A control apparatus of an all-wheel drive vehicle includes a vehicle speed detector, a first clutch, a second clutch, and a clutch controller. The vehicle speed detector detects a speed of the all-wheel drive vehicle. The first clutch is provided between a parking mechanism and a drive force source of the all-wheel drive vehicle, and adjusts first drive force to be transmitted from the drive force source to an output shaft of an automatic transmission of the all-wheel drive vehicle. The second clutch is provided between the parking mechanism and a drive wheel of the all-wheel drive vehicle, and adjusts second drive force to be transmitted from the output shaft to the drive wheel. The clutch controller controls engagement force of the first and second clutches, and disengages the first and second clutches when the speed of the all-wheel drive vehicle is equal to or less than a predetermined speed.

An ATV is shown having a radiator that is coupled to the frame forward of and a hood is rotatably coupled to the frame and having an open position providing access to the radiator and a closed position enclosing the radiator.

A vehicle includes three pairs of wheels, each pair being spaced apart in a right-left direction, three differential gears, respectively corresponding to the three pairs of wheels, and an engine that generates a rotation to be transmitted to the three pairs of wheels through the three differential gears. The engine is located rearward of a front differential gear that is any one of the three differential gears and is fixed to the front differential gear.

A vehicle is operable in three modes of operation. The vehicle includes a first electromagnetic device, a second electromagnetic device electrically coupled to the first electromagnetic device, and an engine coupled to the first electromagnetic device and configured to drive the first electromagnetic device to provide electrical energy. In each of the three modes of operation, whenever the engine drives the first electromagnetic device to provide the electrical energy, the first electromagnetic device operates without providing the electrical energy to an energy storage device.

A power-split transmission which is designed to be operated with either first or second deceleration logics. The second deceleration logic has a higher deceleration dynamic than the first deceleration logic, and is designed to disengage an engaged range clutch immediately so as to reduce the transmission ratio by way of a hydrostatic unit with a maximum dynamic. A method of operating the transmission includes: monitoring various vehicle parameters while the vehicle is operated with the first deceleration logic; detecting that at least one set limit value has been exceeded while the vehicle operated with the first deceleration logic; activating the second deceleration logic, to immediately disengage an engaged range clutch; reducing a transmission ratio to a maximum using the hydrostatic unit, the hydrostatic unit being displaced with a maximum dynamic; and engaging the range clutch and activating the first deceleration logic.

A driveline for vehicles provided with a dual function CVT is described herein. The driveline includes a dual function CVT that can be used both to power the ground engaging wheels of the vehicle and to power an accessory drive thereof.

A work vehicle includes a propelling device, which consists of a pair of right and left front wheels and a pair of right and left rear wheels, an engine configured to drive one of the pair of front wheels and the pair of rear wheels, an electric motor configured to drive the other of the pair of front wheels and the pair of rear wheels, a battery configured to supply electric power to the electric motor, and a controller configured to control the electric motor. The controller performs regeneration control at constant current value to charge the battery with regenerative power of the electric motor at a constant current value regardless of rotation speed of the electric motor.

A continuously variable transmission includes two planetary gear sets having two planetary outputs and a planetary output shaft with a first drive gear. A variator drives a ring gear of the second planetary gear set, and a transmission input shaft is driven by the engine, which also drives the variator and the planetary input. Forward and reverse output systems are connected to the planetary output shaft and a transmission output shaft. A first clutch connects the first planetary output to the first drive gear, and a second clutch connects the second planetary output to the first drive gear. A third clutch connects the second planetary output to a second drive gear of the planetary output shaft, with the second drive gear being connected to the forward output system.

A method of operating a first electric machine and a second electric machine in a vehicle drive includes operating the vehicle drive in a first operating mode by operating the first electric machine to regulate electrical power at a bus to maintain a first voltage on the bus and operating the second electric machine to consume electrical power from the bus. The method includes operating the vehicle drive in a second operating mode by operating the first electric machine to consume electrical power from the bus and operating the second electric machine to regulate electrical power at the bus to maintain a second voltage on the bus. A sum of the electrical power regulated by the first electric machine, the electrical power losses, and the electrical power consumed by the second electric machine is zero in the first operating mode and in the second operating mode.

A motor vehicle includes a motor and a transmission including a drive shaft driven by the motor and connecting the motor to the transmission, a first output shaft extending along the vehicle longitudinal axis in the one direction, which first output shaft is connected to a wheel axle by a first differential, and a second output shaft extending along the vehicle longitudinal axis in the opposite direction, which second output shaft is connected to a second wheel axle by a second differential, characterized in that the drive shaft is disposed in the longitudinal axis of the motor vehicle and the first and the second output shaft are disposed on opposing sides relative to the longitudinal axis of the motor vehicle with identical spacing with respect to the longitudinal axis of the motor vehicle.
