Abstract
The invention relates to a method and an apparatus for controlling advance opening of doors in a double-deck elevator, in which elevator a car frame (2) supporting the elevator cars (1a and 1b) is moved by means of a set of hoisting ropes (3) by a hoisting machine (46) provided with a traction sheave. When the elevator is approaching the target floor levels (51, 52), the velocity of the elevator cars (1a and 1b) in the car frame (2) in relation to the car frame (2) is measured and, based on the measurement result, the velocity of the elevator cars (1a and 1b) relative to the floor levels (51, 52) is calculated.

Method for controlling advance opening of doors in a double-deck elevator, in which elevator a car frame (2) supporting the elevator cars (1a and 1b) is moved by means of a set of hoisting ropes (3) by a hoisting machine (46) provided with a traction sheave, characterized in that, at least when the elevator is approaching the target floor levels (51, 52), the velocity of the elevator cars (1a and 1b) in the car frame (2) in relation to the car frame (2) is measured and, based on the measurement result, the velocity of the elevator cars (1a and 1b) relative to the floor levels (51, 52) is calculated.
Apparatus for controlling advance opening of doors in a double-deck elevator, said elevator comprising a hoisting machine (46) which is provided with a traction sheave and which, by means of a set of hoisting ropes (3), moves a car frame (2) supporting the elevator cars (1a and 1b), and said apparatus comprising at least measuring means for the measurement of velocity (V) of the car frame (2) in relation to the floor levels (51, 52), characterized in that the apparatus comprises at least measuring means (50) for measuring the velocities (Va and Vb) of the elevator cars relative to the car frame (2).
