Abstract
A dialog confirmation unit in a vehicle communication device calculates the deceleration of a vehicle on the basis of vehicle speeds, when the vehicle speed at an operation start time and the vehicle speed at a time when a certain time has elapsed since the operation start time have been obtained by a vehicle information acquisition unit. Next, the dialog confirmation unit calculates a change in distance on the basis of distances when a distance information acquisition unit has obtained the distance between the vehicle and an object in front at the operation start time and the distance at the time when a certain time has elapsed since the operation start time. Next, the dialog confirmation unit selects a dialog that corresponds to the deceleration and the change in distance, from among a plurality of dialogs.
