1. A travel support device comprising:
processing circuitry configured to
output a target speed of a merging vehicle that is going to change lanes to a merging destination lane;
acquire a current speed of the merging vehicle and calculate a first control amount that matches the current speed with the target speed;
acquire a position and a speed of at least one merging destination vehicle that is a vehicle traveling in the merging destination lane;
acquire a current position of the merging vehicle and calculate a second control amount that maintains a first inter-vehicle distance between the merging vehicle and the at least one merging destination vehicle by using a position of the merging vehicle, a position of the at least one merging destination vehicle, and a speed of the at least one merging destination vehicle;
acquire a speed of the merging vehicle and calculate a predicted position of the at least one merging destination vehicle in a case where it is assumed that the current speed of the merging vehicle has reached the target speed by using the speed of the merging vehicle, the target speed, the position of the at least one merging destination vehicle, and the speed of the at least one merging destination vehicle; and
output one of the first control amount and the second control amount by using the speed of the merging vehicle, the speed of the at least one merging destination vehicle, and the predicted position of the at least one merging destination vehicle.
