Systems and methods of providing a configurable powertrain in a vehicle are disclosed. The powertrain is capable of operating in a plurality of powertrain configurations and includes one or more reversible generators, a battery system, a motor/generator (M/G), and one or more drive axles. The generators generate and supply electrical power to the battery system, the M/G, an external power source, or a combination thereof. The battery system selectively supplies electrical power to the generators, the M/G, the external power source, or a combination thereof. The one or more generators also selectively supply cooling to the battery system, a cab of the vehicle, a trailer or external enclosure or structure of the vehicle, or a combination thereof. The powertrain configurations of the vehicle include operating the components of the powertrain in various combinations based on demands of the vehicle and/or external power sources or structures.

A hybrid vehicle includes an engine, an electric machine, a disconnect clutch configured to selectively couple the engine to the electric machine, and a controller. The controller is programmed to, in response to a request to start the engine with the electric machine, command a target pressure to the disconnect clutch that depends on a seal friction derived from a measured line pressure of the disconnect clutch and a rate change of the measured line pressure.

A drive assembly for a work vehicle includes a housing arrangement, a drive shaft rotatable in first and second clock directions, and a two-stage planetary gear set coupled to the drive shaft. The gear set includes, or is coupled to, an output element. First and second clutch arrangements are configured to selectively engage the gear set to effect first and second gear ratios, respectively. A step ratio from the first gear ratio and the second gear ratio is 3:1. At least one first actuator and at least one second actuator are configured to effect movement of the first and second clutch arrangements, respectively, to selectively engage the gear set. The drive shaft and the output element rotate in a same clock direction with the first clutch arrangement engaged with the gear set, and in opposite clock directions with the second clutch arrangement engaged with the gear set.

Methods and systems for a transmission are provided. In one example, the transmission includes an input shaft with a first pair of gears that reside thereon, a first clutch positioned between the first pair of gears and designed to selectively rotationally couple a selected gear in the first pair of gears to the input shaft, and a layshaft with a second pair of gears fixedly coupled thereto. The transmission further includes an output shaft with a third pair of gears that reside thereon and a second clutch positioned between the third pair of gears and designed to selectively rotationally couple a selected gear in the third pair of gears to the output shaft.

Various disclosed embodiments include illustrative systems, vehicles, and methods. In an illustrative embodiment, a system includes a sensor configured to generate route information, and a control unit. The control unit includes a processor in signal communication with the sensor and a memory configured to store computer-executable instructions. The computer-executable instructions are configured to cause the processor to receive the generated route information, generate a wheel signal responsive to the received route information indicating a change in wheel engagement status, and output the wheel signal to a disconnect.

A drive train for a motor vehicle has an electrical machine and a transmission, the drive shaft of which is coupled to the rotor of the electrical machine, wherein the drive train comprises a coupling device which is adapted to couple the drive shaft of the transmission to a power takeoff shaft of the transmission in order to block a rotation of the power takeoff shaft.

A vehicle includes an engine, a torque converter, a transmission, and a control device. The torque converter is coupled to the engine. The transmission is coupled to the torque converter. The control device is configured to control operation of the transmission. The control device includes a controller configured to perform shift hold control to prevent upshift of the transmission based on a lateral acceleration value of the vehicle. The controller is configured to permit the upshift of the transmission by only one gear shift stage in a case where a predetermined condition is met in the shift hold control. The predetermined condition includes a condition that an index value indicating a rotation speed of an output shaft of the torque converter be higher than a first threshold value.

A driving force control system for a hybrid vehicle for reducing a required time to launch the hybrid vehicle after selecting a reverse range while maintaining a driving force. The control system is configured to change an engine start threshold to restrict a startup of the engine upon satisfaction of a restricting condition, in which a low mode is established by a transmission mechanism, and a reverse drive range is selected.

Either a mode in which a vehicle travels with an electric motor or a mode in which the vehicle travels with an internal combustion engine is selected based on information on a fee when the vehicle is caused to travel with the electric motor and information on a fee when the vehicle is caused to travel with the internal combustion engine.

An embodiment power train for a vehicle includes a first input shaft configured to receive rotating forces from a first motor and an engine, a second input shaft configured to receive a rotating force from a second motor, an output shaft disposed in parallel with the first input shaft and the second input shaft, a transmission gear set in which a plurality of gear sets having different gear ratios are engaged with and coupled to the first input shaft and the output shaft, a shifting unit configured to select a gear set of the plurality of gear sets based on a traveling speed of the vehicle, and a motor-side transfer gear set engaged with and coupled to the second input shaft and the output shaft.
