Adaptive Cockpit Display Layout for Low-Mode Forward Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles lack an efficient method to adapt cockpit layouts according to different display modes, compromising driver visibility and safety, especially in low-mode conditions.
Innovation Solution
A cockpit system with a front display that includes multiple display areas, a controller for adjusting the display's position and tilt, and a see-through panel to transmit information from the lower area, providing a 'dead front effect' and simplified information in low-mode conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the front display is moved downward in low mode to secure driver's forward vision, then driver safety and forward visibility are improved, but the display area exposed to the driver is reduced
Solution Approach 1:
The display is segmented into multiple display areas (first display area, second display area, third display area) that can be independently controlled. When in low mode, the front display moves downward and the controller selectively activates only the necessary display areas (e.g., third display area for see-through display, first display area for essential information), deactivating others to maintain driver safety while preserving essential display functionality.
Solution Approach 2:
The cockpit layout is made dynamic by allowing the front display to move between different positions (standard mode with display at preset position, low mode with display moved downward). The controller dynamically adjusts which display areas are activated based on the selected mode, enabling the system to adapt its information presentation to the current operational context.
2Use of energy by moving object
If multiple display areas are deactivated to reduce power consumption, then energy efficiency is improved, but the functionality and information availability are reduced
Solution Approach 1:
Different display areas are assigned different functions and activation states based on local requirements. The controller selectively activates specific display areas (e.g., third display area for see-through display in low mode, first display area for essential vehicle information) while keeping others deactivated, ensuring that each active area serves its specific purpose efficiently.
3Reliability
If the front display is moved downward in low mode, then driver's forward vision is secured, but the interface size and visibility on the exposed screen are reduced
Solution Approach 1:
The controller changes the parameters of the display interface by adjusting the size, position, and content of displayed elements based on the active display areas. When in low mode, the interface is reconfigured to match the smaller exposed screen area, ensuring that essential information remains visible and accessible within the constrained display space.

AI summary
A cockpit system with a layout changed according to a display mode in a mobile device includes a front display disposed in front of a driver's seat and a passenger seat of the mobile device, a controller to move the front display upward and downward and to tilt the front display, and a see-through panel to transmit light from a lower area of the front display to provide information to the driver and a passenger, when a low mode among display modes is applied, after the front display is moved downward. The front display includes a display panel including a plurality of display areas, and when at least one of the plurality of display areas is deactivated, a dead front effect is represented to make the deactivated display area indistinguishable from a part other than the deactivated display area.
