Abstract
A software update device updates software for an in-vehicle control device mounted in a vehicle. An information acquisition unit acquires, from a server provided outside the vehicle, update process information. The output unit outputs consent request information. The execution unit executes the update process. The calculation unit calculates an estimated time required for the update. The communication status acquisition unit acquires communication status information related to communication status with the server. The correction unit corrects the estimated time based on the communication status information. The notification unit outputs information on the corrected estimated time. The notification unit, when the corrected estimated time is shorter than the estimated time before correction, does not output information on the corrected estimated time.
