Autonomous Vehicle Path Verification HMI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack effective human-machine interfaces to display and verify vehicle paths, making it difficult for occupants to verify and alter autonomous vehicle operations, especially when objects are detected in the path, and there is a need for better decision-making and collision avoidance mechanisms.
Innovation Solution
A vehicle system that includes a computing device with sensors and a human-machine interface (HMI) to provide occupants with information about detected objects and allow input on path alterations, using a graphical user interface to display potential paths and alert options for collision avoidance, with the ability to accept or reject proposed evasive maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous vehicle computing device makes all decisions concerning vehicle operations, then automation level is improved, but human ability to verify and alter operations is reduced
Solution Approach 1:
The system provides feedback to the human operator by displaying the planned path and detected objects through the HMI, allowing the operator to verify the autonomous vehicle's decisions and provide input for alterations, thus maintaining automation while enabling human oversight
Solution Approach 2:
The HMI acts as an intermediary between the autonomous computing device and the human operator, translating machine decisions into visual representations that humans can understand and verify, and conveying human input back to the system
2Loss of information
If HMI displays detailed path information and object detections, then information completeness is improved, but interface complexity is increased
Solution Approach 1:
The HMI displays information in segmented, distinct visual elements showing the planned path and detected objects separately, allowing comprehensive information presentation while maintaining interface clarity through organized segmentation of data
Data Source
AI summary
A vehicle is operated at least partially autonomously. A predicted path of the vehicle is monitored to identify an object with which the vehicle is likely to collide. A graphical user interface (GUI) is provided that includes the predicted path, a proposed path for the vehicle to avoid a collision with an object, and the vehicle. A selection is made to follow one of the predicted path and the proposed path. The GUI is updated to include the selected one of the predicted path and the proposed path, along with a location of the vehicle on the selected one of the predicted path and the proposed path.
