The invention comprises a transaxle having an electric motor that is controlled by a vehicle user and that drives at least one output axle. The transaxle includes a power generating device that powers the electric motor and a reduction gear train engaged to and driven by the electric motor. The transaxle includes a common housing in which the power generator, the electric motor, and the reduction gear system are each disposed. In dual-axle systems, the transaxle also includes a differential engaged to and driven by the reduction gear system to power a pair of oppositely extending output axles. The differential is also disposed within the common housing.

An example vehicle comprises: (i) a source of direct current power, (ii) at least one electronically-commutated electric motor configured to drive a wheel of the vehicle, and (iii) a voltage bus connecting the source of direct current power with the electronically-commutated electric motor.

Embodiments of an intelligent hybrid powertrain system include an engine, a controller architecture, and an electric drive subsystem having a battery supply and a motor/generator. The controller architecture is configured to: (i) monitor a current state of charge (SoC) of the battery supply when the combine harvester engages in a combine harvest cycle having a tank fill phase and a tank unload phase; (ii) during the tank fill phase, operate the motor/generator to supplement the engine power output and regulate a rate of battery discharge to prevent the current SoC of the battery supply from decreasing below a lower predetermined SoC threshold prior to completion of the tank fill phase; and (iii) during the tank unload phase, operate the motor/generator to charge the battery supply until the current SoC of the battery supply is equal to or greater than a first upper predetermined SoC threshold.

A ZTR mower includes a pair of rear drive wheels, a mowing deck including multiple cutting blades, an electric storage battery, a pair of electric wheel motors each configured to rotate one of the rear drive wheels, multiple electric blade motors each configured to rotate one of the multiple cutting blades, and a master controller in communication with each of the pair of wheel motors and the multiple blade motors. The master controller is configured to control a rotational speed of each of the pair of wheel motors and the multiple blade motors. The master controller is configured to send voltage pulses to the multiple blade motors.

An autonomous work vehicle including a positioning information obtaining unit including a GNSS receiver acquiring a position of the autonomous work vehicle, a driving unit including a motor, a memory storing position coordinates used to establish an entry avoidance zone, and a control unit including a processor. The control unit is configured to function as a zone entry judgement unit determining whether the autonomous work vehicle has approached the entry avoidance zone, and a zone entry validation unit determining whether the determination by the zone entry judgement unit that the autonomous work vehicle has approached the entry avoidance zone is valid. When the zone entry judgement unit determines that the autonomous work vehicle has approached the entry avoidance zone, and the zone entry validation unit determines that the determination by the zone entry judgement unit is valid, the control unit controls the autonomous work vehicle to perform an avoidance maneuver.

An electric power equipment includes a drive source, a clutch provided in a power transmission path between the drive source and the travel unit and a controller for controlling an operation of the drive source. Wherein the controller is configured that in a process of increasing a speed in accordance with a rotational speed command value, when a rotational speed of the drive source reaches the clutch connection rotational speed, the increasing of the speed in accordance with the rotational speed command value is interrupted, and when the rotational speed of the drive source reaches a predetermined rotational speed, the increasing of the speed in accordance with the rotational speed command value is performed.
