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 a special operating mode

摘要

The invention relates to an elevator system with an elevator car, a braking devicefor stopping an elevator car in a special operating mode and a method for stoppingan elevator car in the special operating mode. The elevator car (2) is arrangedmovably along guideways (4) and in the special operating mode is deceleratedto a standstill and kept at a standstill by a braking device (3), by means of a brakingforce (FB) brought about by the braking device (3) together with a brakeway (5). According to the invention, a required deceleration (ANe) to bring the elevatorcar (2) to a stand still within a next-possible exit zone (11) in the special operatingmode is calculated, furthermore a stopping of the elevator car (2) is detectedif 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 holdingforce when the stopping is established. Use of the invention follows from theelevator car coming to a stop directly in the region of an exit zone in a specialoperating mode and passengers in the car being able to leave the elevator car independently.
