摘要： Systems and methods for a multi-speed electric axle. The multi-speed electric axle includes an electric motor that is rotationally coupled to an input shaft. The multi-speed electric axle also includes a planetary gearset connected to the input shaft via an input gear reduction, a lower-speed clutch that selectively grounds a ring gear in the planetary gearset to a housing, and a higher-speed clutch that selectively connects a sun gear to a carrier.

摘要： A system for a driveline is provided. In one example a driveline may include a first and a second input shaft gear disposed on an input shaft. In one example, the first input shaft gear may selectively drivingly engage with the input shaft via a first clutch and the second input shaft gear may selectively drivingly engage with the input shaft via a second clutch. In another example, a first and a second counter shaft gear may be disposed on a countershaft and drivingly engage with the countershaft, wherein the first input shaft gear drivingly engages with the first countershaft gear and the second input shaft gear is drivingly engages with the second countershaft gear via an idler gear.

摘要： Methods and systems are provided for a vehicle. In one example, a method for the vehicle includes adjusting an output torque of an electric machine to produce a desired vehicle speed and direction of propulsion while operating an auxiliary load powered via the transmission. The output torque may be adjusted while disengaging clutches of a transmission or a service brake to mechanically unlock an output shaft of the transmission. The first electric machine may be operated in a speed control to learn an amount to torque to hold the vehicle speed at zero and the amount of learned torque may be superimposed with an amount of requested torque upon vehicle launch.

摘要： A dual-motor transmission therefor, comprising a first and a second electric traction motor, a first gear arrangement, a second gear arrangement, and a summation box. The first gear arrangement includes a shaft and at least a first gear and a second gear, wherein each of the first and the second gears can be selectively engaged and disengaged with the shaft via a clutch, and the first gear arrangement supplies a first torque from the first motor to the summation box. The second gear arrangement includes a shaft and at least a first gear, wherein the first gear can be engaged and disengaged with the shaft via a clutch, and the second gear arrangement supplies a second torque from the second motor to the summation box, and the summation box is configured to combine the first and second torques and to output a combined output torque.

摘要： Methods and systems are provided for a hybrid transmission. In one example, a method for a hybrid transmission, comprising, adjusting voltage on an inverter of an electric motor prior to disconnecting or connecting a battery contact in response to a transition between a first mode and a second mode. In the first mode, a battery and at least the electric motor are used to power rotation of a transmission output shaft. In the second mode, an engine and at least the electric motor are used to power rotation of the transmission output shaft. In one example, the adjusting is initiated in response to a request to transition between the first mode and the second mode. In one example, the method includes controlling current to the battery to within a non-zero threshold of zero in response to the request to transition the first mode to the second mode.
