Abstract
A method for operating a drive device for a motor vehicle. The drive device has an internal combustion engine, an output shaft, and a clutch connected between the internal combustion engine and the output shaft. In a coasting operating mode, an idling speed control of the internal combustion engine to an idling speed is carried out and the clutch is opened, and, in an overrun operating mode, the clutch is closed. When shifting from the coasting operating mode to the overrun operating mode, while, at the same time, carrying out the idling speed control of the internal combustion engine to the idling speed, the clutch is closed, so that an entrainment of the internal combustion engine occurs.

A method for operating a drive device for a motor vehicle, wherein the drive device has an internal combustion engine, an output shaft, and a clutch connected between the internal combustion engine and the output shaft, and wherein, in a coasting operating mode, an idling speed control of the internal combustion engine to an idling speed is carried out and the clutch is opened and, in an overrun operating mode, the clutch is closed, wherein the clutch is closed when shifting from the coasting operating mode to the overrun operating mode, while, at the same time, carrying out the idling speed control of the internal combustion engine to the idling speed, so that an entrainment of the internal combustion engine occurs, and
- wherein the clutch is adjusted to a predetermined clutch torque that is transmitted between the internal combustion engine and the output shaft.
A drive device for a motor vehicle, comprising:
- an internal combustion engine, an output shaft, and a clutch connected between the internal combustion engine and the output shaft, wherein, in a coasting operating mode, an idling speed control of the internal combustion engine to an idling speed is carried out and the clutch is opened, and, in an overrun operating mode, the clutch is closed, wherein the drive device is designed to close the clutch when shifting from the coasting operating mode to the overrun operating mode, while, at the same time, carrying out the idling speed control of the internal combustion engine to the idling speed, so that an entrainment of the internal combustion engine occurs, and
- wherein the clutch is adjusted to a predetermined clutch torque that is transmitted between the internal combustion engine and the output shaft.
