Described is a control system for an elevator wherein the distance between the current car position and the target position of a floor at which the car is to be halted is detected on the basis of a car position signal computed from car displacements and a preliminarily stored floor position signal for controlling the car speed. According to the present invention, the contents of a read-only floor memory concerning the respective floor positions stated in the building plan or schedule are transferred at the outset into a transient read/write floor memory. In the course of the subsequent elevator car travel, the data in said transient floor memory is corrected through the learning of the contents of the car position signal computed during car displacements. In this manner, the car may be controlled to arrive at a target floor accurately despite occasional difference between the actual floor position and the design floor positions.
