Steering Wheel Display Layout for Intuitive Left-Right Switch Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular display systems face challenges in improving occupant usability, particularly in discerning operation switches on a steering wheel, as displaying images of both sides simultaneously occupies a large display region and can be confusing.
Innovation Solution
A vehicular display control device that detects operations on right-side and left-side regions of the steering wheel and displays corresponding images in dedicated areas of the display region, allowing for a wider display area and intuitive identification of the operation region by positioning images accordingly, such as moving central images to make room for larger operation region images and using animations to indicate the correct region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If images of both left and right operation switches are displayed on the display screen, then complete information is provided, but a large display region is required and occupant usability deteriorates
Solution Approach 1:
The display region is segmented into multiple areas (first area, second area, third area) corresponding to different operation regions. Instead of displaying all operation switch images simultaneously in one location, the system divides the display space and presents images of operation switches from different sides (left and right) in their respective designated areas, enabling complete information presentation while maintaining clear spatial organization and usability.
2Area of stationary object
If only images of operation switches on one side are displayed, then display region is reduced, but it becomes difficult to discern which operation switches are being displayed
Solution Approach 1:
The display region is divided into distinct segmented areas where each area corresponds to a specific operation region (left or right side). This segmentation allows the system to display images of operation switches from one side at a time in appropriate areas, reducing overall display complexity while maintaining clear identification of which operation switches are active through spatial positioning.
Solution Approach 2:
Different areas of the display region are assigned different functions and display characteristics. The first area displays images from one operation region while the second area displays images from another operation region. This local differentiation enables the system to reduce overall display region requirements while maintaining information clarity through context-appropriate positioning.
3Loss of information
If both right-side image and left-side image are always displayed, then complete information is available, but display region usage is inefficient
Solution Approach 1:
The display system dynamically adjusts which operation switch images are displayed in which areas based on detected operation inputs. When an operation switch in a specific region is activated, the system responds by displaying images from that region in the corresponding display area. This dynamic adaptation ensures complete information availability when needed while optimizing display region efficiency by showing only relevant information at any given time.
Solution Approach 2:
The system incorporates feedback mechanisms where operation switch detections trigger corresponding display responses. When an operation switch in a particular region is operated, the system receives this feedback and adjusts the display accordingly by showing images from that region in the appropriate area. This feedback-driven approach ensures information availability is maintained while improving display region efficiency through context-responsive content presentation.

AI summary
A vehicular display control device including: memory; and a processor coupled to the memory, wherein the processor is configured to: detect when a right-side operation region provided on a right side of a steering wheel has been operated; detect when a left-side operation region provided on a left side of the steering wheel has been operated; in a case in which operation of the right-side operation region has been detected, display a right-side image corresponding to the right-side operation region in a right-side area of a display region set in front of a driving seat; and in a case in which operation of the left-side operation region has been detected, display a left-side image corresponding to the left-side operation region in a left-side area of the display region.
