摘要: 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.

摘要: A method to control an electric motor including the steps of: determining a target torque; calculating a target current by dividing the target torque by a torque constant; determining an equivalent impedance by means of a predetermined map; calculating the voltage drop by multiplying the target current by the equivalent impedance; calculating a counter-electromotive force by multiplying an actual rotation speed by a speed constant; determining a control voltage to be applied to the power supply terminals of the electric motor by adding the voltage drop to the counter-electromotive force; determining an offset parameter; and correcting the equivalent impedance provided by the predetermined map by applying the offset parameter.

摘要: 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; filling with oil, always supplying the maximum possible oil flow rate, a second clutch associated with the following gear after receiving the gear-shift command; completely closing the second clutch at the maximum possible speed as soon as the oil filling ends; and completely opening a first clutch associated with the current gear A at the maximum possible speed as soon as the oil filling in the second clutch ends.

摘要: A method to control an electric motor of a hydraulic system of a transmission in a vehicle; the hydraulic system has a circulation pump, which allows a lubricant oil to circulate, and/or an actuation pump, which provides the hydraulic pressure needed to operate the transmission, a carrier shaft on which the pumps are mounted, and the electric motor designed to cause the rotation of the carrier shaft; the steps provided are: determining a requested torque to be applied by the electric motor to the carrier shaft; determining a requested rotation speed to be imparted by the electric motor to the carrier shaft; and controlling the electric motor so as to pursue the requested torque and the requested rotation speed.
