An actuator is provided for preventing rotation of a rotary component and includes a first pawl pivotable about a first pivot axis and engageable with the rotary component for preventing rotation of the rotary component in a first rotary direction. A second pawl is pivotable about a second pivot axis and engageable with the rotary component for preventing rotation of the rotary component in a second rotary direction opposite the first rotary direction. The pawls are each biased toward an engaged position with the rotary component by a pawl spring. A first and a second solenoid each include an electrically activated solenoid and an armature movable from a first position for holding the pawls out of engagement with the rotary component to a second position for allowing the pawls to be engaged with the rotary component.

Method for detecting a fault condition in a vehicular hydraulic circuit during a drive cycle using an electric pump includes monitoring an actual pump torque and monitoring a desired pump torque. A current confidence factor is determined based on the actual pump torque and the desired pump torque. An average confidence factor is iteratively calculated based on the current confidence factor and previously determined confidence factors. The average confidence factor is compared to a fault condition threshold. An absence of the fault condition in the hydraulic circuit is detected when the average confidence factor is at least the fault condition threshold, and a presence of the fault condition in the hydraulic circuit is detected when the average confidence factor is less than the fault condition threshold.

Methods and systems for operating an inverter having a plurality of high switches and a plurality of low switches coupled to an electric motor are provided. An event indicative of deceleration of the electric motor is detected. The inverter is alternated between a first mode of operation and a second mode of operation during the deceleration of the electric motor. In the first mode of operation, each of the plurality of high switches is activated and each of the plurality of low switches is deactivated or each of the plurality of low switches is activated and each of the plurality of high switches is deactivated. In the second mode of operation, each of the plurality of high switches is deactivated and each of the plurality of low switches is deactivated.

A method for determining a voltage level across an electrical circuit of a powertrain includes measuring a plurality of voltage levels and utilizing a comparison test between at least two voltage levels of the plurality of voltage levels to determine the circuit voltage level.

Method for determining a voltage level across an electric circuit of a powertrain

A method of externally charging a powertrain includes monitoring a voltage level of a first battery, determining when the monitored voltage level is below a first voltage threshold, and when the monitored voltage level is below the first voltage threshold, charging the first battery by supplying power from an external power source and increasing voltage of the power supplied by the external power source within the powertrain.

Method of externally charging a powertrain

A powertrain includes an electromechanical transmission operative to transmit torque between an input member and an electric machine and an output member to transmit tractive torque. The electric machine is electrically connected to an inverter device which is electrically connected to an energy storage device. A method for operating the powertrain includes detecting a shutdown event, commanding the transmission to neutral, commanding the electric machine to cease operating in a torque generating mode, and electrically disconnecting the energy storage device from the inverter device.

Method to manage a high voltage system in a hybrid powertrain system

A method of charging a powertrain includes detecting an external power source in electrical communication with the powertrain, establishing a virtual network between charging control module, and transferring charge from the external power source to the powertrain.
