V2P Communication Power Management via Location-Based Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In V2X communication, pedestrian communication devices face challenges with limited power capacity, making it difficult to ensure safety due to high power consumption.
Innovation Solution
The proposed solution involves an electronic device and method that activates or deactivates the communication function based on location, using position information to minimize power consumption by controlling communication functions, such as V2P communication, and implementing intermittent communication schemes like DRX and DTX to reduce power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X communication function is continuously activated to ensure safety, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the communication function switchable between activated and deactivated states based on location information. The system dynamically adjusts its operational state (communication active/inactive) according to the pedestrian's position, allowing the device to maintain reliability when needed while reducing power consumption when the communication function can be deactivated.
Solution Approach 2:
The patent changes the operational parameter of the communication function from a static continuous state to a dynamic state that varies based on location. By modifying the activation status parameter according to positional information, the system optimizes the balance between maintaining communication reliability and reducing power consumption.
2Reliability
If communication function is activated in all areas to ensure safety, then safety coverage is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by differentiating the communication function activation based on spatial location. The system determines whether to activate or deactivate communication based on the pedestrian's current position, applying the communication function selectively in specific areas rather than uniformly across all locations. This allows safety coverage to be maintained where needed while reducing power consumption in areas where communication can be deactivated.
