Vehicle Display Region Management for Flexible Screen Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing on-vehicle systems and display apparatuses lack efficient management and allocation of display regions across multiple displays, leading to suboptimal utilization and user experience.
Innovation Solution
A display control device and system that manages multiple display regions within a vehicle, allowing external terminals to request and utilize specific display regions based on a display region table, which includes information on identifiers, positions, sizes, modes, and usage conditions, enabling efficient allocation and display of terminal and vehicle application images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple displays are provided in a vehicle with multiple display regions, then the display capacity and information presentation capability are improved, but the management complexity and allocation difficulty of display regions increase
Solution Approach 1:
The patent segments the multiple displays into distinct display regions, each with unique identifiers and attributes. The display region manager divides the management task by creating separate region profiles that can be independently controlled, allocated, and monitored, thus reducing the overall management complexity while maintaining high display capacity
Solution Approach 2:
The patent introduces a display region manager as an intermediary component between the external terminal and the multiple display regions. This manager handles the complex allocation, assignment, and control operations, shielding the terminal from the underlying complexity while enabling efficient utilization of multiple display regions
2Adaptability or versatility
If external terminals can freely access and display on any display region, then the flexibility and user experience are improved, but the control and management overhead increase
Solution Approach 1:
The patent implements dynamic display region allocation where the display region manager can assign, reassign, and release display regions based on real-time terminal requests and system state. This dynamic management approach provides high flexibility for different usage scenarios while maintaining centralized control to manage complexity
Solution Approach 2:
The patent changes the state parameters of display regions (such as assignment status, terminal association, and display mode) based on manager decisions and terminal requests. By managing regions through parameter changes rather than physical reconfiguration, the system achieves flexibility while keeping control logic manageable

AI summary
A display control device used in a vehicle provided with a display that includes a plurality of display regions. The display control device includes a display region manager that manages the plurality of display regions. When the display region manager obtains, from an external terminal, a display request for displaying display data on a display region included in the plurality of display regions, the display region manager creates a display region table collectively indicating display region information on at least one display region among the plurality of display regions, and outputs the display region table to the external terminal.
