Method for preselecting a gear in a multi-clutch transmission of a vehicle upon exiting free-wheeling state
Abstract:
A method is provided for preselecting a gear in a multi-clutch transmission of a vehicle upon exiting free-wheeling state, wherein the multi-clutch transmission being operated in a free-wheeling state having a gear of a first set of gears preselected and a first friction clutch being disengaged; the method including the steps of: A) upon determining that at least one predetermined condition for exiting free-wheeling state is met; increasing the rotational speed of the prime mover towards a rotational synchronization speed of the preselected gear; the second friction clutch being in a closed state such that the rotational speed of the input shaft of the second friction clutch increases with the increasing rotational speed of the prime mover; B) disengaging the second friction clutch; C) engaging, at a suitable time point, at least one tooth clutch of the second subset of the tooth clutches corresponding to a gear of the second set of gears such that the gear of the second set of gears becomes preselected.
