  • Patent number: 8676459
    Abstract: A system and method for controlling a powertrain of a vehicle having an engine configured to output a variable torque, can include a transmission with a plurality of gear ratios and selectively driven by the variable torque, and a pair of wheels selectively driven by the transmission. The system can include a longitudinal acceleration sensor and a controller. The controller can be in electrical communication with the longitudinal acceleration sensor. The controller can be configured to determine an inertial value of the vehicle based on data from the longitudinal acceleration sensor prior to a shift from one of the plurality of gear ratios to another of the plurality of gear ratios.

  • Patent number: 8534409
    Abstract: A vehicle drivetrain can include a primary pair of drive wheels and a secondary pair of drive wheels and can be selectively switched between a two-wheel drive mode and a four-wheel drive mode. When the drivetrain is in the two-wheel drive mode, the secondary pair of wheels are disconnected from the prime mover and the multi-ratio transmission. Also, when the drivetrain is in the two-wheel drive mode, the components used to drive the secondary pair of drive wheels can be rotationally isolated from each of the secondary pair of wheels, the prime mover and the multi-ratio transmission.
