    摘要: The present invention relates to a method for controlling an operation of a multi-clutch transmission (100) operatively connected to a prime mover of a vehicle. The multi-clutch transmission (100) includes a dual-clutch assembly (10), a clutch input shaft (20) drivingly connected to the prime mover and a transmission output shaft (30).The dual-clutch assembly (10) is provided with a first clutch (12) and a second clutch (14) operatively connected to the clutch input shaft (20) and configured for transmitting a rotational torque of the clutch input shaft (M cis ); the first clutch (12) is operatively connected with a first input shaft (42) of a first sub-transmission (40) having a first set of gears (70), the first clutch (12) is transmitting a first rotational torque portion (Μ 1 ) of the rotational torque of the clutch input shaft (M cis ) to the first input shaft (42); the second clutch (14) is operatively connected with a second input shaft (52) of a second sub-transmission (50) having a second set of gears (80), the second clutch (14) is transmitting a second rotational torque portion (M 2 ) of the rotational torque of the clutch input shaft (M cis ) to the second input shaft (52), the method comprising the steps of: (a) engaging the first clutch (12), or the first clutch (12) and the second clutch (14), at a launch of the vehicle for transmitting a rotational torque (M output ) to the transmission output shaft (30) while a rotational speed of the first input shaft (42) is different from a rotational speed of the clutch input shaft (20); and (b) decreasing the initial amount of the first rotational torque portion (M 1 ) to a decreased amount and increasing the initial amount of the second rotational torque portion (M 2 ) to an increased amount while the rotational speed of the first input shaft (42) is different from the rotational speed of the clutch input shaft (20). The present invention also relates to a control unit (60) for a vehicle configured for implementing a method for controlling the operation of the multi-clutch transmission (100).
