Abstract

A method for controlling dual clutch transmission with at least two partial drive trains, each arranged to be coupled with an engine by means of a clutch, in that, a first clutch of an actively operated partial drive train currently transmitting torque is opened, whereas a second clutch of the partial drive train not actively operated is closed in the already engaged gear and determining a reduction of a maximum possible lateral guiding force of at least one drive wheel and determining torque transmitted by the clutches, wherein, in the case of reduction of the maximally possible lateral guiding force below a default value and in the case that torque is transmitted by both clutches, the torque of one of the clutches is reduced.
