摘要： A control system for a vehicle configured to stabilize a behavior of the vehicle by controlling a split ratio of torque distributed to front wheels and rear wheels. In the vehicle, a split ratio of the torque distributed to the front wheels and to the rear wheels through a transfer is changed by a torque of the motor.
The control system is configured to execute a drive force distribution control to control the torque of the motor to adjust the split ratio to a target ratio, and to execute a turning behavior stabilizing control instead of the drive force distribution control to temporarily increase the torque of the motor when the vehicle is understeering or oversteering.

摘要： An automated differential locking system. The system includes a differential locking system sliding collar that is selectively engageable with a differential case. An actuator disposed within a protruding portion of a housing is in driving engagement with the sliding collar of the differential locking system. In pneumatic communication with the actuator is a differential lock pneumatic solenoid valve that is in electrical communication with pneumatic solenoid valve slave controller. The solenoid valve and the slave controller are J-1939 and/or ISO-11898 compliant. At least a portion of an outer surface of the solenoid valve and the slave controller are integrally connected to at least a portion of an outer surface of the protruding portion of the housing. In response to an occurrence or absence of a predetermined vehicle operating condition, a second controller sends a signal over a vehicle communication bus to engage and/or disengage the collar with the differential case.

摘要： A power transfer unit includes an input shaft extending along an input axis and an intermediate drive shaft extending at least partially through the input shaft along the input axis. The power transfer unit further includes a ring gear assembly having a ring gear and a ring gear shaft coupled to the ring gear. The ring gear shaft at least partially surrounds the input shaft and extends along the input axis. The power transfer unit also includes a collar coupled to the input shaft. The collar surrounds the input shaft and is movable relative to the ring gear shaft along the input axis between an engaged position and a disengaged position. When the collar is in the engaged position, the input shaft is coupled to the ring gear shaft. When the collar is in the disengaged position, the input shaft is decoupled from the ring gear shaft.

摘要： A fork shaft arranged inside a rear-wheel side output shaft is connected to a high-low sleeve of a high-low switching mechanism and a nut member of a screw mechanism that adjusts torque of a front-wheel drive clutch, such that when the nut member moves in an axial direction of the rear-wheel side output shaft, the high-low sleeve moves in the axial direction in conjunction via the fork shaft. Therefore, switching of the high-low switching mechanism and torque adjustment of the front-wheel drive clutch are both able to be executed by the screw mechanism. The fork shaft is arranged inside an axial hole in the rear-wheel side output shaft.
