Vehicle-to-X Channel Load Detection for Adaptive Message Preprocessing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-X communication systems face challenges in efficiently managing channel load, particularly during the transition from low to high computing power requirements, where preprocessing becomes necessary to maintain system performance, and existing methods lack precision in determining channel load and adapting preprocessing accordingly.
Innovation Solution
A method for determining channel load in vehicle-to-X communication that involves calculating multiple parameters, including message count, timestamp intervals, buffer memory occupancy, and message types, to assess computing power needs, allowing for dynamic adjustment of preprocessing based on these parameters.

1Productivity
If preprocessing is performed to reduce system load, then processing efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by performing preprocessing operations before full message processing. The system pre-filters incoming vehicle-to-X messages based on relevance criteria (such as message type, source reliability, and spatial-temporal context) before committing computational resources to complete processing. This early filtering reduces the burden on the main processing system while maintaining the ability to handle high message volumes efficiently.
2Measurement precision
If multiple channel load parameters are determined to assess computing power needs, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing channel load assessment into multiple independent parameters rather than using a single complex metric. Specifically, it segments the assessment into: (1) message reception rate, (2) message processing time, (3) buffer occupancy level, and (4) computing resource utilization. Each parameter is measured and evaluated separately, then combined to form a comprehensive channel load assessment. This segmented approach improves measurement precision while keeping individual measurement operations simple and manageable.
