A traction control device and method for a four-wheel drive electric vehicle are disclosed. When the drive wheels of an electric vehicle spin, a drive force of the electric vehicle is controlled so as to restrain the spinning of the drive wheels and to secure the starting performance and acceleration performance of the electric vehicle.

A transmission subassembly for a working vehicle includes an engageable front wheel drive, a transmission housing, a clutch module, and a hydraulic module. The hydraulic module is received between the clutch module and the transmission housing.

A vehicle with one-pedal driving mode includes a first axle having a first electric machine configured to power first wheels and a second axle having a second electric machine configured to power second wheels. A controller is programmed to, in response to a request for one-pedal driving mode, map pedal positions of the accelerator pedal to speeds of the first and second wheels such that each of the pedal positions corresponds to a driver-demanded speed of the first and second wheels, and control one or more of the electric machine so that the vehicle is propelled according to the driver-demanded speed.

Disclosed is a method of controlling a hybrid electric vehicle having a transmission, an engine, and first and second drive motors. The method includes: performing charging through the first drive motor using the power of the engine by engaging an engine clutch disposed between the engine and the first drive motor while a vehicle is stopped with the gear stage shifted to the parking (P) range; turning off the engine and controlling the clutch of the transmission to enter an open state when the gear stage is shifted to the driving (D) range; and commencing movement of the vehicle using the second drive motor alone or using at least one of the first drive motor or the engine together with the second drive motor based on at least one of requested torque, available torque of the second drive motor, or the speed of the first drive motor.

A vehicle includes a rear axle having wheels, friction brakes associated with the wheels, and a driver-actuatable input. A vehicle controller is programmed to, in response to the vehicle being in drift mode and the driver-actuatable input being actuated: command zero torque to the wheels, regardless of a driver-demanded torque, for a duration of time; command engagement of the friction brakes responsive to the duration of time ending; and command torque to the wheels responsive to a speed of the wheels being less than a threshold.

Disclosed is a motor system control apparatus for vehicles including a communication unit communicatively connected to a plurality of motor systems and a controller configured to, upon recognizing that one of the motor systems is broken, control the motor system such that a battery is charged using counter-electromotive force of a motor, wherein the controller confirms whether, upon recognizing breakdown of the motor system, the broken motor system is capable of generating counter-electromotive force, decides whether to generate the counter-electromotive force based on a state of charge (SOC) and a traveling state of a vehicle upon confirming that the broken motor system is capable of generating the counter-electromotive force, controls the broken motor system such that the counter-electromotive force is generated upon deciding to generate the counter-electromotive force, and charges the battery with electrical energy generated by the counter-electromotive force.

A zero emissions electrically powered haul truck is disclosed. The haul truck has a 40 metric ton hauling capacity and a form factor that allows the truck to travel through underground mines. The truck also includes a primary battery assembly that is externally mounted along the front and sides of the truck.

Provided is a vehicle power device including: an inner ring as a fixed ring, an outer ring as a rotary ring which is an outer ring rotation, and a bracket a knuckle for fixing an inboard side end portion of the inner ring removably with the electric motor disposed. The electric motor is of an outer rotor motor type, and the bracket includes a bracket base portion and a bracket cylindrical portion, the bracket base portion for being attached to the knuckle and fixed to the inner ring, the bracket cylindrical portion which extends from the bracket base portion toward an outboard side is located on an outer periphery of the outer ring via a radial gap and is provided with a stator disposed on an outer peripheral surface. The rotor of the electric motor is removably attached to the wheel mounting flange via a rotor casing.

Provided is a vehicle power device (1) including: a wheel bearing (2); and a driving motor (3) that can rotationally drive an outer ring (4) as a rotary ring. The vehicle power device further includes a bracket (24) attached to a knuckle (8) of a vehicle. The bracket (24) includes a bracket base portion (24a) and a bracket cylindrical portion (24b), the bracket base portion interposed between the knuckle (8) and an inner ring (5) wherein the inner ring (5) is removably fixed, the bracket cylindrical portion (24b) extending from the bracket base portion (24a) toward an outboard side. The driving motor (3) includes a stator (18) removably attached to an inner periphery of the bracket cylindrical portion (24b) and a rotor (19) attached to the outer ring (4) on an inner periphery of the stator (18).
