| description | An elevator control apparatus improves car position detection accuracy without increasing the number of sensors. A position detection sensor installed on a caroutputs a detection signal when an object installed in a hoistway is detected. A controller corrects a position of the car calculated on the basis of a pulse signal that an encoder which rotates in accordance with ascending and descending of the car outputs, in accordance with a position of the object to be detected. A storage device stores data on the position of the car calculated prior to a time point when the detection signal is received. A correction amount of the position of the car is calculated on the basis of a communication delay time and the data which is stored in the storage device, and the position of the car is corrected in accordance with the correction amount. |
