In-Vehicle Display Menu Switching for Touch and Steering Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle display systems primarily utilize steering switches for menu selection, but with the increasing use of touch panels, a unified menu system that efficiently operates both touch panels and steering switches has not been effectively implemented, leading to operational complexities.
Innovation Solution
An in-vehicle display system that includes a steering switch, a touch panel, and a central controller, allowing the system to switch between touch panel and steering switch menus, with icons arranged differently in each mode to facilitate easy operation, enabling seamless interaction between touch panel and steering switch inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a unified menu system is implemented to operate both touch panels and steering switches, then ease of operation is improved, but device complexity increases due to the need to manage multiple input methods and menu configurations
Solution Approach 1:
The menu system dynamically changes its icon arrangement based on the detected input method. When a touch panel input is detected, the system displays a first arrangement of icons optimized for touch interaction. When a steering switch input is detected, the system automatically switches to a second arrangement of icons optimized for steering wheel operation. This dynamic adaptation allows the same menu system to serve multiple input methods effectively without requiring separate menu structures, thereby improving ease of operation while managing device complexity.
2Device complexity
If separate menu systems are maintained for touch panels and steering switches, then device complexity is reduced, but ease of operation deteriorates due to operational complexities and lack of unified interface
Solution Approach 1:
The menu system is designed with universal functionality to handle both touch panel and steering switch inputs through a single unified interface. The system detects which input method is being used and automatically adjusts the icon arrangement within the same menu structure. This multi-functional design eliminates the need for completely separate menu systems while maintaining ease of operation for both input methods, as the menu adapts its presentation based on the active input device.
3Ease of operation
If icons are arranged differently for touch panel and steering switch menus, then ease of operation is improved for each specific input method, but device complexity increases due to maintaining multiple icon arrangements
Solution Approach 1:
The system employs dynamic icon arrangement where the same menu structure can automatically reconfigure its icon layout based on the detected input method. When touch panel input is active, icons are arranged in a pattern suitable for finger interaction. When steering switch input is detected, the system automatically rearranges the icons in a different pattern optimized for steering wheel operation. This dynamic reconfiguration allows the system to provide optimized ease of operation for each input method while maintaining a single underlying menu system, thereby managing device complexity.

AI summary
An in-vehicle display system includes a steering switch disposed at a steering wheel, an in-vehicle display having a display screen, and a touch panel covering the display screen. When an operator operates the touch panel, the in-vehicle display is operable to display a touch panel menu including icons on the display screen. When the operator operates the steering switch while the touch panel menu is displayed on the display screen, the in-vehicle display is operable to replace the touch panel menu with a steering switch menu to display the steering switch menu on display screen. The steering switch menu includes the icons arranged differently than the touch panel menu. This in-vehicle display system is suitably used to operate both of the touch panel and the steering switch.
