AI Technical Summary

Technical Problem

When a large number of vehicles are managed by a server, the excessive communication volume leads to increased communication costs, and existing technologies are unable to effectively reduce these costs.

Method used

By predicting the confidence level of the connection time between the vehicle and the power grid, the communication frequency with the vehicle is dynamically adjusted, and the communication frequency is reduced to decrease the amount of communication.

Benefits of technology

It effectively reduces communication costs, while improving the accuracy of connection timing prediction, reducing unnecessary data transmission, and saving communication expenses.

Abstract

This invention relates to a server, a vehicle, and a communication control method. Each of a plurality of vehicles is configured to be capable of at least one of charging and discharging with the power grid when electrically connected to it. A vehicle management server includes: a communication device for acquiring data including location information of a target vehicle (not connected to the power grid) via communication; and a processor for determining the communication frequency for acquiring data from the target vehicle. The processor acquires data from the target vehicle. The processor predicts the connection time based on the acquired data using a time prediction model that predicts the connection time when the target vehicle can connect to the power grid based on the data from the target vehicle, and calculates a confidence level for the predicted connection time. The processor determines the communication frequency based on the confidence level.
