Abstract: A differential includes a disconnect feature. When in a disengaged state, the drive gear is decoupled from the differential carrier. As a result, the portions of the powertrain that would provide propulsion through the differential may be stationary and parasitic drag is decreased. The differential is transitioned into an engaged state by providing electrical current in a solenoid coil fixed to the housing. A solenoid piston acts through a thrust bearing to slide a sleeve, thereby coupling the carrier to the drive gear.

Abstract: A controller detects a rotor magnet temperature based on an actively detected back electromotive force (BEMF) voltage of the motor. The controller detects the BEMF voltage by commanding the injection of a direct-axis (d-axis) current into the motor while the motor is spinning but otherwise commanding no torque. The controller actively detects the BEMF voltage in that the controller purposely injects a known quantity of d-axis current at a chosen time during which the controller detects or is aware that the motor is commanding no torque. Using a quadrature-axis (q-axis) voltage equation, which describes the relationship between a voltage command, the current, the BEMF voltage, and reactance in the q-axis, the controller solves for the BEMF voltage with the voltage command, the current, and the q-axis reactance being known to the controller. The controller detects the rotor magnet temperature based on the BEMF voltage.

Abstract: A method and apparatus for providing an off-road feature of a vehicle includes determining that the vehicle is in an off-road area based upon a location of the vehicle and sensed terrain characteristics at the location. Upon determining that the vehicle is in the off-road area, the vehicle monitors parameters for enablement of the off-road feature of the vehicle. The off-road feature is enabled in response to the parameters being within a predetermined range based upon a number of transitions between an enabled state and a disabled state within a predetermined time being less than a transition threshold. Parameter monitoring for enablement of the off-road feature is ceased upon determining that the vehicle has moved from the off-road area to an on-road area.
