Vehicle Display Controller Adapting Information for Autonomous Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems, such as head-up displays, are limited in conveying information related to driver safety and vehicle state, especially when autonomous driving functions are engaged, and lack the ability to adapt information display based on driving mode or location grade.
Innovation Solution
A display apparatus with a controller that monitors driving manipulation variables and location grades to select appropriate driving modes, adjusting the type and amount of information displayed on the screen, reducing driving information and increasing convenience information when autonomous driving is engaged or in low-grade areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving function is executed, then driver safety is improved, but information display adequacy deteriorates
Solution Approach 1:
The display apparatus dynamically changes the displayed information based on the current driving mode. When autonomous driving is executed, the display shows convenience information such as navigation, entertainment, and vehicle settings. When manual driving is detected, the display switches to show driving-related information such as speed, fuel level, and warning messages. This dynamic adaptation ensures that the display content is always appropriate for the current driving situation.
Solution Approach 2:
The system changes the parameter of displayed information type based on the driving mode. The controller monitors manipulation variables of driving manipulation devices to determine whether the vehicle is in autonomous or manual driving mode, and accordingly changes the display parameters to show either convenience information or driving information. This parameter change resolves the contradiction by ensuring information adequacy in both driving modes.
2Loss of information
If display shows all driving information, then information completeness is improved, but driver distraction increases
Solution Approach 1:
The display apparatus dynamically adjusts the type of information shown based on driving mode. In autonomous driving mode, comprehensive convenience information is displayed without causing distraction. In manual driving mode, only essential driving information is displayed, reducing distraction while maintaining completeness of necessary information.
Solution Approach 2:
Different types of information are displayed in different driving modes. The system applies local quality by showing convenience information (navigation, entertainment, settings) specifically in autonomous driving mode, and driving information (speed, fuel, warnings) specifically in manual driving mode. This ensures that each driving mode receives the appropriate type of information without unnecessary distraction.
3Ease of operation
If display adapts to driving mode, then driver convenience is improved, but system complexity increases
Solution Approach 1:
The display apparatus automatically determines the driving mode by monitoring manipulation variables of driving manipulation devices without requiring driver input. The system self-adjusts the displayed information based on detected driving mode, eliminating the need for manual switching or complex user configuration. This self-service approach improves convenience while keeping the control logic relatively simple.
Solution Approach 2:
The display apparatus serves multiple functions by adapting to different driving modes. It can display both convenience information and driving information depending on the mode, making it a universal display system that handles various information types. This multi-functionality is achieved through a relatively simple mechanism of monitoring driving mode and switching display content accordingly.

AI summary
A vehicle display apparatus and a method for controlling the same are disclosed. The display apparatus includes a display (170, 172) and a controller (180, 190) configured to monitor a manipulation variable of a driving manipulation device provided to a vehicle, to select any one driving mode corresponding to the manipulation variable of the driving manipulation device from among a plurality of predetermined driving modes, and to control the display to display different information according to the plurality of driving modes. When a driving mode corresponding to a relatively small manipulation variable is selected, the controller decreases driving information displayed on the display and increases convenience information displayed on the display, as compared to when a driving mode corresponding to a relatively large manipulation variable is selected.
