Autonomous Vehicle Disengagement Alerts for Networked Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack effective mechanisms for alerting other vehicles and network components to instances of autonomous driving disengagement, which can impact the safety and efficiency of autonomous vehicle operations.
Innovation Solution
The system identifies instances of autonomous driving disengagement and transmits over-the-air messages to alert other vehicles and network components, providing an indication of the disengagement and optional information such as disengagement cause and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving vehicles operate without disengagement alerting mechanisms, then the system complexity remains low, but safety and efficiency of autonomous vehicle operations deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where autonomous vehicles transmit disengagement status information to the network and receive alert messages in response. This closed-loop feedback system allows the network to monitor vehicle disengagement states and provide appropriate alerts, improving safety while maintaining manageable system complexity through standardized communication protocols
Solution Approach 2:
The network serves as an intermediary between autonomous vehicles, receiving disengagement status information from vehicles and generating alert messages that are transmitted back to vehicles or other network components. This intermediary role centralizes the complexity of alert generation and distribution, simplifying individual vehicle systems while enhancing overall safety
2Loss of information
If disengagement alert messages are transmitted to all network components, then information availability improves, but network communication overhead increases
Solution Approach 1:
The patent applies local quality by transmitting disengagement alert information selectively to specific network components based on their relevance and proximity to the disengaged vehicle. Rather than universal broadcasting, the system directs alerts to nearby vehicles and pertinent network entities, reducing unnecessary communication overhead while ensuring information reaches those who need it most
Solution Approach 2:
The network communication system is segmented into targeted communication channels that route disengagement alerts to specific recipient groups (nearby vehicles, network management systems, etc.). This segmentation allows efficient distribution of information without requiring all network components to process every alert message, thereby reducing overall communication overhead

AI summary
This disclosure provides systems, methods, and devices for wireless communication that support vehicle alerting, such as in autonomous driving networks. Vehicle alerting may provide messages alerting other vehicles and/or network components to instances of autonomous driving disengagement. A vehicle operating according to an autonomous vehicle (AV) mode may transmit an over-the-air message to one or more other devices, such as nodes of an autonomous driving network, to alert the one or more devices to the vehicle disengaging the AV mode. A device receiving an autonomous disengagement message may alter one or more autonomous operation aspects in response to the over-the-air message. Other aspects and features are also claimed and described.
