Systems and methods are described for electrical power control of a hybrid vehicle. A change in an electrical load of an ancillary component of the vehicle is determined. In response to determining the change in the electrical load of the ancillary component, an electrical load of an electrically heated catalyst of the vehicle is adjusted.

A hybrid transmission device (3) includes at least one drive device (EM2) and a transmission (4) with a first transmission input shaft (12) and a second transmission input shaft (14) mounted on the first transmission input shaft (12). The at least one drive device (EM2) is arranged axially parallel and is connected to a gear-step gearwheel (16) arranged on the second transmission input shaft (14).

A transmission unit for a hybrid motor vehicle, includes an input shaft that can be connected to an internal combustion engine, a planetary gearing, which can be coupled to the input shaft, the planetary gearing having a first planetary wheel set and a second planetary wheel set, a first electric machine the rotor of which is rotationally fixedly coupled to the input shaft, a second electric machine which is coupled with a component part of the planetary gearing, and no more than four switching devices, each of which forms a brake or a clutch, and each can be moved between an activated position and a deactivated position. The switching devices are used for switching various transmission ratios acting between the input shaft and an output shaft and/or between the second electric machine and the output shaft. The no more than four switching devices are configured to implement four different transmission ratios in a drive state of the internal combustion engine, and two different transmission ratios in a drive state of the second electric machine, thereby implementing a serial operation as a result of their activated and deactivated positions. The invention disclosure also relates to a motor vehicle comprising said transmission unit.

A hybrid module for a hybrid vehicle is disclosed. The hybrid module has two clutches located radially inward of an electric motor, and in their own respective fluid chamber. Fluid from one chamber can cool one of the clutches. Then the fluid can travel axially to the other chamber to cool the other clutch. The hybrid module can include a wall assembly between the two clutches, separating the fluid chambers. After the fluid cools both clutches, the fluid is directed to the wall assembly, and passes through two walls, radially outwardly, to spray onto the electric motor to cool the motor.
