Abstract

A method for activating a switching element of a valve device between a first end position and a second end position in which method an application device acts on the switching element in a first direction towards the first end position and in which an electromagnetic activation device acts on the switching element in a second direction towards the second end position when first energization occurs wherein the second direction is opposite to the first direction and in a normal mode within a cycle after an end of the first energization a movement of the switching element in the first direction brought about by the application device is slowed down by a brief second energization ('braking pulse') which is initiated after the expiry of a pause time after a characteristic time within the cycle. It is proposed that the optimum pause time and/or an optimum variable characterizing the braking pulse is determined in an adaptation mode as follows: a. initiation of a third energization instead of the second energization wherein the level of the third energization is on the one hand selected to be so low that the switching element cannot be moved out of the first end position when it is in said position and on the other hand is selected to be so high that the switching element does not leave the second end position when it is in said position and wherein the characteristic time is an end of the first energization and the pause time is firstly selected such that the switching element reliably moves into the first end position after the end of the first energization and before the start of the third energization b. shortening of the pause time from cycle to cycle c. determination of a minimum pause time during which the switching element no longer moves into the first end position after the start of the third energization d. adaptation of the pause time and/or of the variable which characterizes the braking pulse as a function of the minimum pause time determined.
