The invention discloses a control method capable of achieving direct stopping of an elevator. The method comprises the steps that in the running process of the elevator, the current position of an elevator lift car is calculated; after the elevator lift car enters a magnet vane, the theoretical position of the elevator lift car is calculated, and is compared with the current position of the elevator lift car, and the deviation between the theoretical position and the current position of he elevator lift car is obtained; and according to the deviation between the theoretical position and the current position of the lift car, the theoretical deceleration curve of the elevator is adjusted in a closed-loop manner on the basis of the position, and the elevator runs according to the curve. The problem that in he prior art, due to direct stopping caused by low-speed fluctuation of a motor, the story-aiming precision is low is solved.
