Abstract
In a multi-car elevator, when two adjacent cars travel in a like direction, an elevator controlling apparatus: determines a shortest stopping position that is a stopping position at which a leading car stops in a shortest stopping distance from its present position; determines an estimated stopping position that is a stopping position of a trailing car if the trailing car is stopped urgently when the trailing car deviates from a speed change path for stopping using decelerating control by the elevator controlling apparatus from its present position and approaches the leading car; and controls a separating distance between the leading car and the trailing car such that the estimated stopping position is before the shortest stopping position.
