Vehicle HMI Display Modes for Low-Distraction Information Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle human machine interfaces (HMIs) cause visual, cognitive, and manual distractions during vehicle operation due to information overload and complex navigation through menus to change display modes.
Innovation Solution
A system and method for a vehicle HMI that includes an input device positioned proximate to the rider's thumb, allowing easy control of display modes without removing the hand from the handlebar, and enabling switching between display modes with a single action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If HMIs display more information to provide comprehensive vehicle data, then information completeness is improved, but users experience information overload and increased distractions
Solution Approach 1:
The HMI display is segmented into multiple pages, each dedicated to specific vehicle functions or information categories. Users can navigate between pages to access different sets of information, allowing comprehensive data presentation without overwhelming the user with all information simultaneously on a single display.
Solution Approach 2:
The HMI system dynamically adjusts the displayed information based on vehicle operating conditions, user preferences, and context. The display content changes adaptively to show only relevant information at given moments, reducing information overload while maintaining completeness of available data.
2Adaptability or versatility
If HMIs provide comprehensive access controls and menus to customize display options, then user customization capability is improved, but interaction complexity and cognitive load increase
Solution Approach 1:
The system provides preset display configurations that are pre-configured for common user needs. Users can quickly switch between these pre-defined modes without navigating complex menus, while still having the option to customize individual parameters when desired.
Solution Approach 2:
Instead of requiring users to navigate through complex menus to access display options, the system inverts the approach by placing essential controls directly on the display interface or within easy reach of the rider, allowing direct manipulation of display settings without hierarchical menu navigation.
3Ease of operation
If input controls are positioned for easy access near the rider's hand, then ease of operation is improved, but control precision and accuracy may be reduced
Solution Approach 1:
The input device positioned near the rider's hand is designed with multi-functionality, allowing it to perform various control operations including display mode switching, menu navigation, and parameter adjustment. This universal design maintains precision by incorporating distinct tactile feedback mechanisms for different functions while remaining easily accessible.

AI summary
Systems and methods for displaying information regarding a vehicle on a display device of a vehicle. One system includes a display device, an input device, and an electronic controller including an electronic processor and memory. The electronic controller is configured, during operation of the vehicle, to display, on the display device, information regarding the vehicle in a first display mode of a plurality of available display modes, the first display mode including a first set of information, and, in response to receiving input via the input device while the information is displayed in the first display mode, switch to displaying information regarding the vehicle in a second display mode of the plurality of available display modes. The second display mode includes the first set of information and a second set of information, and the second set of information is configurable.
