V2X Event Fusion for Driving Decision Information Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-everything (V2X) systems face challenges in processing vast amounts of information without considering user decision-making abilities, correlating events, and personalizing information display.
Innovation Solution
A method and apparatus that merge driving decision-making homogeneous events to generate composite events, applying preset influence relationships, and display them using voice, text, or icons, while filtering and broadcasting to enhance user decision-making efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple pieces of event information are obtained through V2X communication, then the quantity of information increases, but the information processing efficiency deteriorates due to lack of correlation and prioritization
Solution Approach 1:
The patent merges multiple homogeneous events into a single composite event when they share the same event type and occur within a predefined time window. This consolidation reduces the total number of events that require processing, thereby improving information processing efficiency while maintaining the quantity of relevant information through the composite event structure that preserves individual event details.
Solution Approach 2:
The patent segments event processing into distinct phases: event reception, homogeneity judgment, composite event generation, and differential processing. By dividing the processing workflow into manageable segments with clear decision points, the system efficiently handles large quantities of events without overwhelming processing resources.
2Loss of information
If all event information is processed individually, then complete information coverage is achieved, but the decision-making burden on drivers increases
Solution Approach 1:
Homogeneous events are merged into composite events that preserve all individual event information while presenting a unified structure to the driver. The composite event contains references to all constituent events, ensuring complete information coverage is maintained while reducing the number of separate alerts the driver must process.
Solution Approach 2:
The patent applies different processing qualities to different event types: homogeneous events are merged into composite events with consolidated presentation, while heterogeneous events are processed individually. This localized quality adjustment ensures that information coverage is maintained for all events while reducing decision-making burden specifically for redundant homogeneous events.
3Speed
If event processing is performed without considering influence relationships, then processing speed is maintained, but the relevance of information to driving decisions decreases
Solution Approach 1:
The patent performs preliminary judgment of event homogeneity and influence relationships during the event reception phase, before full processing begins. By pre-identifying homogeneous events and their relationships, the system maintains processing speed while ensuring that relevant information is properly correlated and prioritized in the subsequent composite event generation stage.

AI summary
The present disclosure provides a cooperative vehicle infrastructure information processing method and apparatus, and a terminal device. The method includes: receiving a plurality of pieces of event information sent by an information sensor device; and in a case that at least two target events among the plurality of pieces of event information are driving decision-making homogeneous events, merging the at least two target events to generate a composite event, wherein the driving decision-making homogeneous events are events having a preset influence relationship.
