Vehicle Driving Mode Display with Segmented Responsibility Graphics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face difficulty in intuitively identifying their tasks in various vehicle automation modes, as existing systems lack clear visualization of responsibility distribution between the driver and automated systems.
Innovation Solution
A method and system that generate graphical elements on a display to represent the driver and automated subsystems, with action elements indicating current responsibilities, allowing flexible and intuitive recognition of tasks in different driving modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple automation levels are provided with different control elements, then the vehicle can operate in various driving modes, but the driver cannot clearly identify which tasks he has to perform himself
Solution Approach 1:
The display is segmented into distinct graphical elements: a first graphical element representing the driver, a second graphical element representing the automated subsystem, and action elements representing specific tasks. This segmentation clearly assigns tasks to specific actors, making it intuitive for the driver to understand his responsibilities in each automation mode.
Solution Approach 2:
Different colored markings are used to indicate control responsibility and task assignment. The color coding system provides immediate visual feedback about which actor (driver or subsystem) is responsible for which action, enhancing the driver's ability to quickly comprehend his current tasks without confusion.
2Extent of automation
If control responsibility is distributed between driver and subsystem, then automation can be implemented, but the driver cannot intuitively recognize his tasks
Solution Approach 1:
The system provides continuous visual feedback through the display device, showing the driver which tasks are currently assigned to him and which are handled by the automated subsystem. This feedback mechanism ensures the driver always knows his current responsibilities, making task recognition intuitive despite varying automation levels.
Solution Approach 2:
The display device acts as an intermediary between the automated subsystem and the driver, translating complex control responsibility distributions into simple, intuitive graphical representations. This intermediary clearly communicates task allocation, bridging the gap between automation complexity and driver understanding.

AI summary
The invention relates to a method for displaying driving modes of a vehicle (6). The vehicle (6) can be operated in at least two different driving modes. In the method according to the invention, it is ascertained whether the vehicle (6) is being operated in a first or a second driving mode. In the first driving mode, a first actuator carries out a first action, and in the second driving mode, a second actuator carries out the first action. A first graphical element (7) which represents the first actuator and a second graphical element (8) which represents the second actuator are generated on a display surface (3). Depending on whether the vehicle (6) is in the first or the second driving mode, a first graphical action element (9, 10) which represents the first action is generated with the first (7) and/or second graphical element (8). The invention further relates to a system (1) for displaying driving modes of a vehicle (6).
