Abstract: A powertrain system is described, and includes an internal combustion engine and an electric machine configured to generate propulsion torque responsive to a driver torque request. A method for operating the powertrain system includes determining, in response to a request to execute an engine autostart operation, whether a driveline torque sag may occur. The method further includes forgoing executing the engine autostart operation when it is determined that a driveline torque sag will occur during the execution of the engine autostart operation.

Abstract: A multi-mode powertrain system is described, and includes an internal combustion engine and electric machines operative to transfer mechanical power through a gear train to an output member coupled to a driveline, wherein the electric machines electrically connect to a battery. The method includes determining an audible noise-based maximum engine speed, wherein the internal combustion engine generates an audible noise that is less than a threshold noise level when operating at a speed that is less than the audible noise-based maximum engine speed. The electric machines and the internal combustion engine are controlled responsive to an operator torque request including controlling the engine speed to be less than the audible noise-based maximum engine speed when battery power is greater than a minimum threshold.

Abstract: A method for controlling operation of a multi-mode powertrain system includes periodically determining a power cost difference between a first power cost and a second power cost. This includes determining the first power cost associated with operating the powertrain system with the engine operating in a presently commanded engine state in response to an operator torque request and determining the second power cost associated with an expected powertrain operation with the engine operating in a non-commanded engine state in response to the operator torque request. The first power cost is compared with the second power cost, and successive iterations of the periodically determined power cost difference between the first power cost and the second power cost are integrated to determine an integrated power cost difference. A transition to the non-commanded engine state is commanded when the integrated power cost difference is greater than a threshold.

Abstract: A method of controlling a transmission includes detecting an occurrence of a downshift in the transmission from a first gear ratio to a second gear ratio. A determination is made whether the vehicle is operating within a freeway speed range, and whether an accelerator pedal is depressed at least a minimum percentage of a fully depressed position. When the downshift from the high gear ratio to the low gear ratio is detected, the vehicle is operating within the freeway speed range, and the accelerator pedal is depressed at least the minimum percentage of the fully depressed position, a countdown timer is started to count down from a pre-defined time to zero. An upshift of the transmission from the second gear ratio to the first gear ratio is restricted while the countdown timer defines a time that is greater than zero.
