Hybrid Vehicle Display Device for Boost Duration Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle display devices for hybrid vehicles do not provide sufficient information to drivers about the available boost duration during electromotive boosting, limiting efficient operation.
Innovation Solution
A display device that shows both the total available boost duration in standby mode and the remaining boost duration during active boosting, allowing drivers to make informed decisions about using electromotive boosting based on the displayed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display device shows only the operating mode selected by the driver, then the display is simple and clear, but the driver lacks information about available boost duration for efficient operation
Solution Approach 1:
The display device segments information presentation by showing different boost duration data (total available boost duration vs. remaining boost duration) based on the actuation pattern detected. This allows comprehensive information provision while maintaining display clarity through context-appropriate information selection.
Solution Approach 2:
The display content dynamically changes based on the actuation pattern of the boost selection element. The control device detects whether a first or second actuation pattern occurs and accordingly displays either total boost duration or remaining boost duration, making the information provision adaptive to driver intent.
2Productivity
If the display device provides comprehensive information about boost duration, then driver operation efficiency improves, but the display device complexity increases
Solution Approach 1:
The control device implements feedback by detecting the actuation pattern of the boost selection element and adjusting the displayed information accordingly. This feedback mechanism ensures that the driver receives appropriate information (total or remaining boost duration) based on their interaction pattern, optimizing operation efficiency without requiring complex additional hardware.
Solution Approach 2:
The system uses the driver's own actuation patterns to determine what information to display. The boost selection element's actuation pattern serves as the input that automatically triggers the appropriate information display, eliminating the need for additional complex controls or interfaces.
3Ease of operation
If the display shows total boost duration in standby mode, then the driver can make informed decisions about boosting activation, but the display must differentiate between standby and active boosting states
Solution Approach 1:
The display dynamically adapts its content based on the detected actuation pattern. The control device monitors the boost selection element's actuation characteristics and switches between displaying total boost duration (first pattern) and remaining boost duration (second pattern), making state differentiation automatic and intuitive.
Solution Approach 2:
The system changes the displayed parameter (from total boost duration to remaining boost duration) based on the actuation pattern detected. This parameter change provides clear visual feedback to the driver about the current system state and available resources, facilitating easier decision-making.

AI summary
The invention relates to a display device (10) of a motor vehicle, by means of which an operating mode of a hybrid vehicle can be displayed, namely at least one of the operating modes of purely electric-motor driving and/or purely internal-combustion-engine driving and/or combined electric-motor and internal-combustion-engine driving and, as a special case of the combined electric-motor and internal-combustion-engine driving, electric-motor boosting, wherein an available boost duration can be displayed when the operating mode of electric-motor boosting is displayed.
