Hybrid Vehicle Energy Flow Display with Module Breakdown Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hybrid vehicle energy flow displaying screens do not provide functionality to display breakdowns and abnormal states of modules, limiting drivers' ability to recognize and prepare for issues.
Innovation Solution
A method and apparatus that process power shift and breakdown state information into graphical icons and text graphics, allowing simultaneous display on a single screen, enabling visualization of energy flow, module status, and alerts for abnormal conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the energy flow displaying screen displays only energy flow state, then the display is simple and clear, but it cannot display breakdowns and abnormal states of modules
Solution Approach 1:
The display screen is designed to perform multiple functions simultaneously: displaying energy flow state, module breakdown status, and abnormal state information. The graphics controller processes and integrates multiple types of information (power shift information, breakdown state information) into a unified display, making the display system universal rather than specialized for a single function.
Solution Approach 2:
The patent combines previously separate display functions into a single integrated screen. The energy flow display and module status display are merged into one visual interface, with icons representing modules and lines representing both energy flow and status indicators. This consolidation eliminates the need for separate displays while providing comprehensive vehicle information.
2Loss of information
If multiple types of information are displayed simultaneously, then driver awareness is improved, but the display screen becomes cluttered and harder to read
Solution Approach 1:
The display information is segmented into distinct visual elements: icons represent individual modules, lines represent energy flow paths, and text graphics indicate breakdown states. Each type of information is visually separated and coded differently, allowing the driver to quickly scan and interpret multiple pieces of information without confusion. The segmentation enables selective attention to different information types based on their visual characteristics.
Solution Approach 2:
The patent uses different colors and visual characteristics to encode different types of information and states. Energy flow lines and module icons can change color or appearance based on their operational state, with specific color codes indicating normal operation, breakdown, or abnormal conditions. This visual coding system allows multiple information types to be displayed simultaneously while maintaining readability through color differentiation.

AI summary
Provided are a method and apparatus for displaying energy flow in a hybrid vehicle. The present invention adds a function, which displays breakdown and abnormal state information on modules and is not provided by an energy flow displaying function of the existing hybrid vehicle, to the energy flow displaying function, thus removing inconvenience of the existing energy flow displaying function that cannot check information on breakdown and abnormal states of a vehicle.
