Vehicle Message Relevance and Validity Filtering for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current advanced driver assistance systems (ADAS) operate independently of nearby vehicles, leading to redundant operations, wasted resources, and potential vehicle collisions due to unvalidated and unverified messages, especially in V2V communication systems.
Innovation Solution
A system and method for determining relevance and validity of communication messages between vehicles by using environment information and relevance criteria, including device characteristics, location, and signal characteristics to validate and prioritize messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all received messages are processed without filtering, then message completeness is maintained, but processing resources are wasted on irrelevant messages
Solution Approach 1:
The system performs preliminary actions by determining relevance and validity of messages before processing them. The receiving device evaluates message characteristics and sender information in advance to filter out irrelevant messages, preventing wasted processing resources on messages that would not affect the receiving device's operations.
Solution Approach 2:
The system applies local quality by tailoring message processing based on the specific characteristics of each message and its sender. Different messages are treated differently based on their relevance to the receiving device's location, function, and current operations, optimizing processing efficiency for each individual message.
2Speed
If message validation is skipped to improve processing speed, then response time is reduced, but system security and reliability deteriorate
Solution Approach 1:
The system performs validation actions preliminarily before processing messages. The receiving device determines the validity of messages by checking sender credentials and message characteristics in advance, ensuring secure and reliable message processing while maintaining efficient throughput by filtering out invalid messages early.
3Adaptability or versatility
If redundant operations are performed by all vehicles, then operational independence is maintained, but system efficiency and resource utilization worsen
Solution Approach 1:
The system merges operations by enabling vehicles to coordinate their functions through validated messages. Instead of each vehicle performing all operations independently, vehicles can share operational information and coordinate actions, reducing redundant computational resources while maintaining operational independence through selective cooperation.
Solution Approach 2:
Vehicles perform preliminary validation of message relevance before executing operations. This preliminary filtering allows vehicles to maintain operational independence by selectively processing only relevant messages while avoiding redundant operations on irrelevant information, thereby reducing overall computational resource consumption.
4Productivity
If unvalidated messages are processed, then processing throughput is maintained, but safety and collision avoidance capability deteriorate
Solution Approach 1:
The system performs validation actions preliminarily before processing messages for safety-critical functions. The receiving device determines the validity of messages by verifying sender credentials and message characteristics in advance, ensuring that only trusted messages are processed for collision avoidance and safety functions, thereby preventing spoofed messages from causing harmful effects.

AI summary
Disclosed is a method and apparatus for operating a first device. The first device obtains environment information in proximity to the first device and receives one or more communication messages from a second device and the message(s) includes relevance criteria, wherein the relevance criteria indicates one or more devices, one or more sets of device characteristics, one or more lanes, one or more intersections or areas, one or more pedestrian paths or bicycle paths, one or more signal characteristics from the second device or any combination thereof. The first device determines whether the one or more communication messages are relevant to the first device based on the relevance criteria and the environment information and performs an operation in response to the determination of whether the one or more communication messages are relevant.
