Abstract
A drive train for a vehicle includes at least one transmission having a primary input shaft designed to be connected to a primary drive, a secondary input shaft designed to be connected to a secondary drive, an output shaft designed to output power that has been introduced into the at least one transmission by the primary input shaft, and a planetary gearbox designed to continuously variably set a transmission ratio between the primary input shaft and the output shaft on the basis of the rotational speed of the secondary input shaft. The invention further relates to a vehicle having a drive train of this type, to a method for controlling a drive train of this type, and to a computer program product.

A drive train for a vehicle, comprising:
- at least one transmission, the at least one transmission including
- a primary input shaft configured to connected to a primary drive,
- a secondary input shaft configured to be connected to a secondary drive,
- an output shaft configured to output power introduced into the at least one transmission by the primary input shaft, and
- a planetary gear train configured to steplessly adjust a translation ratio between the primary input shaft and the output shaft in response to changes in a rotation speed of the secondary input shaft.
A vehicle having a drive train, comprising:
- at least one transmission, the at least one transmission including
- a primary input shaft configured to connected to a primary drive,
- a secondary input shaft configured to be connected to a secondary drive,
- an output shaft configured to output power introduced into the at least one transmission by the primary input shaft, and
- a planetary gear train configured to steplessly adjust a translation ratio between the primary input shaft and the output shaft in response to changes in a rotation speed of the secondary input shaft,
- wherein the output shaft of the at least one transmission is connected to at least one wheel of the vehicle directly or via intermediate elements.
A method for controlling a drive train having at least one transmission, the at least one transmission including a primary input shaft configured to connected to a primary drive, a secondary input shaft configured to be connected to a secondary drive, an output shaft configured to output power introduced into the at least one transmission by the primary input shaft, and a planetary gear train configured to steplessly adjust a translation ratio between the primary input shaft and the output shaft in response to changes in a rotation speed of the secondary input shaft, comprising the acts of:
- applying power to the primary input shaft of the at least one transmission;
- determining a required rotation speed of the secondary input shaft of the at least one transmission to set a predetermined translation ratio between the primary input shaft and the output shaft of the at least one transmission;
- rotating the secondary input shaft at the required rotation speed.
