ABSTRACT:
In an elevator apparatus, a control device obtains car information including at least one of car position information and car speed information based on a main detection signal from a main sensor unit. An auxiliary sensor unit detects arrival of a car at a preset reference position with in a hoistway to generate an auxiliary detection signal. The control device makes corrections to the car information based on the auxiliary detection signal.
