Roadside Power Lane Control Using Travel-State Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply control devices fail to stabilize the overall electric power balance in systems that include power supply lanes and vehicles, as they only control the amount of electric power received by vehicles without considering the travel state information of multiple lanes.
Innovation Solution
A power supply control device that acquires travel state information of vehicles across multiple power supply lanes and sets a priority level for power supply based on this information to manage power distribution effectively during power shortages, ensuring balanced power distribution across all lanes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control device only controls the amount of electric power received by a vehicle, then the vehicle's power reception is optimized, but the overall electric power balance in the power supply system cannot be stabilized
Solution Approach 1:
The control device segments the power supply system into multiple controllable units (power supply lanes) and manages each lane independently based on its specific travel state information. This allows the system to stabilize overall power balance by controlling individual lane power transmission separately, rather than treating the entire system as a single unit.
Solution Approach 2:
The control device performs preliminary actions by acquiring travel state information (such as vehicle presence, speed, and power demand) before adjusting power transmission. This advance information gathering enables the system to proactively stabilize power balance across multiple lanes before power imbalances occur, rather than reacting after problems arise.
2Loss of energy
If the control device reduces electric power transmitted to a vehicle, then excessive power reception is prevented, but power distribution across multiple power supply lanes becomes unbalanced
Solution Approach 1:
The control device applies local quality by adjusting power transmission levels individually for each power supply lane based on its specific conditions (vehicle presence, travel state, power demand). Instead of uniformly reducing power across all lanes, the system selectively controls power transmission in specific lanes where it is needed, preventing both power waste and imbalance.
Solution Approach 2:
The control device implements feedback mechanisms by continuously monitoring travel state information from vehicles and power consumption data from each lane. This feedback enables the system to dynamically adjust power transmission levels to prevent both excessive power reception (reducing waste) and power imbalance (maintaining stability) across the multi-lane system.

AI summary
The power supply control device according to the present disclosure is provided on a road side, and is a power supply control device that controls a power supply lane that supplies power to a vehicle, and includes a processor, wherein when a power shortage occurs in a power supply area by the power supply lane, the processor acquires travel state information of the vehicle in a plurality of power supply lanes managed by the power supply control device, and sets a priority level for power supply to each power supply lane based on the travel state information.
