FIELD: transport.
SUBSTANCE: invention relates to method and system of double-clutch transmission control. Control method includes following steps: use of control unit to control internal combustion engine and transmission; use of prediction model containing one simulated sequence of transmission shifts; predicting time gap (Δt) between the first and the second transmission shifts under load to higher gear or between the first and the second transmission shifts under load to lower gear based on one prediction model; change of one transmission control parameter if predicted time gap between the first and the second transmission shifts under load to higher/lower gear is smaller than preset time gap limit value. Control system contains transmission control unit. The control unit is programmed for executing above mentioned method.
EFFECT: higher driving comfort.
