A method of controlling a moving component (22, 24) approaching a buffer (42, 46) in a hoistway (34) of an elevator system (20) is provided. The method comprises: a) calculating, based on a current velocity of the moving component (22, 24), a required braking distance to decelerate the moving component (22, 24) to a maximum buffer impact velocity; b) comparing the required braking distance to a current buffer distance between the moving component (22, 24) and the buffer (42, 46) to give a comparison result; c) repeating steps a) and b) one or more times; and d) triggering an emergency stop of the moving component (22, 24) based on the comparison result.
