Abstract
A method to control a powertrain in a vehicle during an acceleration is provided, the powertrain including a propulsion unit, a multi-clutch transmission drivingly connected to the propulsion unit, and a control unit for controlling at least the powertrain components, which control unit is provided with a prediction model including at least one simulated shift sequence for the multi-clutch transmission. The method involves monitoring at least one operating parameter of the powertrain; estimating the time (tE) between initiation of a first power upshift and initiation of a sequential second power upshift using the prediction model; and, if the estimated time is shorter than a predetermined time limit (tLIM), controlling the propulsion unit to limit the vehicle acceleration so that the time between the first and second power upshifts is increased to be at least equal to the predetermined time limit (tLIM).
