Hybrid Vehicle Display Instrument Boost Mode Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hybrid vehicle drivers lack effective feedback on the current and expected operating state of the drive source, particularly in boost mode, which can impact driving decisions and safety.
Innovation Solution
A display instrument with multiple zones shows the current operating state of the internal combustion engine and electric motor, including the remaining time and power that can be produced in boost mode, using a combination of pointers and light elements for clear visualization, with the option to display power and time in a two-dimensional format and adjust based on battery temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional information zones are added to display boost mode duration and power, then information completeness is improved, but display instrument size increases
Solution Approach 1:
The patent combines the display of boost mode duration and power information within a single shared zone on the display instrument. The control unit dynamically adjusts the presentation of these two parameters within the same spatial region, allowing both pieces of information to be conveyed without requiring separate dedicated zones, thus avoiding an increase in overall display instrument size while maintaining information completeness.
2Loss of information
If multiple parameters are displayed simultaneously, then driver feedback quality is improved, but display complexity increases
Solution Approach 1:
The display instrument employs dynamic display characteristics where the presentation of multiple parameters (boost mode duration and power) is adjusted in real-time based on current operating conditions. The control unit dynamically controls which parameters are displayed, how they are presented, and their visual prominence, allowing complex information to be conveyed through dynamic rather than static means, thereby reducing overall display complexity while maintaining feedback quality.

AI summary
A device for displaying information in a hybrid vehicle comprises a display instrument that has multiple zones for displaying the current operating state of a combustion engine and of at least one electric motor in the hybrid vehicle. The power that the at least one electric motor can generate in a boost mode can be displayed in one of the zones. The display instrument includes a zone that can display the remaining time during which the at least one electric motor can be operated in the boost mode.
