Embodiment Construction

[0017] figure 1 A driveline 100 of a vehicle is shown. The drive unit 101 is in particular an internal combustion engine, an electric motor or a hydraulic motor, which is connected via a separating clutch 103 and subsequently a transmission 104 to a drive shaft 105 and the drive wheels. At least one mechanism is provided, in particular a control device 102, which exchanges data with components of the drive train, in particular with clutches and / or drive units of the transmission, and triggers at least one of these components, in particular provided for triggering the drive unit (101 , 301, 307) the rate of change of the torque increase and / or torque decrease of the drive torque.

[0018] figure 2 A schematic flow chart of an exemplary embodiment of a method according to the invention for operating a drive train of a vehicle is shown. The method starts with step 201 . In step 202 the current and requested drive torque is read in. Depending on whether the required drive to...

Abstract

The invention relates to a method and to a device for operating a drive train (100, 300) for a vehicle, wherein the drive train comprises at least one drive unit (101, 301, 307), which is suitable for outputting a drive torque. The rates of change for controlling a torque increase and a torque reduction of the drive torque of the at least one drive unit (101, 301, 307) are specified. This occurs in such a way that the specifiable rates of change of the torque increase and the torque reduction of the drive torque of the at least one drive unit (101, 301, 307) are different.

Description

technical field [0001] The invention relates to a method and a device for operating a drive train of a vehicle. Background technique [0002] Method for operating a drive train of a vehicle, wherein the drive train has at least one drive unit which is suitable for outputting a drive torque. DE 10 2005 060 858 discloses a method for operating a vehicle in which the actual torque of the drive unit is influenced via a reference filter. Rapid load changes or gear shifting processes trigger vehicle jerks, wherein typically the motor rotating mass, together with the transmission rotating mass, oscillates towards the reduced vehicle mass. Furthermore, other vibration patterns are also possible. Known methods for reducing jerk are based on avoiding excitation of the powertrain by rapid load changes. For this purpose, in the case of rapid changes, the torque requested by the driver via the accelerator pedal is low-pass filtered by means of a reference filter and the rate of change...
