Abstract: A powertrain system includes an internal combustion engine having a crankshaft that fixedly couples to an input member of a multi-mode transmission including first and second torque machines. The transmission operates in one of a plurality of fixed-gear modes and variable modes through selective activation of first and second clutches. A control method includes, in response to a command to operate the multi-mode transmission in a fixed-gear mode, activating only the first clutch and commanding the engine to an OFF state. The first torque machine is controlled to generate a first torque output responsive to a drag torque that is offset by an engine reactive torque with the engine in the OFF state. The transmission operates in the fixed-gear mode by controlling the second torque machine to generate a second torque output responsive to an operator torque request and the first torque output of the first torque machine.

Abstract: A method of managing an operating state of an electrified powertrain includes a controller identifying a plurality of available operating regions defined by at least one available operating state of the powertrain, each operating region representing a distinct range of operating conditions. The available operating regions include an avoidance region defining a plurality of unwanted operating conditions and separating a first allowable operating region from a second allowable operating region such that the first and second allowable operating regions are noncontiguous. The method identifies at least one ideal operating condition in each of the available operating regions, determines a preferability factor and stabilization factor for each of a current and each of the ideal operating conditions, and arbitrates the factors to identify one of the current and ideal operating conditions as an optimized operating condition to produce a required parameter value.

Abstract: A powertrain system is described, including a method for controlling a control variable for an element thereof. The method includes determining an initial state transition threshold and an associated hysteresis band for an operating parameter related to the control variable. The hysteresis band is decayed based upon operation in a present state of the control variable for powertrain element, and a preferred control variable for the powertrain element is selected based upon a comparison of the operating parameter and the initial state transition threshold accounting for the decayed hysteresis band for the operating parameter. The element of the powertrain system is controlled to the preferred state for the control variable.

Abstract: A vehicle includes an internal combustion engine coupled to an input member of a multi-mode transmission configured to transfer torque to an output member coupled to a ground wheel with the internal combustion engine in an ON state generating an input torque. A method for controlling the vehicle includes identifying an undesirable operating region including an input/output torque region for operating the multi-mode transmission. In response to an operator request for creep torque, motor torque is controlled from a torque machine coupled to the multi-mode transmission such that the multi-mode transmission is operating outside the undesirable operating region while a mechanical braking torque to the ground wheel is coincidentally controlled in response to an operator-commanded braking, the input torque from the engine, and the motor torque from the torque machine.
