Abstract
The present disclosure concerns a method for operating an elevator system which comprises a shaft system and at least three cars, which is designed for separately moving the cars in at least a first direction of travel and in a second direction of travel. The at least three cars are moved separately in sequential operation each time and for each car a stop point at which the car can stop if necessary is continuously predicted at least for one direction of travel. The distance of the predicted stop points of neighboring cars from each other is thereby continuously determined. The elevator system is transferred to a safety mode if a negative distance of the stop points is determined.
