Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications systems face challenges in complex and dynamic environments that attenuate or block signals, necessitating improvements in speed, data capacity, efficiency, power usage, reliability, coverage, and device intercommunication, particularly in vehicle-to-everything (V2X) communication systems.

Implementing conditional sensor data sharing methods in V2X communication, where ITS stations share raw sensor data or characteristics based on predefined conditions to optimize bandwidth and resource usage, enhancing object detection accuracy and situational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If raw sensor data is transmitted in V2X messages, then object detection accuracy is improved, but bandwidth consumption increases
Solution Approach 1:
The patent applies local quality by selectively including raw sensor data in V2X messages based on specific conditions. Instead of uniformly transmitting raw data for all objects, the system evaluates each object and determines whether raw sensor data should be included based on factors such as object type, detection confidence, and environmental context. This conditional approach optimizes bandwidth usage while maintaining detection accuracy only when necessary.
2Quantity of substance
If processed object characteristics are transmitted, then bandwidth is preserved, but object detection accuracy decreases
Solution Approach 1:
The patent implements dynamics by making the message content adaptive rather than static. The V2X messages dynamically adjust their composition based on real-time conditions - sometimes containing only processed characteristics, sometimes containing full raw sensor data, and sometimes containing a hybrid. This dynamic adaptation allows the system to optimize the trade-off between bandwidth efficiency and detection accuracy according to current operational needs.
3Loss of energy
If conditional data sharing is implemented, then resource efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining a set of conditions and rules that determine when raw sensor data should be included in V2X messages. These conditions are established in advance based on scenario analysis and expert knowledge, covering various driving situations, object types, and environmental factors. By pre-configuring these decision rules, the system reduces the complexity of real-time decisions while maintaining resource efficiency.
