PCT No. PCT/JP92/00441 Sec. 371 Date Mar. 10, 1993 Sec. 102(e) Date Mar. 10, 1993 PCT Filed Apr. 8, 1992.The present invention relates to a method of controlling a plurality of elevator cars disposed in a common hoistway. When the amount of time elapsed since a moving elevator has started is within a range which is determined by the position from which the moving elevator has started and the position from which a stopped elevator will start, a determination is made that there is the possibility that the two elevators move in parallel. Hence, the stopped elevator is prevented from starting. When such an amount of time is out of the range, a command is issued to start the stopped elevator. Thus, the stopped elevator is no longer prevented from starting when the amount of time elapsed since the moving elevator has started is out of the range within which the two elevators may move in parallel. The waiting time is minimized during which the elevator is prevented from starting, thus improving reliability.
