Steering Wheel Switch Status Display in the Driver's Forward View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular display systems fail to effectively improve occupant usability by not providing clear visual feedback of the current status of operation region functions, requiring occupants to look away from the road to check switch functions.
Innovation Solution
A vehicular display control device that detects operation of a steering wheel operation region and displays an operation region image and a status image in a display region set in front of the driving seat, allowing occupants to view the current status of switch functions without looking away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only images of operation switches are displayed on the display screen, then the display screen can show the operation region, but the current situation of their corresponding functions remains unknown
Solution Approach 1:
The patent merges the operation region image display and function status information into a single integrated display screen. The display simultaneously shows both the operation region images and their corresponding function status information, eliminating the need for separate displays and providing complete information in one location.
2Loss of information
If the occupant views another display to check function status, then complete information is available, but the occupant must divert gaze from the road
Solution Approach 1:
The patent combines operation region images and function status information on a single display screen positioned in the driver's field of view. This integration allows the driver to obtain complete function status information without needing to shift attention to separate displays, thereby reducing driver distraction while maintaining full information availability.
3Loss of information
If multiple displays are provided to show operation region and status information, then complete information is available, but the display system complexity increases
Solution Approach 1:
The patent consolidates the display of operation region images and function status information onto a single display screen, reducing the number of display components required. This merging approach decreases display system complexity while ensuring that all necessary information is presented in an integrated manner.

AI summary
A vehicular display control device including: a memory; and a processor coupled to the memory, the processor being configured to: detect when an operation region including plural switches provided to a steering wheel has been operated; and in a case in which operation of the operation region has been detected, display, at a display region set in front of a driving seat, an operation region image corresponding to the operation region and a status image indicating a current status of a function allocated to the switch that is being operated among the plural switches.
