A drive device and method for a motor vehicle, provided with a combustion engine machine, with a first electric machine and with a second electric machine, wherein a drive shaft of the combustion engine machine can be coupled by a first clutch to a drive shaft of the first electric machine, which is connected via a transmission drive to a drive shaft of the drive device. At the same time, the gear device is permanently coupled to the drive shaft of the first electric machine and provided with a planetary gear that can be coupled by a second clutch to the drive shaft of an internal combustion engine, wherein the second electric machine is permanently coupled to the drive shaft.

A hybrid drive device has an internal combustion engine, a clutch transmission which has at least one free partial transmission and a partial transmission connected to an electric machine with in each case a clutch, and at least one electric machine. In order to start the internal combustion engine, pulse energy is provided from an inertia of the clutch associated with the free partial transmission and/or a rotation in the free partial transmission.

The invention relates to a method, performed by a control device, for driving at least one power consumer connected to a powertrain of a vehicle. The at least one propulsion unit comprises a first electrical machine and a second electrical machine, wherein the first electrical machine is connected to a first main shaft and the second electrical machine is connected to a second main shaft. A connection shaft is connected to the first electrical machine; and the at least one power consumer comprises a first power consumer connected to the first main shaft and/or a second power consumer connected to the connection shaft. The method comprising: controlling the powertrain to provide uninterrupted propelling torque on the first main shaft and/or on the connection shaft during a stand still condition of the output shaft of the gearbox and/or during a transition from a stand still condition to a rotational condition of the output shaft of the gearbox, and/or during gear shifting from one gear to another gear in the gearbox. The invention also relates to a vehicle comprising a powertrain, a computer program and a computer-readable medium.

A vehicle control apparatus for controlling a vehicle through a control program using at least one parameter. The at least one parameter is corrected by respective at least one correction value that is obtained after start of execution of a learning operation. The vehicle control apparatus includes: a learning-data storage portion configured to store, as learning data, the at least one correction value obtained after the start of the execution of the learning operation; and a learning-data rewrite portion configured, when the control program is updated, to execute a rewriting operation for rewriting the at least one correction value as the learning data from a pre-update correction value to a post-update correction value, such that the post-update correction value has the same sign as the pre-update correction value, and an absolute value of the post-update correction value is smaller than an absolute value of the pre-update correction value.

Methods and systems for tuning vehicle drivability are provided. The vehicle system includes, in one example, a vehicle control unit (VCU) that is designed to electronically communicate with a human machine interface (HMI). In the system, the VCU is designed to, in reaction to receiving an acceleration or deceleration request from the HMI, send a virtual acceleration or deceleration command to a transmission control unit (TCU), where the virtual acceleration or deceleration command correlates to the acceleration or deceleration request and the correlation is user adjustable via a user interface (UI) of the VCU.
