Autonomous Vehicle Situation Awareness Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack systems to effectively present situation awareness information to occupants, which could enhance comfort and safety by alerting and informing them about environmental elements and potential threats, without overwhelming them with data.
Innovation Solution
A situation awareness information system that processes environmental data into layers, extracts this data into a point cloud, and projects it onto a meta-template with manipulable features to generate display data, providing an integrated and holistic interface to occupants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If situation awareness information is presented to occupants in an autonomous vehicle, then occupant comfort and safety awareness are improved, but information overload and cognitive burden increase
Solution Approach 1:
The system segments situation awareness information into multiple hierarchical layers (raw sensor data, processed environmental elements, significant events, and contextual interpretations). This layered segmentation allows occupants to access detailed information only when needed while receiving filtered summaries by default, thereby improving situation awareness without overwhelming cognitive processing capacity.
Solution Approach 2:
The patent introduces an intelligent intermediary system that acts as a mediator between autonomous vehicle sensors and human occupants. This intermediary processes, filters, and translates raw sensor data into meaningful situation awareness information, selecting and prioritizing only the most relevant data for presentation to occupants, thus reducing information overload while maintaining reliability.
2Reliability
If comprehensive environmental data is provided to occupants, then safety awareness is improved, but data processing complexity and time increase
Solution Approach 1:
The system performs preliminary processing and filtering of environmental data in advance, organizing sensor inputs into pre-categorized layers of significance before presentation to occupants. By pre-processing data into hierarchical layers during normal operation, the system enables rapid access to safety-critical information when needed without requiring real-time complex processing during critical moments.
Solution Approach 2:
The patent applies local quality by providing different levels of data processing and detail to different types of information based on their safety criticality. Safety-critical information receives immediate, simplified processing and prominent presentation, while less critical environmental data undergoes more comprehensive but lower-priority processing, optimizing both safety awareness and processing efficiency.
3Loss of information
If detailed situation awareness information is displayed, then occupant understanding of environmental elements is improved, but interface complexity and ease of operation deteriorate
Solution Approach 1:
The display interface dynamically adapts its complexity and level of detail based on the operational context, vehicle automation level, and detected occupant needs. The system can transition between simplified summaries and detailed environmental data presentations, adjusting the interface in real-time to maintain ease of operation while ensuring comprehensive environmental understanding when required.
Solution Approach 2:
The patent adds a temporal and hierarchical dimension to information presentation by organizing detailed situation awareness data into structured layers that can be accessed at different depths. Occupants can view high-level summaries or drill down into specific environmental elements and sensor data sources, transforming a potentially overwhelming two-dimensional display into a multi-layered interactive interface that maintains usability while providing comprehensive information.
