Abstract
A travel control device includes a first recognizer recognizing first travel environment information based on information acquired by an autonomous sensor, a second recognizer recognizing second travel environment information acquired by external communication, a main deceleration controller performing main deceleration control against an obstacle when it is determined, based on the first information, that the vehicle is traveling on a branch road merging with a main road and an obstacle may interfere with the vehicle at a merging point with the main road at a predicted time, and a preliminary deceleration controller performing preliminary deceleration control against the obstacle before the main deceleration control when it is determined, based on the second information, that the vehicle is traveling on the branch road, and the obstacle is to exist at the merging point at the predicted time and the obstacle is not recognized yet based on the first information.
