An elevator system includes a car traveling up and down along a hoistway; a buffer for stopping the car at an end of the hoistway; brakes for braking travel of the car; a car traveling-information acquisition mechanism for acquiring information as to speed of the car; and a brake control unit for controlling the brake by comparing a speed of the car with a speed pattern curve created based upon a speed curve of the car when braking force is forcedly exerted by the brakes to enable the buffer to absorb a shock at the collision of the car with the buffer to a level below a predetermined specified value.
