Vehicle Information Fusion for High-Volume Target Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles face difficulties in transmitting target information acquired by another vehicle due to the increased quantity of targets in its periphery, making it challenging to stabilize various control operations.
Innovation Solution
The vehicle receives vehicle information through vehicle-to-vehicle communication and acquires target information via a server apparatus, allowing stable acquisition and control by combining both types of information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a vehicle directly receives target information from another vehicle through vehicle-to-vehicle communication, then the information acquisition speed is fast, but the system cannot handle high volume of target information effectively
Solution Approach 1:
The patent introduces a server apparatus as an intermediary between vehicles. When target information volume is high, the first vehicle requests target information from the server, which retrieves it from the second vehicle. This mediator approach allows the system to handle large information volumes while maintaining the benefits of vehicle-to-vehicle communication for direct, fast information exchange when volumes are manageable.
2Quantity of substance
If a vehicle acquires target information through a server apparatus, then the information volume handling capability is improved, but the information acquisition time increases due to additional communication steps
Solution Approach 1:
The patent implements a dynamic information acquisition strategy where the system adaptively switches between direct vehicle-to-vehicle communication and server-mediated communication based on the target information volume. When the volume is within acceptable limits, direct communication is used for speed. When the volume exceeds thresholds, the system dynamically transitions to server-mediated acquisition, optimizing the balance between speed and capacity.
3Device complexity
If a vehicle relies solely on vehicle-to-vehicle communication, then the system complexity is low, but the reliability of control operations decreases when target information volume is high
Solution Approach 1:
The patent creates a universal information acquisition system that can operate in multiple modes: direct vehicle-to-vehicle communication for normal conditions and server-mediated communication for high-volume conditions. The server apparatus serves multiple functions including information retrieval, validation, and distribution, enhancing system reliability without requiring complete system redesign.
4Reliability
If the system uses both vehicle-to-vehicle communication and server apparatus, then the reliability and adaptability are improved, but the device complexity increases
Solution Approach 1:
The patent segments the information acquisition function into two distinct pathways: a direct communication pathway for normal operations and a server-mediated pathway for high-volume scenarios. Each pathway is independently optimized, and the system selectively activates the appropriate segment based on conditions, managing complexity through functional segmentation rather than requiring all components to operate simultaneously at full capacity.
Data Source
AI summary
An information processing apparatus mounted on a first vehicle receives vehicle information including information about a travel state of a second vehicle, from the second vehicle by vehicle-to-vehicle communication. Furthermore, when the vehicle information is received from the second vehicle, the information processing apparatus receives, from a server apparatus, target information that is acquired by the second vehicle and that is transmitted by the second vehicle to the server apparatus.
