Abstract
A method for operating an elevator system with a car that moves in an elevator shaft may involve detecting an operating parameter related to a change in loading of the car, ascertaining whether a position of the car relative to a stopping floor needs to be adjusted based on the operating parameter, determining times at which the car is to be stopped and at which the adjustment is to be performed, stopping the car and blocking a flow of energy of a drive of the car and/or activating a service brake as the car is being stopped and/or while the car is stopped, and adjusting the position of the car if necessary. Further, whether the adjustment is necessary may be ascertained before the car is stopped.
