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.

Method for operating an elevator system and elevator system designed for performing the method

The disclosure relates to an elevator system consisting of a plurality of elevator carriages, a shaft system, a drive system for separately moving the elevator carriages within the shaft system, as well as a safety system having a plurality of safety nodes designed to bring the elevator system into a safe operating mode if an operating mode of the elevator system, which deviates from the normal operation mode, is detected. The elevator carriages, the shaft system and the drive system form a functional unit. One of the safety nodes is always assigned to one of the functional units, wherein the safety nodes are each connected to at least another safety node through an interface for transmitting data. Each safety node includes at least one sensor, which detects an operating parameter of the corresponding assigned functional unit. A control unit evaluates the operating parameter detected by one of the sensors of the respective safety node and, taking into account the data transmitted by at least another safety node.
