Vehicle Energy Flow Display Using Bridged Transmission Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle energy flow display systems are overly complex due to the large number of icons used, making it difficult for drivers to understand the energy flow in a straightforward manner.
Innovation Solution
An information display apparatus for vehicles that includes a battery icon, wheel icon, and an energy transmission state displaying portion directly bridged between them, indicating the energy transmission state, presence/absence, and direction of energy transfer, with dynamic display changes over time to distinguish between electric power and driving force energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple icons representing engine, motor, battery, and tires are displayed to show energy flow, then the energy transmission information is comprehensive, but the display becomes complicated and difficult to understand
Solution Approach 1:
The patent extracts and displays only the essential energy transmission information between battery and wheels, omitting unnecessary intermediate components. The energy transmission state displaying portion shows only the critical path of energy flow, removing complex icons for engine, motor, and other components that clutter the display while preserving the core energy transmission message.
Solution Approach 2:
Instead of displaying all possible energy transmission paths through multiple icons, the patent inverts the approach by showing only the direct battery-to-wheels energy transmission. This simplified view reverses the conventional detailed display method to achieve clarity without information loss.
2Measurement precision
If detailed energy flow paths are displayed, then the transmission state is accurately represented, but the driver's understanding becomes difficult
Solution Approach 1:
The patent extracts the essential energy transmission state information and presents it in a simplified visual format. The energy transmission state displaying portion shows only the critical states (charging, discharging, power transmission) without detailed intermediate steps, making it both accurate and easily understandable for drivers.
Solution Approach 2:
The patent applies different display characteristics to different energy transmission states. The energy transmission state displaying portion changes its visual properties (such as arrow direction, icon illumination) depending on the specific state, providing precise information while maintaining simplicity through context-appropriate visual cues.

AI summary
An information display apparatus for a vehicle which is advantageous in displaying an energy flow in an easy-to-understand way to the driver is provided. A battery icon represents a driving battery. An engine icon represents an engine. A front-wheel icon and a rear-wheel icon represent front wheels and rear wheels, respectively. An energy transmission state displaying portion indicates the transmission state of energy and is displayed while being directly bridged between the battery icon, the engine icon, the front-wheel icon, and the rear-wheel icon. The energy transmission state displaying portion indicates the presence or absence and the direction of transmission of energy between the driving battery, the engine, the front wheels, and the rear wheels.
