An electric drive axle assembly of a vehicle includes an electric motor having an output shaft. At least one of a gear and a planetary gear assembly is coupled to the output shaft of the electric motor. The at least one of the gear and the planetary gear assembly is coupled to a differential mechanism configured to transfer torque to two axle shafts of the vehicle. The electric drive axle assembly configured to produce a plurality of speed ratios between the electric motor and the differential mechanism.

A vehicle power transfer unit assembly includes an input shaft, a shift collar, an outer cam ring, and an inner cam ring. The shift collar is engaged with the input shaft and operable between a first position and a second position. The outer cam ring is disposed around a portion of the shift collar. The outer cam ring includes an inner surface defining a plurality of levels. The inner cam ring is engaged with the shift collar and disposed radially inward from the outer cam ring. The inner cam ring includes a jaw engageable with the plurality of levels. The shift collar is moved from the first position to the second position when the jaw is moved from engagement with one of the plurality of levels to engagement with another of the plurality of levels.

An electrically driven vehicle includes at least one wheel driven by a motor, a vehicle body including a floor panel, a battery pack arranged on the lower side of the floor panel and configured to supply power to the motor, at least one wire harness extending in a front-rear direction of the electrically driven vehicle between the floor panel and the battery pack, and a harness cover extending in the front-rear direction of the electrically driven vehicle along the at least one wire harness and interposed between the at least one wire harness and the battery pack.

Through-the-road (TTR) hybrid designs using control strategies such as an equivalent consumption minimization strategy (ECMS) or an adaptive ECMS are implemented at the supplemental torque delivering electrically-powered drive axle (or axles) in a manner that follows operational parameters or computationally estimates states of the primary drivetrain and/or fuel-fed engine, but does not itself participate in control of the fuel-fed engine or primary drivetrain. BSFC type data particular to the paired-with fuel-fed engine allows an ECMS implementation (or other similar control strategy) to adapt to efficiency curves for the particular fuel-fed engine and to improve overall efficiencies of the TTR hybrid configuration.
