Abstract

See full text

A method is disclosed for operating a drivetrain of a working machine with a continuously variable transmission. The method comprises a step of detecting a current drive output rotation speed (10). The drivetrain is controlled (14) in such manner as to simulate a drivetrain with a fixed-gear transmission and a bridged converter transmission when the drive output rotation speed detected is higher than or equal to a drive output rotation speed limit. The drivetrain is controlled (16) in such manner as to simulate a drivetrain with a fixed-gear transmission and a coupled converter transmission when the drive output rotation speed detected is lower than the drive output rotation speed limit. In addition, the invention relates to a control unit for a drivetrain of a working machine with a continuously variable transmission, and a drivetrain for a working machine.
