  • Patent number: 11364787
    Abstract: A hybrid drive train includes a first electric motor, a nested power splitting planetary gear set having a first carrier element and a second carrier element, an inner sun gear coupled with the first electric motor and an outer sun gear coupled with an output shaft. A first selectable one-way clutch controls the first and the second carrier element, and switches between operation as a one way clutch and operation as a brake. A second selectable one-way clutch controls a ring gear of the nested planetary gear set, and switches between operation as a one way clutch and operation as a brake. The extra outer planetary gear set improves towing capacity at higher speeds without substantially increasing the axial length of the power split device.

  • Patent number: 11180016
    Abstract: The present invention provides a power system for a hybrid vehicle, relating to the field of hybrid vehicles. The power system mainly includes an engine, a first motor, a second motor, a first planetary gear mechanism, a second planetary gear mechanism, a first input shaft, a first clutch, a brake, and a second clutch. Since the second motor is connected to the first input shaft through the second planetary gear mechanism, the planetary gear mechanism can reduce the speed of the second motor and increase the torque to effectively reduce the size of the second motor or improve the acceleration performance of the vehicle. Since the first clutch between the first input shaft and the engine is disengaged when driven by the second motor, the drag resistance of the engine is reduced, and the fuel economy of the vehicle is improved.

  • Patent number: 11148654
    Abstract: A transmission system constructed in accordance to one example of the present disclosure includes an aftertreatment system and a controller. The transmission system is selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle. The aftertreatment system reduces emissions in an exhaust of the internal combustion engine. The controller operates in an aftertreatment heat-up mode such that the aftertreatment system is heated up to an elevated temperature and emissions are thereby reduced based on the elevated temperature. The controller operates in the aftertreatment heat-up mode when the internal combustion engine is operating at or below a brake mean effective pressure between three and four bar. The aftertreatment heat-up mode comprises increasing load on the internal combustion engine.
