Adaptive Cockpit Display Layout for Forward Vision in Low Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cockpits require improved techniques to handle digital displays in an integrated manner, particularly in changing layouts according to different display modes to enhance driver and passenger convenience while ensuring forward vision and safety.
Innovation Solution
A cockpit system with a front display that includes multiple display areas, a controller for movement and tilting, and a see-through panel to provide simplified information through the lower area during a low mode, featuring a dead front effect and adjustable interfaces to maintain visibility and functionality.
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 driving safety is improved, but the display area visible to the driver is reduced
Solution Approach 1:
The display system is segmented into multiple independent display areas (first display area, second display area, third display area) that can be independently controlled and activated. This allows the system to provide information through different segments depending on the display mode, resolving the contradiction by using the first display area for driver information when safety is prioritized.
Solution Approach 2:
Different display areas are assigned different functions and qualities based on their location. The first display area (lower area) is optimized for driver visibility and safety-critical information, while other areas serve different purposes. This local differentiation allows the system to maintain adequate display functionality while prioritizing driver safety.
2Adaptability or versatility
If multiple display areas are provided in the front display, then information provision capability is improved, but device complexity increases
Solution Approach 1:
The front display is designed as a multi-functional unit that can operate in different modes (standard mode, low mode, tilt-back mode) and provide information to different users (driver, front passenger, rear passengers) depending on the activation state of different display areas. This universal design allows one display structure to serve multiple purposes, reducing the need for separate dedicated displays for each function.
Solution Approach 2:
The display system dynamically adjusts which display areas are activated based on the current display mode and user needs. The controller selectively activates or deactivates different display areas according to the operating conditions, allowing the system to adapt its complexity level to the current situation rather than maintaining maximum complexity at all times.
3Ease of operation
If the front display is tilted backward in tilt-back mode, then passenger comfort is improved, but driver's forward vision may be compromised
Solution Approach 1:
The display is segmented into multiple independent areas that can be tilted at different angles or deactivated independently. When tilt-back mode is activated for passenger comfort, the system can selectively tilt or deactivate the second display area (front passenger area) while maintaining the first display area (driver area) in a position that does not obstruct the driver's forward vision.
Solution Approach 2:
Different portions of the display are assigned different tilt characteristics based on their function. The driver-oriented display areas maintain a tilt angle optimized for driver visibility and safety, while passenger-oriented areas can be tilted back for passenger comfort. This local quality differentiation resolves the contradiction by allowing simultaneous optimization for both driver safety and passenger comfort.

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.
