Abstract
This software control device is connected to a server by radio communication and controls updating or addition of software of an in-vehicle ECU. A management ECU 30 predicts a travel plan of a vehicle on the basis of history information regarding the travel history of the vehicle and / or the operation history of an in-vehicle device, and determines an installation schedule for installation processing on the basis of the travel plan such that the installation processing is executed when the vehicle is in a state suitable for the installation processing.
