摘要： A software update device is configured to update software for an in-vehicle control device mounted in a vehicle. The software update device includes an information acquisition unit, an output unit, an execution unit, a communication status acquisition unit, a correction unit, and a notification unit. The information acquisition unit is configured to acquire, from a server provided outside the vehicle, update process information related to an update of the software. The output unit is configured to output consent request information for asking a user whether to consent to the update of the software. The execution unit is configured to execute an update process for the software according to response information that is a response to the consent request information from the user. The calculation unit is configured to calculate an estimate time required for the update. The communication status acquisition unit is configured to acquire communication status information related to a communication status with the server. The correction unit is configured to correct the estimated time based on the communication status information. The notification unit is configured to output information on the corrected estimated time. The notification unit is configured to, when the corrected estimated time is shorter than the estimated time before correction, not output information on the corrected estimated time.
