Vehicle Display Layout for Map and Road Condition Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems do not effectively integrate map information and road condition recognition to support user understanding of vehicle control, particularly in advanced driving assistant systems (ADAS).
Innovation Solution
A vehicle display control device that sets a first display area for a map of the vehicle's surroundings and a second display area for the road condition, adjusting their sizes based on driving assist system operation and driver state, to enhance user comprehension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If both map information and road condition recognition results are displayed together, then user understanding of vehicle control is improved, but display processing load increases
Solution Approach 1:
The display screen is divided into multiple regions: a first region displaying map information and a second region displaying road condition recognition results. This segmentation allows both types of information to be presented simultaneously without overwhelming the display system, as each region can be optimized independently for its specific data type.
Solution Approach 2:
Different display regions are assigned different information types based on their importance and characteristics. The road condition recognition results (critical for safety) are displayed in a dedicated second region with prominent positioning, while map information occupies the first region. This local differentiation optimizes information presentation without requiring complex processing of all data uniformly.
2Loss of information
If road condition display area is increased to improve understanding, then user comprehension of control is enhanced, but map information visibility is reduced
Solution Approach 1:
The display system dynamically adjusts the allocation of screen space between map information and road condition recognition results based on the operational state of the vehicle. When ADAS is active, the second region for road conditions is expanded; when ADAS is inactive, the first region for map information is prioritized. This dynamic adjustment resolves the contradiction by making the display configuration adaptive rather than static.
Solution Approach 2:
The system displays road condition recognition results with enhanced prominence and size relative to map information when ADAS is operating, using partial action (selective emphasis) rather than displaying all information with equal weight. This allows critical control-related information to dominate the display temporarily without permanently reducing map visibility.
3Loss of information
If multiple information types are displayed simultaneously, then user comprehension is improved, but ease of operation is reduced due to information overload
Solution Approach 1:
The display is segmented into functionally distinct regions with clear visual separation. The first region presents map information in a traditional navigation format, while the second region presents road condition recognition results in a simplified, icon-based, or highlighted format. This segmentation reduces cognitive load by organizing information hierarchically rather than presenting it as a undifferentiated mass.
Solution Approach 2:
The system uses color coding and visual emphasis to differentiate between map information and road condition recognition results. Critical road condition data is presented with distinctive colors, icons, or highlighting that make it immediately recognizable and easier to process than the more detailed but less critical map information, thereby improving ease of understanding.
Data Source
AI summary
A vehicle display control device includes a processor. The processor acquires map information based on a current position of a vehicle. The processor acquires peripheral information of the vehicle. The processor sets, based on the map information and the peripheral information, a first display area that displays a map of an area around the vehicle and a second display area that displays a road condition around the vehicle on a display unit in a vehicle cabin.
