Abstract: A vehicle is provided with a powertrain including a battery-powered electric motor, an internal combustion engine, a transmission, and a powertrain controller. The controller is programmed to permit an upshift of a transmission gear ratio while a powertrain torque demand is less than a forecasted available powertrain torque sustainable over a predetermined upcoming duration of time. The controller is also programmed to inhibit an upshift while the torque demand exceeds the forecasted available powertrain torque to reduce successive gear shifts. The controller may be further programmed to, in response to battery a state of charge being less than a threshold, reduce the forecasted available powertrain torque by an amount sufficient to provide a recharge to a battery. The controller may be further still programmed to reduce the forecasted available powertrain torque by an amount sufficient to restart the engine while the powertrain is operating in an engine-off traction mode.

Abstract: A method includes controlling a torque output of an electric machine of an electrified vehicle based on estimated loads present during a transmission engagement of the electrified vehicle. Controlling the torque output may include merging a first feed-forward torque with a feedback torque if an input shaft of a transmission gearbox is spinning, or merging a second, different feed-forward torque with the feedback torque if the input shaft is not spinning.

Abstract: A hybrid vehicle powertrain is configured to provide a regenerative-braking torque limit on a transmission during a regenerative-braking downshift. The regenerative-braking downshift event has sequential boost, start, torque, inertia, and end phases. The transmission may be operated in absence of a regenerative-braking torque limit during the boost and start phases to recapture more energy. The transmission may be operated with a regenerative-braking torque limit during the torque and inertia phases to protect for an input shaft speed dip that may occur without the limit. The limit may be removed once the regenerative-braking downshift event is completed.

Abstract: A hybrid vehicle includes an engine coupled to a planetary gearset and an electric motor configured to provide motor torque directly to a torque transfer set. An overdrive clutch is configured to, when engaged, bypass at least a portion of engine torque to an overdrive shaft directly connected to the torque transfer set. This allows the engine to also provide torque directly to the torque transfer set along with the motor in an overdrive mode of operation. At least one controller is programmed to control the motor and/or the engine based on an estimated amount of torque transferred through the overdrive clutch.

Abstract: A vehicle includes a power source, such as an engine, an electric machine, or combination thereof. A torque converter is selectively coupled to the power source such that drive torque can be altered before being distributed into a transmission of the vehicle. A torque converter bypass clutch enables torque from the power source to selectively transmit directly to the transmission with little or no torque altering provided by the torque converter. At least one controller in the vehicle is in communication with a storage device. The controller sends road condition data to the storage device regarding a road segment. During a subsequent drive to or over the road segment, the controller receives the road condition data and enables the torque converter bypass clutch to slip to dampen driveline disturbances when the vehicle passes over the road segment.
