Roadside Communication Device Dynamic Range Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In road-to-vehicle communication, existing systems fail to adapt the transmission range of roadside communication devices based on the attributes of received information, traffic properties, and environmental conditions, leading to ineffective transfer of information to the most appropriate vehicle.
Innovation Solution
A roadside communication device equipped with a reception unit, a determination unit that adjusts the notification target range based on information attributes, traffic properties, and environmental states, and a transmission unit that sends signals to wireless terminals within the determined range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the roadside communication device uses a fixed transmission range, then the device complexity is reduced, but the information cannot be transferred to the appropriate vehicle according to information attributes, traffic properties, and environmental conditions
Solution Approach 1:
The patent applies dynamics by making the notification target range adjustable rather than fixed. The determination unit dynamically changes the notification target range based on information attributes (such as importance degree), traffic properties (such as vehicle speed), and environmental state (such as weather conditions), allowing the system to adapt to varying conditions while managing complexity through automated determination algorithms
Solution Approach 2:
The patent applies parameter changes by modifying the notification target range parameter according to multiple input factors. The determination unit processes information attributes, traffic properties, and environmental state to adjust the transmission range parameter, enabling flexible information dissemination without requiring complex manual configuration
2Loss of information
If the roadside communication device transmits information to all vehicles within a wide range, then the information reaches more vehicles, but the information may not reach the most appropriate vehicle that needs it urgently
Solution Approach 1:
The patent applies local quality by determining different notification target ranges for different information attributes. Instead of using a uniform transmission range, the system adjusts the notification target range locally based on the specific information being transmitted, traffic conditions, and environmental factors, ensuring that information reaches the most appropriate vehicles with the required urgency
3Reliability
If the roadside communication device adjusts the transmission range based on multiple factors, then the information is transferred to the appropriate vehicle, but the processing complexity and computational load increase
Solution Approach 1:
The patent applies self-service by enabling the determination unit to automatically process information attributes, traffic properties, and environmental state to determine the appropriate notification target range without requiring external intervention or complex manual configuration. The system serves itself by making autonomous decisions about information dissemination parameters
Solution Approach 2:
The patent applies feedback by using real-time traffic properties and environmental state information to adjust the notification target range. The determination unit continuously monitors conditions and adjusts transmission parameters accordingly, creating a feedback loop that improves information transfer reliability while managing processing complexity through automated control
