The operation of assemblies of the motor vehicle is controlled and/or regulated by taking into account a loss torque of the drivetrain, such that when a defined first operating condition of the motor vehicle is fulfilled, then as a function of a torque of a drive aggregate (1) of the drivetrain, as a function of a drag torque of a transmission (3) of the drivetrain, and as a function of a first sum of known loss torques of the drivetrain, a second sum of the unknown loss torques of the drivetrain is determined. Thereafter, the operation of assemblies of the motor vehicle is controlled and/or regulated taking into account the first sum of the known loss torques and taking into account the second sum of the unknown loss torques.
