An implement drive system is provided for an implement towed by a prime mover vehicle in a work vehicle train. The system includes an axle arrangement and an auxiliary power unit. The auxiliary power unit includes an electric motor; a planetary gear set receiving rotational input from the electric motor and providing a rotational output with a decreased rotational speed and an increased torque relative to the rotational input; and a disconnect device having an output configured to be coupled to the axle arrangement. The disconnect device is movable to a first position in which the disconnect device transfers the rotational output from the planetary gear set to the axle arrangement such the rotational input drives the wheels of the implement. The disconnect device is movable to a second position in which the disconnect device decouples the axle arrangement from the rotational input of the electric motor.

The vehicle system can include: a set of vehicle couplings (e.g., a tractor interface, a trailer interface, etc.); a chassis, a battery pack, an electric powertrain, a sensor suite, and a controller. The modular vehicle system can optionally include landing gear, a suspension, and any other suitable set of components. The vehicle system functions to structurally support and/or tow a trailersuch as a Class 8 semi-trailerand/or to augment/supplement a tractor propulsive capability (e.g., via a diesel/combustion engine) with a supplementary electric drive axle(s).

A method for controlling the driving of at least one drive axle on a trailer of a traction vehicle-trailer combination includes determining a target drive power for the drive axle of the trailer as a function of a distribution of contact forces on the trailer or on the traction vehicle, or as a function of a traction drive power for the traction vehicle. The method further includes providing drive control signals for controlling an electrical drive for the drive axle of the trailer. The drive control signals are derived from the determined target drive power.
