Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The driving assistance communication system faces a high load in verification processing due to the need to receive and verify vehicle information from multiple sources simultaneously, which increases processing demands on communication devices.
Innovation Solution
A communication device with a receiver, verifier, and mapping generator is implemented to receive and verify synthesis messages containing information about multiple vehicles, allowing for the generation of mapping information that represents relative positions, reducing the load on verification processing by prioritizing verification of synthesis information over individual vehicle messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the communication device receives and verifies vehicle information from multiple vehicles simultaneously, then the system can acquire comprehensive information about surrounding vehicles, but the verification processing load increases significantly
Solution Approach 1:
The patent combines verification of multiple vehicle information messages into a single verification operation by synthesizing information from multiple vehicles and performing one verification on the synthesized data, rather than verifying each message separately
Solution Approach 2:
The verification mechanism is designed to handle multiple vehicle information sources universally through a single verification process that can process synthesized information from any number of vehicles, making the verification system multi-functional
2Reliability
If the communication device performs verification processing on each received message, then information authenticity is ensured, but processing time and computational resources increase
Solution Approach 1:
Multiple verification operations are merged into a single verification process by synthesizing vehicle information from multiple sources first, then performing one verification on the synthesized information, reducing total processing time while maintaining authenticity checks
3Productivity
If the communication device receives information from many vehicles at high frequency, then the system provides comprehensive real-time awareness, but the processing capability requirement increases
Solution Approach 1:
The patent merges multiple high-frequency information streams into synthesized information that can be processed in fewer verification operations, reducing the processing capability requirements while maintaining comprehensive real-time awareness
Solution Approach 2:
The system performs preliminary synthesis of vehicle information from multiple sources before verification, organizing the data in advance to reduce the complexity of subsequent verification processing operations

AI summary
According to an embodiment, a communication device is installed in a movable body and includes a receiver, a verifier, and a mapping generator. The receiver is configured to receive a synthesis message including synthesis information and second verification information. The synthesis information is information about motion of a plurality of movable bodies including the movable body installed with the device; the second verification information is information indicative of a validity of the synthesis information. The verifier is configured to verify the validity of the synthesis information on the basis of the second verification information. The mapping generator is configured to generate mapping information on the basis of the synthesis information verified as valid. The mapping information represents a relative position of at least one of the movable bodies with respect to the movable body installed with the device.
