Abstract
The elevator car is arranged movably along guideways and in the special operating mode is decelerated to a standstill and kept at a standstill by a braking device, by a braking force brought about by the braking device together with a brakeway. A required deceleration to bring the elevator car to a standstill within a next-possible exit zone in the special operating mode is calculated, furthermore a stopping of the elevator car is detected if a sudden change in the braking force or the acceleration is established and the braking force of the braking device is set to a holding force when the stopping is established. The special operating mode results in 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.
