Vehicle Display Dual-Level Safety Information Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle cockpits, safety-critical and non-safety-critical information are often displayed together on large screens, leading to the potential oversight of critical safety information due to information overload.
Innovation Solution
The method involves displaying non-safety-critical information in the background and safety-critical information in the foreground on a dual-level display, with adjustments to the safety-critical information's presentation to ensure it remains recognizable even when partially superimposed by non-safety-critical information, using techniques like color, line, size, or contrast changes.

Engineering Contradiction Analysis
1Quantity of substance
If safety-critical and non-safety-critical information are displayed together on a common display unit, then the information density and utilization of the display are improved, but the recognizability of safety-critical information deteriorates due to superimposition and information overload
Solution Approach 1:
The patent introduces a temporal dimension to the display system by implementing multiple display levels with different update frequencies. Safety-critical information is displayed at a higher update frequency (first display level) while non-safety-critical information updates at a lower frequency (second display level). This temporal differentiation allows both types of information to coexist without相互 interference, maintaining the recognizability of safety-critical information while increasing overall information density.
2Reliability
If non-safety-critical information is displayed in the background and safety-critical information in the foreground, then the prioritization of safety information is improved, but the overall information presentation becomes more complex
Solution Approach 1:
The patent implements a dynamic display system where the display unit can switch between different display modes depending on the type of information being presented. The system dynamically adjusts the number of display levels active at any given time - using a single level for safety-critical information and multiple levels when non-safety-critical information needs to be displayed. This dynamic approach maintains clear prioritization while avoiding unnecessary structural complexity.

AI summary
A method for the joint display of safety-critical and non-safety-critical information on a vehicle display unit is described. The method comprises receiving non-safety-critical information and generating at least one graphical representation of this information. Furthermore, the method comprises receiving safety-critical information and generating at least one graphical representation of this information. Finally, the method comprises displaying the presentations of safety-critical and non-safety-critical information on the display unit, wherein the display has at least two representation levels.In this method, the presentation of non-safety-critical information is displayed on a rear of at least two display planes, in the viewer's line of sight, while the presentation of safety-critical information is displayed on a front display plane. The method verifies whether, with at least partial overlap, the presentation of non-safety-critical information can be distinguished from the presentation of safety-critical information, i.e., whether the safety-critical information remains recognizable.
