Mobile Device Visual Information Display for Automated Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with at least partially automated driving, there is a need to enhance the usability of mobile devices and effectively communicate visual information to occupants about the traffic situation and required actions, ensuring they can quickly focus on driving when necessary.
Innovation Solution
A method and device that utilize a mobile user device to output visual information, such as image sequences, representing the detected traffic situation and required actions, with parameters like degree of automation and limiting values, facilitating rapid understanding and attention redirection to the vehicle surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual information is continuously displayed on the mobile device during automated driving, then the occupant can stay informed about the traffic situation, but the occupant may become distracted and fail to notice when driver attention is required
Solution Approach 1:
The display content and characteristics are dynamically adjusted based on the automated driving system's state. When the system requires driver attention, the display automatically changes to alert the occupant. When automated driving is stable, normal visual information can be displayed. This dynamic adaptation resolves the contradiction by making the display behavior contingent on system needs rather than static.
Solution Approach 2:
The system implements feedback loops where the automated driving system communicates its attention requirements to the mobile device display. The display receives feedback about system state and adjusts its behavior accordingly. This feedback mechanism ensures that information display does not compromise safety by prioritizing driver attention when needed.
2Loss of information
If the mobile device provides detailed visual information about traffic situations, then the occupant can understand the environment better, but the information may be too complex to process quickly when driver intervention is needed
Solution Approach 1:
Visual information is segmented into hierarchical levels of detail and priority. Critical safety-related information is separated from general contextual information. When driver attention is required, only the most essential segmented information is displayed prominently, allowing rapid comprehension without cognitive overload from unnecessary details.
Solution Approach 2:
Different regions or aspects of the displayed information have different qualities and priorities. Critical information elements are highlighted with enhanced visual properties (brightness, size, position) while less critical information is dimmed or minimized. This local quality differentiation enables selective attention to essential elements during time-critical situations.
Data Source
AI summary
A method produces visual information, by way of a mobile user device, for at least one occupant of the vehicle in connection with at least partially automated driving, in which method visual information, in particular an image sequence, is displayed on a display of the mobile user device. The image sequence represents a traffic situation detected by the vehicle and/or a need for action of an occupant which is requested or recommended in this context.
