  • Patent number: 7331896
    Abstract: A drivetrain of an all-wheel drive motor vehicle provided for selective actuation and control of the torque distribution between first and second drive axle assemblies to match various vehicle operating conditions. The drivetrain comprises a power drive unit including a prime mover, the first drive axle assembly driven by the power drive unit to drive a first set of wheels, the second drive axle assembly driven by the power drive unit to drive a second set of wheels, a first clutch unit provided to disconnect the first drive axle assembly from the power drive unit, and a second clutch unit provided to disconnect the second drive axle assembly from the power drive unit.

  • Patent number: 7134980
    Abstract: An integrated control system for a motor vehicle including at least one drive axle having left and right axle shafts each provided with a wheel mounted thereon. The integrated control system comprises a vehicle torque control system, a vehicle body roll control system, and a common source of a fluid pressure provided to operate both the vehicle body roll control system and the vehicle torque control system. The vehicle torque control system includes at least one fluid actuated clutch provided to regulate a drive torque distribution between the wheels of the motor vehicle in order to improve traction of the motor vehicle on a drive surface. The vehicle body roll control system includes at least one force device provided to tilt a vehicle body relative to a vehicle chassis so as to counteract a rollover-inducing force.

  • Patent number: 6830122
    Abstract: A yaw management system for a vehicle with driveline torque control is comprised of sensors to determine the rate of change of yaw in the vehicle, a controller for receiving information from the sensors, and a means for using that information to selectively transfer torque from the inner half shaft axles of the vehicle to the outer half shaft axles of the vehicle for regulating the torque delivered to the drive wheels.
