Vehicle-to-X Redundant Information Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-X communication systems do not effectively address the issue of redundant information processing, leading to unnecessary computational load and potential overtaxing of vehicle systems, as they focus solely on data integrity checks and do not consider redundant information items received through multiple messages.
Innovation Solution
A method that identifies and processes redundantly received information items by entering them into an information table for matching, allowing only unique items to be processed, thereby reducing computational load and preventing overtaxing of driver assistance systems, and utilizing multiple communication paths to validate and manage information items based on their redundancy and resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle-to-X messages are transmitted through multiple communication paths and multihop methods to increase transmission range and reliability, then the coverage and reliability of the communication system are improved, but redundant information items are received repeatedly causing unnecessary computational load and potential overtaxing of vehicle systems
Solution Approach 1:
The patent applies preliminary action by creating an information table before processing information items, where received information items are first entered into the table and checked for redundancy against previously received items. This preliminary redundancy check prevents duplicate processing before the computational load occurs, allowing the system to maintain high transmission reliability through multihop methods while avoiding unnecessary processing of redundant information.
2Loss of information
If all received information items are processed without redundancy checking to ensure complete data processing, then data completeness is maintained, but computational resources are wasted on redundant information items
Solution Approach 1:
The patent uses copying by creating a record copy of each information item in the information table before processing. When a new information item is received, it is first copied into the table and compared against existing records to identify redundancy. This allows the system to maintain complete data tracking while avoiding duplicate processing of identical information items, thus preserving data completeness while reducing computational energy consumption.
3Reliability
If redundancy checking is implemented by comparing all received information items against all previously received items, then redundant information is accurately identified, but the complexity of the processing system increases
Solution Approach 1:
The patent applies segmentation by dividing the redundancy checking process into distinct functional modules: an information table for storage, an entry module for receiving information items, and a checking module for comparing items. This segmentation allows the system to accurately identify redundant information through systematic comparison while managing complexity through modular design, where each module has a specific function rather than a monolithic complex processing system.

AI summary
A method for identifying redundantly received information in which the information is contained in vehicle-to-X messages, one vehicle-to-X message comprising at least one item of information, a plurality of vehicle-to-X messages being received by a receiver, and at least one portion of a total number of items of information being received redundantly. The received items of information are entered into an information table and matched with one another before the received information is processed.
