An adaptive method for controlling a vehicle speed and an adaptive device for using the same is disclosed. The method controls a vehicle speed of a host vehicle that is driving. A front vehicle drives in front of the host vehicle. There is a vehicle distance between the host vehicle and the front vehicle. Firstly, first accelerations of the host vehicle are retrieved and the vehicle speeds corresponding to the first accelerations and the vehicle distances corresponded thereof are retrieved. When all the first accelerations are not zero, the extreme values of the first accelerations are deleted. Finally, the vehicle speed of the host vehicle is controlled according to all the retrieved accelerations, their corresponding vehicle distances, and the vehicle speeds corresponded thereof.
