versatility
If more ports are added to accommodate additional subsystems, then connectivity is improved, but circuit board space and housing size increase
Solution Approach 1:
The patent segments the connectivity architecture into modular components including reusable communication buses (CAN, Ethernet, LIN) that can be dynamically configured for different subsystems. This segmentation allows the same physical ports to serve multiple functions through software configuration rather than requiring dedicated physical ports for each subsystem, thereby reducing circuit board space while maintaining comprehensive connectivity.
3Ease of operation
If user settings are not preserved during head-unit replacement, then installation is simplified, but user experience deteriorates due to loss of preferences
Solution Approach 1:
The patent implements preliminary data backup and transfer mechanisms that automatically preserve user settings during head-unit replacement. The standardized interface includes protocols for exporting user preferences, configuration data, and personal information before the old head-unit is removed, and automatically importing these settings to the new head-unit, thereby maintaining user experience while simplifying the physical replacement process.

AI summary
Embodiments are disclosed for a standardized car interface for cockpit controllers in vehicles. In one example, a system for coupling a vehicle cable for communication with components of an infotainment system, comprises: a housing, a domain controller, and a first connector interface including all connections for the domain controller. In the event that a first domain controller is exchanged for a second domain controller, a collection of user preferences may be transferred between the first domain controller to the second domain controller.
