Solution Overview

Problem

Modern vehicles face challenges in displaying critical vehicle-specific parameters in a way that allows drivers to quickly and intuitively perceive them, especially when faced with overwhelming information in multifunction operating and display devices, leading to potential distractions and decreased reaction times.

Innovation Solution

A method and device that display a critical value range of a first vehicle-specific parameter by using a scale divided into parts, where the current value is graphically represented, and when reaching a predefined critical value, the scale part is marked, and related parameters are displayed, with visual changes such as color, luminosity, or movement to draw attention, allowing for intuitive detection of critical conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If comprehensive information is displayed in the combination instrument, then the driver can perceive information without taking eyes off the road, but the driver cannot grasp desired information quickly and becomes distracted

Engineering Contradiction:
Improveinformation perceptionVSAvoidinformation processing speed
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display area is segmented into multiple regions: a first display area for primary driving information and a second display area for additional information. This segmentation allows the driver to access comprehensive information while keeping critical driving information prominently visible, preventing distraction by organizing information hierarchy spatially

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the display are assigned different visual characteristics and information types. The first display area uses high visibility characteristics for critical information, while the second display area provides supplementary information with adjusted visual properties, allowing rapid identification of desired information based on location and visual cues

Inventive Principle:
Principle #3Local quality

2Reliability

If more information is displayed to the driver, then comprehensive monitoring is improved, but reaction time decreases due to information overload

Engineering Contradiction:
Improvemonitoring capabilityVSAvoidreaction time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Critical information is pre-positioned in the first display area within the primary field of vision, so that when the driver needs to react, the most important information is already visible without requiring search or attention shifting. Supplementary information is placed in the second display area for later review

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Information is extracted and separated into two categories: critical driving information placed in the first display area and supplementary information placed in the second display area. This extraction ensures that reaction-critical information is isolated and immediately accessible, preventing information overload from affecting reaction time

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The invention relates to a method for displaying a critical value range of a first vehicle-specific parameter in a vehicle (1), wherein the current value of the first parameter is determined. In an area (26) on a display surface (7), at least one scale (27), which displays possible values ​​of the first parameter and which is subdivided into several scale segments (27.1 to 27.8), and a graphic element (28), which displays the current value of the first parameter on the scale (27), are displayed. Furthermore, when the first parameter has reached a predefined critical value, the area (26) of the display surface (7) is controlled such that at least one scale segment (27.1) of the scale is changed so that the scale segment (27.1) is at least partially marked as the critical value range of the first parameter.Furthermore, the invention relates to a device (3) for displaying a critical value range of a first vehicle-specific parameter in a vehicle (1).
