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

The invention relates to a method for operating an elevator system (1), which comprises a shaft system (2) and at least three cars (3) and which is designed for separately moving the cars (3) at least in a first direction of travel (4) and in a second direction of travel (5), wherein the at least three cars (3) are moved separately in sequential operation and, for each car (3), a stop point (6, 7) at which the car (3) can stop if necessary is continuously predicted at least for one direction of travel. The distance (8, 9) of the predicted stop points (6, 7) of adjacent cars (3) from each other is continuously determined, wherein the elevator system (1) is transferred to a safety mode if a negative distance (9) of the stop points (6, 7) is determined. The invention further relates to an elevator system designed for performing such a method. 本发明涉及种用于操作电梯系统(1)的方法，电梯系统(1)包括井道系统(2)和至少三个轿厢(3)，电梯系统(1)被设计成用于至少沿第行进方向(4)和沿第二行进方向(5)独立地移动轿厢(3)，其中，所述至少三个轿厢(3)以顺序操作被独立移动，并且对于每个轿厢(3)，至少针对个行进方向连续预测该轿厢(3)必要情况下能够停靠的停靠点(6，7)。连续确
