Abstract

During a shift from a first driving range to a second driving range in a continuously variable power-split transmission having a continuously variable branch and a mechanical branch, in which during the range shift, the synchronous rotation speed is kept constant, the range shift is discontinued if a predefined threshold of at least one driving requirement is exceeded.
