Solution Overview
Problem
Current techniques for autonomous vehicles to navigate around objects in resource-constrained environments are challenged by the need to process substantial data points, which can lead to inefficiencies in resource utilization and increased latency in trajectory modifications.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current techniques process substantial data points associated with objects, then navigation accuracy is improved, but resource utilization deteriorates and latency increases
Solution Approach 1:
The patent extracts only the essential data elements needed for navigation decisions from the substantial data points. By projecting objects onto a 2D plane and identifying only critical features (position, size, velocity), the system discards redundant information while maintaining navigation accuracy, thus improving resource utilization.
Solution Approach 2:
The patent segments the complex navigation problem into distinct components: object detection, projection onto lateral motion boundary, classification, and trajectory modification. This segmentation allows each component to process only necessary data, reducing overall computational load while maintaining accuracy.
2Measurement precision
If current techniques process substantial data points associated with objects, then navigation accuracy is improved, but latency in trajectory modifications increases
Solution Approach 1:
The patent extracts only critical object features (position, size, velocity) needed for immediate navigation decisions, discarding redundant data. This extraction enables rapid processing with minimal latency while maintaining the accuracy needed for safe navigation.
Solution Approach 2:
The patent performs preliminary projection of objects onto the lateral motion boundary before full trajectory calculation. This preliminary action pre-processes data into a format ready for quick decision-making, reducing the time needed for final trajectory modifications.
3Use of energy by moving object
If a lateral motion boundary system projects objects onto vehicle trajectory, then processing power usage is reduced, but navigation complexity increases
Solution Approach 1:
The patent transforms the 3D navigation problem into a 2D problem by projecting objects onto the lateral motion boundary. This dimensionality reduction simplifies calculations significantly, reducing processing power requirements while the systematic approach to projection and classification manages the apparent complexity.
Solution Approach 2:
The lateral motion boundary serves multiple functions simultaneously: it defines vehicle limits, projects objects for classification, and guides trajectory adjustments. This multi-functionality reduces overall system complexity by consolidating multiple navigation tasks into a single unified framework.

AI summary
Techniques for determining a modified lateral motion boundary of a vehicle in an environment are discussed herein. Techniques may include determining a lateral motion boundary for a vehicle in an environment, based partly on data associated with the environment and/or the vehicle, where representations of objects in the environment may be projected onto the lateral motion boundary. The lateral motion boundary may be modified based on such projections to determine a modified lateral motion boundary. The modified lateral motion boundary may include an open lateral boundary, configured by closing off portions of the lateral motion boundary corresponding to the projections, allowing a vehicle to move laterally to traverse the environment and avoid the objects.
