METHOD FOR THE ACTUATION OF AT LEAST TWO CLUTCHES TRANSMITTING TORQUE IN PARALLEL IN THE DRIVE TRAIN OF A MOTOR VEHICLE, AND TRANSMISSION CONTROL UNIT

摘要

The invention relates to a method for actuating at least two clutches (16, 18) which transmit torque in parallel in the drive train (10) of a motor vehicle (1) and are provided with different successive fixed speed transmissions (I1, I2) as gear stages (20, 22) between a drive shaft (24) and an output shaft (26). The clutches are triggered in such a way during acceleration processes and particularly during starting of the motor vehicle that both clutches (16, 18) simultaneously transmit torques and a resulting transmission of torque takes place continuously between the drive shaft (24) and the output shaft (26). According to the invention, the rotational speed (omega1) of the drive shaft (24) is greater than the respective rotational speed (omega31 or omega32) of the respective transmission input shaft of the respective partial train (12, 14) at the secondary end of the respective clutch (16, 18) during the entire starting process, or the rotational speed (omega1) of the drive shaft (24) is greater than or the same as the respective rotational speed (omega31 or omega32) of the respective transmission input shaft of the respective partial train (12, 14) at the secondary end of the respective clutch (16, 18) during an acceleration process.
