摘要：A method of controlling a dual-clutch transmission having two partialtransmissions that can be connected to a drive engine such that a target gear, in arespective load-free partial transmission to be engaged following the currently active

gear, can be preselected. To reduce the energy consumption caused by transmissionlosses, the method includes the steps of: determining a possible target gear,

determining overall transmission losses for both when a target gear is preselected, andwhen a target gear is not preselected, determining whether the overall transmission lossis greater when a target gear is preselected or when no gear is preselected, decidingwhether a target gear should or should not be preselected using the overall

transmission loss determined as a criterion, and implementing measures that correspondto the decision reached.
