Description

Transmission instruction device and transmission instruction method Technical Field The present invention relates to a technique for performing in-vehicle communication by a plurality of communication apparatuses in the standard of ethernet (registered trademark). Background Patent document 1 discloses a mobile terminal having a communication unit capable of communicating with a vehicle and a server. The mobile terminal includes a synchronization processing unit configured to acquire information of an ECU mounted in a vehicle and transmit the information to a server, and a1 st acquisition unit configured to acquire software distributed from the server, and the mobile terminal transmits the software acquired by the 1 st acquisition unit to the vehicle via a communication unit. Patent document 1 Japanese patent laid-open No. 2024-66068 Disclosure of Invention The vehicles periodically transmit the vehicle data to the server device, but the number of vehicles that can communicate with the server device increases, and the transmission amount of the vehicle data per vehicle tends to increase. Therefore, it is preferable to suppress the communication load between the vehicle and the server apparatus. The present invention provides a technique for suppressing a communication load between a vehicle and a server device. In order to solve the above-described problems, a transmission instruction device according to one embodiment of the present invention includes an acquisition unit that acquires utilization information about a time when a vehicle is utilized, a learning unit that learns from the utilization information and outputs a utilization pattern indicating a utilization time of the vehicle, a determination unit that determines a transmission time when data of the vehicle is transmitted to a predetermined server device based on the utilization pattern, and an instruction unit that instructs the vehicle to transmit the vehicle data at the determined transmission time. Another aspect of the present invention is a transmission instruction method. The method is a transmission instruction method for executing steps by a computer, and the transmission instruction method includes the steps of acquiring utilization information about a time when a vehicle is utilized, learning based on the utilization information, outputting a utilization pattern indicating a utilization time of the vehicle, determining a transmission time for transmitting vehicle data of the vehicle to a predetermined server device based on the utilization pattern, and instructing the vehicle to transmit the vehicle data at the determined transmission time. Effects of the invention According to the present invention, a technique for suppressing a communication load between a vehicle and a server device can be provided. Drawings Fig. 1 is a diagram showing a basic configuration of a transmission instruction system of the embodiment. Fig. 2 is a diagram showing a functional configuration of a transmission instruction system of the embodiment. Fig. 3 is a flowchart of transmission instruction processing performed by the server apparatus of the embodiment. Fig. 4 is a flowchart of a transmission process performed by the vehicle control apparatus of the embodiment. Detailed Description Fig. 1 is a diagram showing a basic structure of a transmission instruction system 1 of the embodiment. The transmission instruction system 1 includes a server device 10, a1 st vehicle 12a, a2 nd vehicle 12b, and a 3 rd vehicle 12c. The 1 st vehicle 12a, the 2 nd vehicle 12b, and the 3 rd vehicle 12c (referred to as "vehicles 12" without distinguishing them) can communicate wirelessly with the server apparatus 10 via the network 14. In addition, the vehicle 12 is not limited to 3. The server apparatus 10 is not limited to 1 apparatus. The server device 10 is located at a position remote from the vehicles 12, collects vehicle data from the plurality of vehicles 12, and indicates a timing at which the vehicle data is transmitted to the plurality of vehicles 12.
