Clutches` actuating method for motor vehicle, involves triggering clutches during start of motor vehicle, such that clutches simultaneously and continuously transmit torque between drive shaft and output shaft

摘要

The method involves triggering clutches (16, 18) during start of a motor vehicle, such that the clutches simultaneously and continuously transmit torque between a drive shaft (24) and an output shaft (26). Capacity of each clutch is used as a control variable during starting of the motor vehicle for regulation of the speed of the drive shaft and/or the driving torque in a control circuit. The rotational speed of the drive shaft is greater than or equal to the rotational speed of a transmission input shaft in a partial train during the start of the vehicle. An independent claim is also included for a transmission control unit for actuating clutches in a drive train of a motor vehicle.
