To enable a vehicle to travel even during installation of new software in an ECU which controls travel of the vehicle and in which OTA is implemented.SOLUTION: When a control signal instructing travel of a vehicle is received during execution of installation of software for updating an ECU (Electronic Control Unit) for vehicle travel control that controls travel of the vehicle, a vehicle control device controls the vehicle so as to be capable of traveling according to a temporary travel mode for enabling the vehicle to travel in a mode different from a normal travel mode using the ECU for vehicle travel control.SELECTED DRAWING: Figure 2 【課題】車両走行を制御するＥＣＵにおいてＯＴＡが実施され、そのＥＣＵにおいて新たなソフトウェアがインストールされている最中であっても、車両を走行させることができる。【解決手段】車両制御装置は、車両走行を制御する車両走行制御用ＥＣＵ（Ｅｌｅｃｔｒｏｎｉｃ Ｃｏｎｔｒｏｌ Ｕｎｉｔ）を更新するためのソフトウェアのインストールが実行されている最中に、車両の走行を指示する制御信号を受け付けた場合、車両走行制御用ＥＣＵを用いた通常走行モードとは異なる態様で車両を走行させる臨時走行モードにより車両を走行可能に制御する。【選択図】図２
