Definitions
- the invention relates to a drive train, by means of which a torque provided, for example, by an internal combustion engine can be converted in order to set a desired torque and / or a desired rotational speed at the output of the drive train.
- a typical powertrain for a motor vehicle includes an internal combustion engine that provides torque that may be introduced into a torque converter power transmission.
- the power-split or non-power-split power transmission can be configured as a planetary gear in order to vary the torque and speed continuously in a defined range.
- the powertrain according to the invention for a motor vehicle has a power transmission for torque conversion and a first drive motor, in particular an internal combustion engine, which can be coupled to the power transmission.
- a detachable with the power transmission second drive motor, in particular internal combustion engine is provided, wherein both the first drive motor and the second drive motor are power-split or not power split via a common variable transmission with the power transmission.
- CONFIRMATION COPY Operate internal combustion engine, while the other internal combustion engine is not coupled to the power transmission and / or off.
- This makes it possible, instead of a single engine with a high performance to provide two or more engines with low power, so that at partial load, if only one internal combustion engine is operated, the operated Brennkraftma machine can be operated in the vicinity of the optimum operating point.
- a plurality of internal combustion engines can be operated simultaneously, whereby it is possible to operate both the first internal combustion engine and the second internal combustion engine in the vicinity of the optimum operating point.
- This makes it possible to operate at different power ranges of the drive train, the internal combustion engine in the vicinity of the optimum operating point, whereby the fuel consumption in different power ranges can be kept particularly low.

- the first drive motor can be uncoupled via a first motor coupling and / or the second drive motor can be uncoupled via a second motor coupling.
- the associated drive motor can be separated from the drive train in such a way that no power flow between the uncoupled drive motor and the rest of the drive train can take place.
- a decoupled drive motor which is not in operation, can not slow down the drive train, so that unnecessary power is lost. kungsgradmule are avoided.
- a maximum of one variator is provided.
- a summing gear to split and / or merge the output from the first drive motor and the second drive motor power is not required. Instead, the power delivered by the drive motors in the variator can be completely or partially merged and introduced via a defined unbranched flow of power in the power transmission. This for a compact and space-saving design of the powertrain.

- the second drive motor can be coupled or disconnected with the aid of the control device in order to be able to set the most fuel-efficient operating mode possible for different power ranges.
- the control device is optionally connected via a separate variator with the variator, so that for example via a feed-forward control, the variator can be prepared in time for a sudden uncoupling and / or coupling of the second drive motor. Undesirable effects of a sudden load change when coupling and / or uncoupling the second drive motor on the ride comfort can be alleviated.
- the second drive motor can be connected to the variational gear via the first drive motor, or the first drive motor and the second drive motor can each be connected separately to the variational gear arranged between the first drive motor and the second drive motor.
- the first drive motor and the second drive motor may be connected in series and coupled to the variator from one side only via the first drive motor.
- the second drive motor can thereby be easily started by the first drive motor when coupling the first drive motor.
- a torque for starting a designed as a combustion engine second drive motor can thereby be provided without a plurality of intermediate elements, so that unnecessary efficiency losses are avoided when starting the second drive motor.
- several second drive motors can be connected in series one behind the other.
- the variator can be arranged between the first drive motor and the second drive motor, resulting in a substantially T-shaped arrangement of the drive motors and the variator, depending on the available Installation space for the drive train may be advantageous.
