A method of operating an engine of a work machine, via a controller, includes detecting a request for a transmission shift of a transmission of the work machine from a neutral gear to a desired starting gear; determining a current transmission output speed of the transmission; determining a desired transmission output speed of the transmission corresponding to the desired starting gear; determining a desired minimum speed of the engine based on a difference between the current transmission output speed and the desired transmission output speed; and causing, based on the request for the transmission shift, the engine to operate at or above the desired minimum speed prior to a completion of the transmission shift from the neutral gear to the desired starting gear.

Methods and systems for an electric drive unit. The electric drive unit includes, in one example, a stator assembly with a first set of stator windings and a second set of stator windings, a first set of rotors in which each rotor is configured to electromagnetically interact with the first set of stator windings and rotationally couple to a distinct gear in a first summation gear set, a second set of rotors in which each rotor is configured to electromagnetically interact with the second set of stator windings and rotationally couple to a distinct gear in a second summation gear set. The electric drive unit further includes a disconnect clutch configured to rotationally disconnect a first rotor in the first set of rotors from the first summation gear set.

A battery electric vehicle transmission with a disengaging function includes an input shaft, an output shaft, and an intermediate shaft. An input shaft gear is arranged around the input shaft and the input shaft is engaged with an intermediate gear on the intermediate shaft via the input shaft gear, the intermediate gear is engaged with an output gear on the output shaft, the input shaft is connected with an auxiliary drive motor, and the output shaft is connected with vehicle wheels. The transmission further includes a synchronizer, and an engagement sleeve of the synchronizer is driven by a shift mechanism to switch between an engagement position and a disengagement position of the input shaft gear. The shift mechanism includes a BLDC motor, a shift gear and a shift fork, the shift gear is driven by the BLDC motor to drive the shift fork to move linearly.

A motor vehicle includes an electric drive machine and a coupling mechanism for switching between a coupling position, in which the electric drive machine is coupled to a drive wheel of the motor vehicle, and a decoupling position in which the electric drive machine is decoupled from the drive wheel. The motor vehicle further includes a parking lock device which has a parking lock element movable between a parking lock position, in which the parking lock element blocks a rotation of the drive wheel, and an unlocking position in which the parking lock element releases rotation of the drive wheel. The motor vehicle also includes an actuation device to actuate a clutch of the coupling mechanism, which clutch has a switching element for switching between the coupling position and the decoupling position, and moving the parking lock element between the parking lock position and the unlocking position.
