A power train supporting structure for a vehicle is provided with: a power train including a transversely disposed engine, a transmission, and a transfer; and a rear mount bracket which connects a rear portion of the power train and a suspension cross member. A front portion of the rear mount bracket is connected to the transfer at a position which is below a drive shaft, and is in a vehicle up-down directional area that is an overlapping of the transmission and the transfer in view of the vehicle width direction.

A work vehicle comprises: a vehicle frame; a driving portion in which a driver seat is provided; an electric motor for driving the vehicle to travel; and a battery for supplying electric power to the electric motor, the battery including a plurality of battery modules accommodated in a single battery pack. Each of the battery modules is formed as a rectangular box whose longitudinal length is different from its lateral length in a planar view, and the battery modules are arranged adjacent to each other with a short side of one of the battery modules opposing a long side of the other of the battery modules. The battery pack is also formed to conform to the contour of the aggregate of the battery modules.

A drive system with one or more electrically driven axles, a transmission subsystem, which is drivingly coupled to a drive gearbox of each of the electrically driven axles, first and second motors, which are each drivingly coupled to the transmission subsystem and have different motor characteristics, and a controller. The drive gearbox of each axle transmits rotary power to an associated set of vehicle wheels. The controller controls the first and second motors responsive to at least a torque request. Over a significant portion of the operating range of the drive system, the controller is configured to vary the respective magnitudes of the rotary power provided by the first and second motors to satisfy the torque request in a manner that maximizes a combined efficiency of the motors in a predetermined manner.

A movable structure driving unit is a movable structure driving unit used for a movable structure, including: an electric motor that is electrically connected to a power supply and that drives a front wheel; a rear-side motive power source that drives a rear wheel; a jump detector that detects a jump of the front wheel from ground; and a motor controller that controls driving of the electric motor. The motor controller stops supply of a driving current from the power supply to the electric motor when the jump of the front wheel from the ground is detected in a state in which driving of the front wheel and the rear wheel is instructed.

A multi-purpose utility vehicle for construction and snow-removing work includes: a cargo box seated on a loading frame in the rear part of the vehicle; a continuously variable transmission combination mounted in a mounting space partitioned by a midship frame in the middle of a vehicle body; an engine assembly mounted in an engine room partitioned by a loading frame and base frames of the vehicle body at the back of the midship frame; a front wheel propeller shaft and a rear wheel propeller shaft which respectively transfer driving power outputted from the continuously variable transmission combination to a front axle combination of a front end of the vehicle body and a rear axle combination of a rear end of the vehicle body; and a PTO electromotive system extending from the front of the continuously variable transmission combination to the front of the vehicle body.

A vehicle drive system for an electric vehicle having in-hub motors configured to be independently controlled from the main traction motors. The configuration allows for robust control of the vehicle dynamics and behavior by allowing an improved powertrain control. The system also allows the vehicle to achieve better efficiencies.

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.

A torque upper limit value changing section increases an upper limit value of a torque instruction value in a powering range in case a rotational speed reduction degree is greater than a reference value and decreases the upper limit value of the torque instruction value in the powering range in case the rotational speed reduction degree is smaller than the reference value.
