Abstract

A method for controlling a screwing process, includes during the screwing process screwing a screw into a component with an electrical screwing device; detecting during the screwing process an actual course of at least one process parameter of the screwing; testing whether the actual course has a pattern which predicts an error of the screwing process; and terminating the screwing process early when the actual course has said pattern.
