To make it possible to continue a calculation in a vehicle before a communication is interrupted.SOLUTION: A server device is comprised of: an arithmetic unit that communicates with an on-vehicle terminal and performs an operation by using information received from the on-vehicle terminal; a transmission unit that transmits the calculation result to the on-vehicle terminal as a perceptual signal that is a signal including at least one of audio and video; an interruption estimation unit that estimates a risk of interruption of communication with the on-vehicle terminal; and an on-vehicle execution application providing unit that transmits an execution code, which is information capable of executing a calculation equivalent to a calculation when the risk exceeds a first threshold, to the on-vehicle terminal.SELECTED DRAWING: Figure 2

    【課題】通信が途絶する前に車両内で演算を継続できる。【解決手段】サーバ装置は、車載端末と通信し、車載端末から受信する情報を用いて演算を行う演算部と、演算の結果を音声および映像の少なくとも一方を含む信号である知覚信号として車載端末に送信する送信部と、車載端末との通信が途絶するリスクを推定する途絶推定部と、リスクが第1の閾値を超えると演算と同等の演算が実行可能な情報である実行コードを車載端末に送信する車載実行アプリ提供部と、を備える。【選択図】図2
