Power Supply Vehicle Dispatch Under Traffic Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for battery electric vehicles (BEVs) face reliability issues in power supply during traffic congestion, where the battery power may not suffice to meet the demand, leading to potential stranding due to insufficient power delivery.
Innovation Solution
A server device manages communication between power supply vehicles and subject vehicles, instructing a first vehicle to move to a power supply location when traffic is lightly congested and a second vehicle with higher power generation capacity to move when traffic is heavily congested, utilizing both battery and power generation devices to ensure reliable power delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery-powered power supply vehicle is dispatched to supply power to a vehicle running out of power, then power supply can be provided, but the reliability of power supply is insufficient under high traffic congestion conditions
Solution Approach 1:
The system changes the parameter of power generation capacity by selecting different types of power supply vehicles based on traffic conditions. Under high congestion conditions, it selects vehicles with higher power generation capacity (such as hybrid vehicles or vehicles with larger batteries) to ensure reliable power supply, while under light congestion conditions, it uses standard battery-powered vehicles.
2Reliability
If a power supply vehicle with higher power generation capacity is used, then power supply reliability improves, but vehicle selection and dispatch complexity increases
Solution Approach 1:
The vehicle dispatch system dynamically adjusts its operation based on real-time traffic conditions. The server receives traffic information, determines the congestion level, and accordingly selects the appropriate type of power supply vehicle. This dynamic adaptation allows the system to maintain high reliability without requiring a permanently complex dispatch structure.
Solution Approach 2:
The system incorporates feedback mechanisms by continuously monitoring traffic conditions and using this information to make informed decisions about vehicle dispatch. The server receives real-time traffic data, processes it to determine congestion levels, and adjusts vehicle selection accordingly, creating a closed-loop control system that improves reliability while managing complexity.

AI summary
The server device includes a communication unit and a control unit that performs communication using the communication unit. The control unit sends a movement instruction to the first power supply vehicle to the position of the power supply vehicle when the traffic situation around the power supply vehicle that requires power supply is a first situation. When the traffic situation is a second situation where the degree of congestion is higher than the first situation, the control unit causes a second power supply vehicle having a higher power generation capacity than the first power supply vehicle to move to the position of the power supplied vehicle.
