  • Patent number: 10166865
    Abstract: A method for controlling a vehicle driveline uses sensors to estimate a need for powering secondary wheels for each of a plurality of conditions. The estimates are scaled and the scaled estimates summed. Only primary wheels are powered when the summed estimates are less than a reference value. Both the primary and secondary wheels are powered when the summed estimates exceed the reference value.

  • Patent number: 9764739
    Abstract: A transfer case and transmission are designed to permit the transmission hydraulic control system to control a range selection coupler and a torque on demand clutch in the transfer case. Two pressure circuits are transmitted from the transmission to the transfer case: a high range circuit and a low range circuit. The low range circuit is pressurized to engage low range while the range circuit is pressurized to engage high range. The torque on demand clutch is controlled by whichever of these circuits has the higher pressure. Lubrication is provided to a front section of the transfer case via the transmission output shaft, with the fluid returning to the transmission sump through a drainback passageway. The rear portion of the transfer case has a segregated sump. A control strategy is employed to partially fill front section of the transfer case with fluid in preparation for vehicle towing.

  • Patent number: 9573463
    Abstract: A front wheel drive transmission is adapted for all-wheel drive by the addition of a selectively engageable power take-off shaft. When a disconnect clutch is engaged, power may be transferred to rear wheels via a power take-off unit and a rear drive unit to improve vehicle mobility. When the disconnect clutch is disengaged, various components of the all-wheel drive system do not rotate, reducing parasitic losses and improving fuel economy. To provide packaging space for the disconnect clutch, the differential is moved to the left (driver side) of the driven transfer gear. A planetary differential, such as a double pinion planetary differential, is suitable for this location.

  • Publication number: 20160339779
    Abstract: A vehicle includes a power source configured to provide drive torque, a front axle, a rear axle, and a transfer case configured to distribute drive torque from the power source between the front axle and the rear axle. The vehicle additionally includes a clutch arranged between the front axle and the transfer case. The clutch has a disengaged state and an engaged state drivingly coupling the transfer case and the front axle. The vehicle also includes a regenerative braking system configured to, in response to a braking request, provide regenerative braking torque to the rear axle. The vehicle further includes a controller. The controller is configured to, in response to a braking request and the clutch being in the disengaged state, control the clutch to shift into the engaged state to couple the regenerative braking system to the front axle and provide regenerative braking torque to the front axle.

  • Patent number: 9016150
    Abstract: A vehicle powertrain includes a transaxle configured to drive front wheels and a power take-off unit configured to drive rear wheels through a driveshaft. The power take-off unit includes a disconnect clutch such that the power flow path to the rear wheels can be disconnected to reduce fuel consumption and reconnected when needed for traction enhancement. Although the disconnect clutch is physically located within the power take-off unit, it is actuated by fluid from the transaxle valve body. The disconnect clutch actuator includes a piston that slides within a chamber in a housing and a solenoid controlled valve that fluidly connects the chamber either to a pressure source or to the transaxle sump.

  • Patent number: 8777805
    Abstract: A system and a method for controlling a hybrid vehicle powertrain during a change from a two-wheel drive mode to a four-wheel drive mode is provided. In response to a request to couple the second pair of wheels to the powertrain, a driveline controller commands an increased torque from the electric motor to be applied to the first pair of wheels The increased torque from the electric motor is based on an AWD engagement torque of the second pair of wheels to counteract an engagement torque of a second pair of drive wheels before changing from the two-wheel drive mode to the four-wheel drive mode.
