METHOD FOR CONTROLLING AND REGULATING A DRIVE TRAIN

摘要

The invention relates to a method for controlling and regulating a drive train of a vehicle comprising a drive-line, a transmission and an output. The transmission comprises controllable free-wheel devices, which correspond with toothed wheel pairings and which are provided for disengaging or engaging a previous or a new gear, and comprises a clutch mounted on the input side. In the occurrence of a shifting signal for executing a pull upshifting, a driving torque of the drive-line is rapidly reduced whereby inducing a first vibration in the drive train. During a subsequent shifting, an active connection between a free-wheel device and a toothed wheel pairing of the new gear, said toothed wheel pairing corresponding with the free-wheel device, is abruptly established whereby producing, in the drive train, a second vibration that counteracts the first vibration. The engagement of the new gear enables a disengagement of the active connection of the previous gear due to a torque reversal from a pull torque to a push torque.
