Abstract: A multi-mode powertrain system includes a transmission configured to transfer torque among an internal combustion engine, torque machines and an output member. A method for controlling the powertrain system includes determining a desired acceleration profile for the internal combustion engine, determining a constrained acceleration profile by imposing prioritized constraints on the desired acceleration profile, integrating the constrained acceleration profile to determine a preferred speed profile, determining a preferred acceleration profile including a derivative of the preferred speed profile constrained by minimum and maximum hard acceleration constraints, and controlling operation of the internal combustion engine in response to the preferred acceleration profile and the preferred speed profile.

Abstract: A method of controlling a vehicle park system in a shift out of park includes receiving a shift out of park request, and commanding a park actuator to rotate an actuator shaft operatively connected to a park pawl movable from an engaged position in which the park pawl is engaged with a park gear, to a disengaged position in which the park pawl is disengaged from the park gear. The method includes determining whether a detent lever operatively connected to the park pawl has moved towards an out of park position within a predetermined period of time after commanding the park actuator to rotate the actuator shaft, and then commanding an electric propulsion motor to apply torque to the transmission output shaft to assist the park actuator if the detent lever has not moved towards the out of park position within the predetermined period of time.

Abstract: An electric motor control system for a vehicle includes a vehicle speed module that determines a vehicle speed. A closed loop (CL) module determines a CL torque based on a difference between a target vehicle speed and the vehicle speed. A motor torque module determines a motor torque based on the CL torque and a motor torque request determined based on a position of an accelerator pedal. A switching control module controls switching of an inverter based on the motor torque to control application of power to an electric motor of the vehicle.

Abstract: A method for adjusting hydraulic line pressure applied to one or more clutch devices in an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and at least one electric machine includes predicting a first plurality of powertrain parameters for an upcoming event. For each of a plurality of engine torques, a predicted output torque and a predicted clutch load are determined that minimize a total powertrain operating cost based on an operator torque request and the predicted first plurality of powertrain parameters. Hydraulic line pressure is adjusted based on the engine torque having a lowest powertrain operating cost among the plurality of available engine torques.
