METHOD FOR CONTROLLING AND REGULATING A DRIVE TRAIN |
摘要 |
Described is a method for controlling and regulating a drive train of a vehicle comprising one drive unit, one transmission and one output unit. The transmission has controllable free-wheel device corresponding with toothed wheel pairs for disconnecting or connecting an old or a new gear and located on the input side one clutch. In the presence of a shifting signal for carrying out a higher traction shift, an input torque of the drive unit is quickly reduced so that a first vibration is induced in the drive unit. During a subsequent shifting, an operative connection is abruptly created between a free-wheel device and a toothed wheel pair corresponding therewith in a manner such that a second vibration counteracting the first vibration is produced in the drive train. With the engagement of the new gear the operative connection of the old gear is canceled as a result of a torque reversal from a pull torque to a push torque. |
