Vehicle Boot Display Control with Configuration-Based Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle boot display technologies are limited in their ability to dynamically adapt display modes based on vehicle configuration, resulting in unsatisfactory visual effects during startup.
Innovation Solution
A method and system for controlling boot display that acquires vehicle configuration information, determines a display mode, and drives screens to display videos or pictures accordingly, utilizing multiple threads and players to synchronize or delay animations across multiple screens for enhanced visual effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If video mode is used for boot display, then visual effect and user experience are improved, but system resource consumption and processing complexity increase
Solution Approach 1:
The system pre-loads video resources and pre-initializes players before boot display is needed. Configuration information is read in advance to determine whether video mode is supported, allowing the system to prepare appropriate resources beforehand rather than dealing with complexity during the actual boot process.
Solution Approach 2:
The system changes operational parameters dynamically based on configuration information. When video mode is determined to be unsupported or unavailable, the system switches from video playback parameters to picture display parameters, thereby adapting to system capabilities and avoiding unnecessary complexity.
2Illumination intensity
If multiple screens are used for boot display, then visual effects and user experience are improved, but system resource consumption increases
Solution Approach 1:
The system divides the boot display task into separate segments for each screen. Each screen has its own dedicated player and thread, allowing independent control and resource management. This segmentation enables the system to efficiently allocate resources to each screen without requiring all screens to consume maximum resources simultaneously.
Solution Approach 2:
The system implements a fallback mechanism where if video mode is not supported on all screens, it automatically switches to picture mode for those screens. This partial action principle ensures that the system uses video playback only where supported, avoiding unnecessary resource consumption on screens that cannot display video.
3Adaptability or versatility
If configuration information is read and determined, then display mode adaptation is improved, but processing time increases
Solution Approach 1:
The system reads and determines configuration information during the initialization phase, before the actual boot display is rendered. This preliminary determination of video vs. picture mode allows the system to prepare the appropriate display pipeline in advance, minimizing the time added to the actual boot process.
4Reliability
If thread connection detection is implemented, then display reliability is improved, but system complexity increases
Solution Approach 1:
The system implements a feedback mechanism where each thread continuously monitors its connection status to the screen. Based on this feedback, the system can dynamically switch between video and picture modes for each screen independently. This feedback-driven approach improves reliability by ensuring that each screen displays content appropriate to its current state.

AI summary
Provided is a method for controlling boot display. The method includes: acquiring configuration information of a vehicle in response to receiving a start-up signal of the vehicle; determining a display mode matching the configuration information; acquiring a boot animation corresponding to the display mode; and driving a screen of the vehicle to display the boot animation in accordance with the display mode.
