Zusammenfassung:	ELEVATOR SYSTEM An elevator system including an elevator car mounted for movement in a building to serve the floors therein. The deceleration control for stopping the elevator car accurately at a selected floor, regardless of load and direction of the elevator car, continuously adjusts the braking torque to provide the desired velocity versus time pattern, and the desired distance versus time pattern, wherein both the deceleration distance and the deceleration time are fixed quantities.
