Remote Vehicle Guidance for Complex Maneuver Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in navigating complex or unexpected situations, such as construction zones, where they need to decide whether to move onto oncoming traffic lanes, requiring sophisticated verification processes that current systems may not adequately handle.
Innovation Solution
A remote guidance system for autonomous vehicles that includes sensors to detect trigger events, a transceiver to communicate with a server, and a controller to receive and verify driving instructions, allowing the vehicle to autonomously perform maneuvers based on prioritized trajectories provided by the server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous vehicle controller processes complex sensor data independently, then the vehicle can maintain operational autonomy, but the system may fail to handle sophisticated verification requirements for complex maneuvers
Solution Approach 1:
The patent introduces a remote server as an intermediary between the autonomous vehicle controller and the complex verification requirements. The server receives sensor data from the vehicle, performs sophisticated verification for complex maneuvers (such as construction zone navigation), and returns verification results to the controller. This mediator approach enables the vehicle to handle complex situations that exceed the controller's independent processing capabilities while maintaining operational autonomy.
2Reliability
If the vehicle sends all sensor data to a remote server for verification, then sophisticated maneuvers can be verified, but communication latency may increase
Solution Approach 1:
The patent implements partial action by selectively transmitting only the necessary sensor data and maneuver verification requests to the remote server, rather than sending all sensor data continuously. The controller determines when verification is needed based on the complexity of the maneuver and sends targeted queries to the server. This approach achieves sophisticated verification while minimizing communication time and data transmission overhead.
3Reliability
If the controller implements comprehensive verification protocols for all maneuvers, then safety is improved, but the system complexity and processing load increase
Solution Approach 1:
The patent segments the verification system into two distinct parts: a local controller that handles routine maneuver verification and a remote server that handles complex maneuver verification. The controller includes a maneuver verification module for local checks and a server communication module for remote verification. This segmentation allows comprehensive safety verification to be achieved while distributing system complexity between the vehicle's onboard systems and the remote infrastructure.

AI summary
A vehicle includes a sensor configured to provide sensor data indicative of an environment outside the vehicle; a transceiver configured to communicate with a server; and a controller configured to, responsive to the sensor data indicative of a predefined trigger event, send a request for remote guidance to the server, receive an instruction from the server indicative of a first trajectory having a first priority and a second trajectory having a second priority, and perform a driving maneuver to implement one of the first trajectory or the second trajectory.
