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.

Abstract: A method for operating a powertrain system includes executing a transmission shift between an initial electrically-variable transmission (EVT) range and a target EVT range. The transmission shift includes transitioning to operating with three speed degrees of freedom including controlling speed of a second torque machine to synchronize speed of an oncoming clutch associated with the target EVT range and coincidentally controlling speeds of a first torque machine and an engine to achieve a preferred speed of the output member of the transmission. The transmission shift further includes controlling torque output from the first torque machine in response to an output torque request, and activating the oncoming clutch upon synchronizing the speed of the oncoming clutch. Subsequent to the transmission shift, the powertrain system is operated in the target EVT range.

Abstract: A powertrain system includes an internal combustion engine, a first electric machine and an electro-mechanical transmission operative to transmit torque to a driveline. A method for controlling the powertrain system in the presence of a controlled neutral operation of the electro-mechanical transmission being selected includes monitoring vehicle speed, and only when the monitored vehicle speed is indicative of a low-speed zone restricting a transition from a current engine operating state.

Abstract: A method for controlling a powertrain system in response to a command to execute a multi-state shift event for the transmission includes determining an initial output torque limit and determining an initial commanded output torque based upon the initial output torque limit. The powertrain system is controlled to generate torque in response to the initial commanded output torque prior to completion of a first state transition of the multi-state shift event that includes a commanded torque reduction. After completion of the first state transition of the multi-state shift event that includes the commanded torque reduction, a torque ramp rate is determined, and the initial commanded output torque is adjusted based upon the torque ramp rate. The powertrain system is controlled to generate torque in response to the initial commanded output torque and the adjusted initial commanded output torque during a remainder of the multi-state shift event.

Abstract: A method to monitor a torque transfer device configured to transfer torque within an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and at least one electric machine includes executing a failure detection strategy in response to a detected slip condition of the torque transfer device. The failure detection strategy includes monitoring a magnitude of energy loss of the torque transfer device. A failure condition in the torque transfer device is detected when the magnitude of energy loss achieves a predetermined energy threshold.
