METHOD AND SYSTEM FOR DETECTING MESSAGE LATENCY AND FAULTS WITHIN A COMPUTING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18063455 titled 'METHOD AND SYSTEM FOR DETECTING MESSAGE LATENCY AND FAULTS WITHIN A COMPUTING SYSTEM
Simplified Explanation: This patent application describes a system for detecting faults or latency in a computing system, specifically in the context of an autonomous vehicle. The system tracks messages sent between different subsystems of the vehicle to identify delays or issues in communication.
- Messages are sent from publishers to subscribers within the vehicle's communication system.
- Checkpoints along the communication path record message IDs and timestamps to measure latency.
- If the measured latency exceeds a threshold, the vehicle can take corrective action.
Key Features and Innovation:
- Monitoring communication between subsystems in an autonomous vehicle.
- Tracking message IDs and timestamps to measure latency.
- Implementing remedial actions based on detected faults or delays.
Potential Applications: This technology can be applied in various autonomous vehicles to ensure efficient and reliable communication between subsystems.
Problems Solved:
- Detecting faults or latency in a computing system.
- Improving communication reliability in autonomous vehicles.
Benefits:
- Enhances the overall performance and safety of autonomous vehicles.
- Enables proactive maintenance and troubleshooting of communication issues.
Commercial Applications: The technology can be utilized in the automotive industry for autonomous vehicles, enhancing their communication systems and ensuring optimal performance.
Prior Art: Readers can explore prior research on fault detection and latency monitoring in autonomous vehicles and computing systems.
Frequently Updated Research: Stay updated on advancements in fault detection systems for autonomous vehicles and computing technologies.
Questions about Fault Detection in Autonomous Vehicles: 1. How does this technology contribute to the safety of autonomous vehicles? 2. What are the potential implications of implementing this system in other industries?
Original Abstract Submitted
This document discloses system, method, and computer program product embodiments for detecting a fault or latency in a computing system, such as that of an autonomous vehicle. In the computing system, messages are received from subsystems of the vehicle that are publishers and transferred along a communication path to subsystems of the vehicle that are subscribers. The method includes receiving, from checkpoints along the communication path, for each of a group of messages that are transmitted along the communication path, a message ID and a timestamp indicating when the checkpoint receives the message, publishes the message, or publishes a result derived from the message. The method also includes using the message IDs and the timestamps to measure an amount of latency that occurred in the communication path before that message reached its corresponding subscriber. When the measured latency does not satisfy a threshold, the vehicle may take a remedial action.
