ABSTRACT:
The invention relates to a procedure for stopping an elevator car at a landing, in which procedure the travelling velocity and position of the elevator in the shaft are measured and a distance from the landing, i.e. a deceleration point at which deceleration is started, is determined for one travelling velocity, i.e. a reference velocity. According to the invention, the deceleration point is changed in proportion to the difference between the measured travelling velocity and the reference velocity.
