AV Perception Adjustment for Obstacle Footprint Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles (AVs) face challenges in navigating through environments with obstacles, as existing systems require human Remote Advisors to either ignore objects, which poses safety risks, or manually steer the AV, which is limited by bandwidth and contextual constraints.
Innovation Solution
The system provides additional options for the Remote Advisor to modify the perception of objects by adjusting the object's footprint or the AV's footprint, allowing the AV to autonomously navigate past obstacles while maintaining safety protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the Remote Advisor ignores the detected object, then the AV can proceed without manual intervention, but safety risks increase due to potential collisions
Solution Approach 1:
The patent introduces an intermediary system (the perception adjustment interface and footprint modification mechanism) between the Remote Advisor and the AV navigation system. This intermediary allows the Remote Advisor to subtly modify object footprints or AV footprints to guide the AV around obstacles without completely ignoring safety protocols, thus balancing productivity and reliability
2Reliability
If the Remote Advisor manually steers the AV, then safety is maintained through direct control, but bandwidth limitations and contextual constraints reduce efficiency
Solution Approach 1:
The patent enables the AV to serve itself by making autonomous navigation decisions based on modified perception data. The Remote Advisor only needs to provide high-level guidance through footprint adjustments rather than continuous manual steering, allowing the AV's autonomous systems to handle the actual navigation while maintaining safety through the Advisor's oversight
Solution Approach 2:
The system dynamically adjusts the level of human intervention based on the situation. The Remote Advisor can choose between subtle footprint modifications for routine obstacles and more direct intervention for complex scenarios, creating a flexible control system that optimizes both safety and efficiency
3Reliability
If the object footprint is enlarged to ensure safety, then collision risk is reduced, but the AV's ability to navigate through tight spaces decreases
Solution Approach 1:
The patent allows the Remote Advisor to apply different footprint adjustments to different parts of the navigation problem. Instead of uniformly enlarging all object footprints, the system can selectively modify specific footprint regions or apply different adjustment levels to different objects, preserving navigation flexibility while maintaining collision avoidance where needed

AI summary
Aspects of the disclosed technology provide systems and methods that allow adjustment of a perception of an object by an autonomous vehicle (AV). The system includes a remote assistance platform (RAP) communicatively coupled to the AV. The RAP has a user interface that enables a human Remote Advisor to view an environment around the AV through a sensor system of the AV and issue instructions to the AV. The RAP is configured to allow the Remote Advisor to select an adjustment of the perception of the object by the AV and instruct the AV to implement the selected adjustment and then navigate autonomously.
