V2X Communication Range Determination Using Sensor Object Properties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication systems determine communication ranges based solely on reaction time, which may not account for dynamic factors such as object properties and environmental conditions, potentially leading to inefficiencies in data transmission and safety in dynamic traffic scenarios.
Innovation Solution
V2X devices utilize sensor information to dynamically determine communication ranges for V2X messages based on detected object properties, such as location, speed, and direction, and transmit this information within the message to ensure relevant data reaches nearby vehicles, enhancing safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If communication range is determined solely by reaction time, then the determination process is simple, but the accuracy and adaptability to dynamic traffic scenarios deteriorates
Solution Approach 1:
The patent makes the communication range determination dynamic by continuously monitoring object properties (speed, direction, distance) and adjusting the communication range accordingly. Instead of using a fixed reaction-time-based range, the system adapts the communication range in real-time based on the detected object's characteristics and environmental conditions, resolving the contradiction between simple determination and accurate adaptation.
Solution Approach 2:
The system changes multiple parameters simultaneously - using object speed, direction, distance, and environmental factors to dynamically adjust the communication range parameter. This multi-parameter approach allows the system to achieve high accuracy in determining appropriate communication ranges while maintaining a systematic determination process that doesn't overly complicate the overall architecture.
2Reliability
If communication range is expanded to cover more dynamic factors, then the safety and reliability improve, but the data transmission efficiency may deteriorate due to increased message size
Solution Approach 1:
The patent extracts and transmits only the essential object properties (speed, direction, distance, type) that are necessary for determining communication range, rather than transmitting all available sensor data. This selective extraction maintains safety and reliability by including critical dynamic factors while preserving data transmission efficiency by minimizing message size to only the most relevant parameters.
Solution Approach 2:
The system applies partial action by including only the necessary subset of object properties in V2X messages rather than all possible dynamic factors. This approach achieves sufficient safety and reliability for dynamic scenario handling without the overhead of transmitting excessive data, thus maintaining good transmission efficiency while improving upon the traditional reaction-time-only approach.
3Adaptability or versatility
If sensor information is integrated into V2X messages, then the adaptability to different traffic scenarios improves, but the device complexity increases
Solution Approach 1:
The patent implements a universal sensor integration approach where a single sensor system captures multiple object properties (speed, direction, distance, type) that can be applied across various traffic scenarios. This multi-functional sensor framework provides adaptability to different scenarios without requiring separate specialized systems for each scenario, thus improving versatility while controlling device complexity through unified sensor and processing architecture.
