An automatic following travel system initiates travel in file of a group of vehicles on an inclined path while maintaining a constant distance between the vehicles. During the initiation of travel in file, a travel ECU in a leading vehicle sends a directive indicating that travel in file is to be conducted to the following vehicles. Based on this directive from the leading vehicle, the travel ECUs of each of the following vehicles makes a determination as to the possibility of travel of their own vehicle, and control the movement of their own vehicle so that an approximately constant distance is maintained between their own vehicle and another vehicle positioned in front, thereof. The results of the determination of the possibility of movement are communicated to the leading vehicle. The travel ECU of the leading vehicle sends a directive indicating the release of the parking lock to the following vehicles when determinations that travel is possible have been sent from all following vehicles. Based on the directive from the leading vehicle, the travel ECUs of the following vehicles release the parking lock, and initiate the forward progress of the following vehicles in response to the leading vehicle.
