Blocked Region Guidance for Faster Autonomous Vehicle Rerouting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous and semi-autonomous vehicles face delays when encountering blocked regions in their environment, leading to prolonged waiting times and potential safety risks for passengers due to the time it takes for remote assistance to provide guidance on navigating around obstacles.
Innovation Solution
A system that allows a computer device to receive sensor data from vehicles and proactively identify blocked regions, transmitting guidance information to the vehicle to plan a new trajectory, enabling quick avoidance of obstacles without explicit requests, using a user interface to annotate and confirm blocked regions for faster assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle waits for remote assistance to provide guidance on navigating around blocked regions, then the vehicle can receive expert help to safely navigate obstacles, but the vehicle experiences prolonged waiting times which delays progress and reduces productivity
Solution Approach 1:
The system proactively identifies blocked regions in the vehicle's path and transmits guidance information before the vehicle encounters them. The remote operator annotates blocked regions on a user interface, and the system automatically sends trajectory adjustment instructions to the vehicle, eliminating the need for the vehicle to wait and request assistance when it reaches the obstacle.
Solution Approach 2:
The system continuously receives sensor data from the vehicle, processes this information through the user interface, and provides real-time feedback by transmitting updated trajectory guidance. This closed-loop feedback mechanism ensures the vehicle receives current information about blocked regions and adjusts its path dynamically without prolonged delays.
2Productivity
If the system proactively identifies and transmits blocked region guidance to vehicles, then the response time is reduced and productivity improves, but the system complexity increases due to additional processing and communication components
Solution Approach 1:
The user interface serves multiple functions: it displays sensor data from the vehicle, allows remote operators to annotate blocked regions, and automatically transmits guidance information to the vehicle. This multi-functional design reduces the need for separate dedicated components for each task, thereby limiting the increase in system complexity while maintaining high productivity.
Solution Approach 2:
The system automatically processes sensor data, identifies blocked regions, and transmits guidance information without requiring manual intervention for each step. The automated workflow reduces the operational complexity on the remote operator side while maintaining high navigation efficiency for the vehicle.
3Measurement precision
If remote operators manually annotate blocked regions on the user interface, then accurate guidance information can be provided, but the process requires more time compared to automated detection
Solution Approach 1:
The system performs preliminary automated detection of blocked regions using sensor data and presents pre-identified regions to the remote operator on the user interface. This preliminary action reduces the time required for manual annotation, as the operator only needs to confirm or adjust pre-processed information rather than analyzing raw sensor data from scratch.
Solution Approach 2:
The user interface acts as an intermediary that presents processed sensor data and suggested blocked regions to the remote operator. This intermediary layer bridges automated detection and manual confirmation, allowing the operator to quickly verify accuracy without performing time-consuming manual analysis, thus maintaining both precision and speed.
Data Source
AI summary
Techniques to provide guidance to a vehicle operating in an environment may include determining a suggested region to block in the environment along a path of the vehicle and causing presentation of the suggested region to block in a user interface of the computer device. Information about the blocked region may be transmitted to one or more vehicles in the environment. Based on the information about the blocked region, at least one of the computer device or a vehicle computer system of the vehicle may control operation of the vehicle to avoid the blocked region.
