Embodiment Construction

[0030] figure 1 A schematic diagram is shown of a drive train 1 , for example for a motor vehicle, which in the embodiment shown here is a hybrid drive. Accordingly, the power transmission device 1 has at least two power devices, namely, the first power device 2 and the second power device 3 . For example, the first power unit 2 is an internal combustion engine, and the second power unit 3 is an electric motor.

[0031] The two drive units 2 and 3 can be rigidly and / or permanently connected to each other via the shaft 4 . However, it is also possible to assign a separating clutch to the shaft 4 , by means of which the operative connection between the drive units 2 and 3 can be disconnected. The second drive unit 3 or the electric machine is actuated by means of power electronics 5 , which itself is actuated, for example, by means of a controller.

[0032] The drive train 1 also has a clutch 6 , in particular a starter clutch, and a transmission 7 , in particular a transmiss...

Abstract

The invention relates to a method for operating a drive device (1) for a motor vehicle, wherein the drive device (1) comprises an internal combustion engine (2), an output shaft and a clutch (6) connected between the internal combustion engine (2) and the output shaft, and wherein in a coasting mode an idle-running control of the internal combustion engine (2) is guided to an idling speed and the clutch (6) is opened, and in an overrun mode the clutch (6) is closed. When there is a switching from the coasting mode into the overrun mode when the idle-running control of the internal combustion engine (2) is simultaneously guided to the idling speed, the clutch (6) is closed so that the internal combustion engine (2) is tow-started. The invention further relates to a drive device (1) for a motor vehicle.

Description

technical field [0001] The invention relates to a method for operating a power transmission of a motor vehicle, the power transmission having an internal combustion engine, an output shaft and a clutch coupled between the internal combustion engine and the output shaft, the idle speed of the internal combustion engine being regulated in order to turn it off during coasting operation Adjust to idle speed and disengage the clutch, and engage the clutch when dragging. Furthermore, the present invention relates to a power transmission device. Background technique [0002] For example, a power transmission device is used to drive a motor vehicle, ie to provide a torque for driving the motor vehicle, which torque may also be referred to as drive torque. In order to provide drive torque, the drive train has at least one drive unit, for example an internal combustion engine. It goes without saying that the drive train can also have several, preferably different drive units, so tha...
