A continuously variable power-split transmission with at least four driving ranges, within which the gear ratio of the power-split transmission can be continuously varied by a variator. A first planetary gearset with a plurality of shafts can be connected via shifting elements with another planetary gearset that also has a plurality of shafts and can be connected with a transmission output shaft. The first planetary gearset comprises four shafts and can be connected, via a first shaft, with a transmission input shaft and a first shaft of the variator.

A drive train unit for a vehicle includes a housing, an input shaft rotatably mounted in the housing and arranged for rotationally fixed attachment to an output of a transmission, a first clutch operable between a rotor of an electric machine and the input shaft, and a coolant delivery device integrated in the housing. The coolant delivery device is arranged to generate a coolant circuit from the input shaft outwardly in a radial direction when the input shaft is rotated. The coolant delivery device has a discharge element for deflecting coolant flowing in a circumferential direction into a channel inwardly in the radial direction. The drive train unit may include the electric machine with the rotor. The drive train may have an output shaft and a second clutch operable between the input shaft and the output shaft.

A drive motor includes a torque sensor on an outer circumference of a shaft. The drive motor includes a rotor, a rotor shaft arranged inside the rotor, and an output shaft that is joined to the rotor shaft by a joint having a loose element. In the drive motor, the output shaft outputs rotational force of the rotor shaft to the output side. The torque sensor is arranged on an upstream side of the joint in a range not overlapping with the joint.

A hybrid electric powertrain for a vehicle includes an engine, electric machine, torque converter having a pump, turbine, and torque converter clutch (“TCC”) configured, when applied, to lock the pump to the turbine, a one-way engine disconnect clutch connected to the turbine, a transmission, and a controller. A transmission input shaft directly couples to the electric machine, and is selectively coupled to the engine via the disconnect clutch. An output shaft is connectable to road wheels of the vehicle. The controller, in response to an engine-off request, determines turbine and pump speeds of the turbine and pump, respectively, registers that the engine is in an engine-off state when the pump speed is less than the turbine speed, and executes an electric vehicle (“EV”) mode shift using machine torque from the electric machine when the pump speed is zero during the engine-off state.
