Process for controlling closing movement of closing mechanisms with

Abstract

A process for controlling the closing movement of closing mechanisms with at least one electromotive part includes the following features to guarantee squeeze protection: the measured values of at least one motor performance characteristic which characterizes the load on the electric motor, are continuously recorded and evaluated, a continuously adapted tripping threshold defining a squeezing incident is specified for each motor performance characteristic, the measured values of each motor performance characteristic are compared with each tripping threshold and, if the tripping threshold is exceeded by at least one measured value, a defined reaction is initiated from the closing mechanisms. Immediately after the start of the closing movement, the starting behavior of the closing mechanism in the starting phase of the electric motor is defined with regard to equalization of drive play and sluggishness of the closing mechanism with reference to measured values of at least one motor performance characteristic relevant to the closing distance. This means that squeeze protection can be activated in the starting phase, relevant to the response relevant to the closing distance of at least one motor performance characteristic, when an activation value relevant to the closing distance is reached. Once squeeze protection has been activated in the starting phase, this additional response of at least one motor performance characteristic relevant to the closing distance is specified up to achieving uniform motion of the electromotive part, taking into consideration the measured values of at least one motor performance characteristic(s) of the previous and current closing movement and the tripping threshold of at least one motor performance characteristic is defined relevant to the given additional response of each motor performance characteristic relevant to the closing distance.
