A method for centering a self-propelled elevator car in an elevator installation, the car having at least two driven friction wheels pressed against each of two opposing guide surfaces of a first and second guide rail strands to drive the car along a travel path, the method including independently adjusting a first rotational speed of the friction wheels acting on the first guide rail strand and a second rotational speed of the friction wheels acting on the second guide rail strand. In a centered state, a center of the car is located on a center plane extending in parallel with the first and second guide rail strands, and when a deviation of the car center from the center plane is detected, the first rotational speed and/or the second rotational speed is changed such that, when the car moves along the travel path, the car center moves toward the center plane.
