A vehicle may include a CVT unit or a power source which requires ambient air. An air inlet for an air intake system coupled to the CVT unit or the power source which requires ambient air may be provided in a side of a cargo carrying portion of the vehicle. The vehicle may include a rear radius arm suspension.

The purpose of the invention is to save fuel, which involves a significant reduction of polluting gases for exerting a force that can move a vehicle, by reducing the revolutions of the main motor or engine. For this purpose, the invention relates to a motor is connected to two transmissions associated with the propulsion means or front and rear wheels (11) of the vehicle, such that an output power shaft (4) of the main engine (1) is connected to a hydraulic variable-displacement piston pump (5) that is associated with a hydraulic Circuit (6) with means for selectively recirculating the fluid to a pair of hydraulic motors (8) associated with corresponding differentials (9) of rear and front traction means, such that it is possible to activate either propulsion system, both propulsion systems simultaneously or neither of them.

A method for controlling a vehicle including a main transmission and a hydraulic transmission, in which, in the absence of a setpoint on the brake, and when the hydraulic transmission is activated, a hydraulic pump of the hydraulic transmission is controlled in such a way as to establish a predetermined pressure inside a hydraulic circuit of the hydraulic transmission, and in the event of a setpoint applied to the brake, the hydraulic transmission is then controlled according to an acceleration setpoint applied to the vehicle. If the acceleration setpoint is greater than or equal to an acceleration threshold value, and the speed of travel of the vehicle is less than or equal to a speed threshold value, the hydraulic transmission is controlled in such a way as to apply a tractive force. If the acceleration setpoint is less than the first threshold value, the hydraulic transmission is disengaged.

A drive unit for an electric vehicle includes a first electrical drive assembly which is associated with, and drive-connected to, a motor vehicle front axle, and a second electrical drive assembly which is associated with, and drive-connected to, a motor vehicle rear axle. A center of mass of the first drive assembly lies on a side of the motor vehicle front axle facing away from the motor vehicle rear axle, and a center of mass of the second drive assembly lies on a side of the motor vehicle rear axle facing away from the motor vehicle front axle. Also, a motor vehicle has such a drive unit.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

There is provided an electrically driven vehicle equipped with a first motor configured to output a torque to one of front wheels and rear wheels and with a second motor configured to output a torque to the other of the front wheels and the rear wheels. When a torque of a negative value is required as a required torque that is required for driving, the second motor is controlled to output the torque with a lower limit torque of a positive value as a lower limit, and the first motor is controlled such that the electrically driven vehicle is driven with the required torque.

The vehicle includes a pair of power control units (PCUs) provided corresponding to each of a pair of in-wheel motors. The pair of PCUs include two PCUs having a common structure. The PCU includes a cuboid housing, an MG terminal provided on a first side surface of the cuboid housing, and a battery terminal provided on a second side surface orthogonal to the first side surface. Each of the pair of power control units is arranged such that each of the MG terminals faces a vehicle width direction in which a corresponding in-wheel motor is located and each of the battery terminals faces a same direction in a vehicle front-rear direction.

A four-wheel drive vehicle comprises: main drive wheels; sub-drive wheels; a power transmission path; a first connecting/disconnecting device; and a second connecting/disconnecting device, at least one connecting/disconnecting device of the first and second connecting/disconnecting devices including: a dog clutch; a synchronization mechanism; and an electromagnetic actuator. The four-wheel drive vehicle includes a control device providing the energization control of the electromagnetic coil based on a preliminarily stored current command value to engage the dog clutch of the one connecting/disconnecting device, and the control device learns a characteristic value indicative of an increasing characteristic of the rotation speed of the first rotating member with respect to the current command value and updates the current command value such that an increase rate of the rotation speed of the first rotating member becomes equal to a predetermined rate based on the learned characteristic value.
