The Conference for Drivetrain and Systems Engineering Conference (DSEC, formerly ATK)  was first organized by the Association of German Engineers (VDI) in 1984 and has been held bi-annually from 1987 to 2021.

Since 2013 ATK is being hosted together with the Conference for Wind Power Drives (CWD).

With a topical integration of systems engineering today, the conference has been renamed to DSEC and is hosted and organized by the Center for Systems Engineering and the FVA GmbH.
