Vehicle Sensor Data Filtering for Occlusion-Aware V2X Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sensors face challenges with occlusion and limited range, necessitating improved methods for sensor data sharing among vehicles and infrastructure to enhance environmental awareness.
Innovation Solution
A method for vehicle-to-vehicle and vehicle-to-everything communication using sensor data filtering conditions to request and transmit relevant sensor data, specifically identifying and requesting data from occluded regions within the field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor data is shared from all neighboring devices to compensate for occlusion and range limitations, then environmental awareness is improved, but over-the-air congestion and processing overhead increase
Solution Approach 1:
The patent applies local quality by transmitting sensor data selectively based on spatial relevance. Each vehicle requests sensor data only from specific regions (occluded regions or regions beyond sensor range) rather than receiving all sensor data from neighboring devices. This targeted approach maintains environmental awareness while reducing unnecessary data transmission and air interface congestion.
Solution Approach 2:
The patent extracts only the necessary sensor data from neighboring devices by defining specific filtering conditions. Instead of sharing complete sensor datasets, the system extracts and transmits only the portions of sensor data that correspond to occluded regions or regions beyond the requesting vehicle's sensor range, thereby reducing processing overhead and communication load.
2Object-generated harmful factors
If sensor data filtering conditions are implemented to reduce data transmission, then over-the-air congestion is reduced, but measurement precision of sensor data requirements may be compromised
Solution Approach 1:
The patent implements dynamic filtering conditions that adapt to the specific occlusion and range limitations of each vehicle. The filtering criteria are not static but are determined in real-time based on the requesting vehicle's sensor capabilities, occluded regions, and the spatial relationship with neighboring devices. This dynamic approach ensures accurate filtering while maintaining the precision needed for safety-critical applications.

AI summary
In an aspect, a vehicle apparatus monitors, via a set of sensors communicatively coupled to the vehicle apparatus, a field of view (FOV) of the vehicle apparatus. The vehicle apparatus transmits, based on the monitoring, a first message that requests sensor data from one or more neighboring devices and indicates at least one sensor data filtering condition for the requested sensor data. A communication device receives the first message, and determines whether sensor data is available at the communication device which satisfies the at least one sensor data filtering condition for the requested sensor data. If so, the communication device filters its sensor data based on the at least one sensor data filtering condition, and transmits, to the vehicle apparatus, a second message including the filtered sensor data.
