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 transmission comprises a dual-clutch gearbox having two primary shafts, at least one secondary shaft connected to drive wheels, and two clutches, each of which is interposed between a drive shaft of an engine and a corresponding primary shaft; 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; and controlling, in case of downshifting, 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; the control method is characterized in that it comprises, in case of downshifting, the further steps of: determining whether a driving style is a comfort driving style, an energy efficiency driving style, a sports driving style or a racing driving style; activating the engine to generate a torque and so as to enhance the noise of the exhaust after the complete opening of the first clutch and so as to synchronize the speed (ω E) of rotation of the drive shaft with the speed (ω B) of rotation imposed by the gear ratio of the following gear only in case of sports or racing driving style; and not activating the engine to generate a torque after the complete opening of the first clutch and before the complete closing of the second clutch in case of comfort or energy efficiency driving style. receiving a gear-shift command; opening a first clutch associated with the current gear; closing a second clutch associated with the following gear; and controlling, in case of downshifting, 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; the control method is characterized in that it comprises, in case of downshifting, the further steps of: determining whether a driving style is a comfort driving style, an energy efficiency driving style, a sports driving style or a racing driving style; activating the engine to generate a torque and so as to enhance the noise of the exhaust after the complete opening of the first clutch and so as to synchronize the speed (ω E) of rotation of the drive shaft with the speed (ω B) of rotation imposed by the gear ratio of the following gear only in case of sports or racing driving style; and not activating the engine to generate a torque after the complete opening of the first clutch and before the complete closing of the second clutch in case of comfort or energy efficiency driving style. determining whether a driving style is a comfort driving style, an energy efficiency driving style, a sports driving style or a racing driving style; activating the engine to generate a torque and so as to enhance the noise of the exhaust after the complete opening of the first clutch and so as to synchronize the speed (ω E) of rotation of the drive shaft with the speed (ω B) of rotation imposed by the gear ratio of the following gear only in case of sports or racing driving style; and not activating the engine to generate a torque after the complete opening of the first clutch and before the complete closing of the second clutch in case of comfort or energy efficiency driving style.
