Abstract
The invention relates to an elevator system with an elevator car, a braking device for stopping an elevator car in a special operating mode and a method for stopping an elevator car in the special operating mode. The elevator car (2) is arranged movably along guideways (4) and in the special operating mode is decelerated to a standstill and kept at a standstill by a braking device (3), by means of a braking force (FB) brought about by the braking device (3) together with a brakeway (5). According to the invention, a required deceleration (ANe) to bring the elevator car (2) to a stand still within a next-possible exit zone (11) in the special operating mode is calculated, furthermore a stopping of the elevator car (2) is detected if a sudden change (dFBeff) in the braking force (FB) or the acceleration (Aeff) is established and the braking force (FB) of the braking device (3) is set to a holding force when the stopping is established. Use of the invention follows from the elevator car coming to a stop directly in the region of an exit zone in a special operating mode and passengers in the car being able to leave the elevator car independently.
