The present invention relates to a travel control device for automatic drive vehicle, and provides a vehicle travel control device that does not require visual notification to other vehicles and that causes no sense of discomfort in any of passengers on a host vehicle or other vehicles around the host vehicle with respect to a preliminary operation of the host vehicle. A vehicle travel control device (10) that causes various devices assisting the driving of the host vehicle to perform a preliminary operation to prepare for a possible future event is provided with an external information acquisition unit (1), a host vehicle information acquisition unit (2), another vehicle information acquisition unit (3) that acquires other vehicle information including whether another vehicle has an automatic drive function, and a preliminary operation control unit (5) that calculates a preliminary operation control amount for the various devices. In accordance with the determination as to whether the other vehicle is automatically driving, the preliminary operation control unit (5) determines the need for an adjustment in the preliminary operation control amount. If the adjustment is not required, the preliminary operation control unit (5) maintains the preliminary operation control amount as a final preliminary operation control amount. If required, the preliminary operation control unit adjusts the preliminary operation control amount to obtain a final preliminary operation control amount for the execution of the preliminary operation of the devices.
