Vehicle Display Synchronization Switching for Multi-Region Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle display systems with multiple display regions, synchronization can be inconvenient for occupants, as it either requires constant synchronization or lacks it entirely, failing to provide optimal viewing experiences.
Innovation Solution
A vehicle display system with a switching controller that allows switching between synchronous and asynchronous modes, maintaining a predetermined image in the synchronization source during mode changes, enabling occupants to choose when to synchronize or desynchronize display contents between regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple display regions are always synchronized, then information consistency is improved, but flexibility and user convenience deteriorate
Solution Approach 1:
The system dynamically switches between synchronous and asynchronous display modes based on operational context. The switching controller changes the display mode from synchronous (where both regions show identical navigation information) to asynchronous (where regions can display different information types), providing adaptability while maintaining information consistency when needed.
Solution Approach 2:
The system changes the synchronization parameter of the display regions. When switching to asynchronous mode, the synchronization parameter is adjusted to allow independent content display in each region, while maintaining the ability to restore synchronous mode for information consistency, thus resolving the contradiction between reliability and adaptability.
2Adaptability or versatility
If multiple display regions are always asynchronous, then user customization is improved, but information consistency and coordination deteriorate
Solution Approach 1:
The system provides dynamic control over display synchronization, allowing users to switch between synchronous and asynchronous modes. This dynamic capability enables customization when needed while preserving information consistency through the synchronous mode, resolving the contradiction between adaptability and reliability.
Solution Approach 2:
The display system is designed to perform multiple functions: it can operate in synchronous mode for coordinated information display and in asynchronous mode for customized content presentation. This multi-functionality allows the same system to satisfy both information consistency requirements and user customization preferences.
3Adaptability or versatility
If display mode switching is added, then flexibility is improved, but system complexity increases
Solution Approach 1:
The switching controller is integrated with the existing display controller to manage multiple display regions. By merging the synchronization control and mode switching functions into a unified control architecture, the system achieves flexibility without proportionally increasing complexity.
Solution Approach 2:
The system automatically manages the complexity of mode switching through predefined synchronization protocols and automatic coordinate calculation. When switching between modes, the system self-adjusts the display parameters and synchronization states, reducing the operational complexity for users while maintaining the flexibility benefit.

AI summary
A vehicle display system includes display regions, a display controller and a switching controller. The display controller controls respective displayed contents of the display regions. The switching controller executes switching between a synchronous mode and an asynchronous mode, and executes switching to the synchronous mode while continuing to show a predetermined image in a synchronization source being one of the display regions by maintaining a display setting of the synchronization source. The synchronous mode is a mode in which the displayed contents are synchronized, and the asynchronous mode is a mode in which the displayed contents are not synchronized. The synchronization source is one of the display regions.
