Abstract
A control method for carrying out a gear shift in a transmission provided with a dual-clutch gearbox, so as to shift from a current gear to a following gear; the control method comprises the steps of: receiving a gear shift command; opening a first clutch associated with the current gear; closing a second clutch associated with the following gear; determining whether a driving style is a comfort driving style, an energy efficiency driving style, a sports driving style or a racing driving style; and in case of upshifting, controlling the second clutch after the complete closing of the second clutch, so as to allow said second clutch to temporarily transmit a torque that is greater than the torque to be transmitted by the second clutch immediately after the gear shift and than the torque transmitted by the first clutch immediately before the gear shift, only in case of energy efficiency or racing driving style.
