Abstract: In at least one embodiment, a vehicle powertrain includes an engine and an electric machine mechanically coupled by a clutch. The powertrain also includes a torque converter configured to fluidly couple the electric machine to an output shaft. A controller is programmed to command a rotational speed output of the electric machine to the torque converter based on a predicted torque delivered across the clutch. The controller is further programmed to modify the command based on a difference between the commanded rotational speed output and an actual rotational speed output of the electric machine.

Abstract: A method of controlling a vehicle, in which the vehicle includes an engine, a traction motor, and a clutch configured to selectively couple the engine to the motor, includes commanding the traction motor to provide an incremental torque. The motor is commanded to provide the incremental torque in response to the clutch being in a slipping condition. The magnitude of the commanded incremental torque is in response to the lesser of first and second torques. The first torque corresponds to an engine torque, and the second torque corresponds to a clutch torque capacity.

Abstract: A vehicle includes a powertrain including an electric machine and a traction battery. The vehicle also includes at least one controller programmed to, during a transmission shift event, cause the electric machine to absorb torque. The torque absorption causes current generated by the electric machine to charge the battery according to a predetermined power transfer schedule defining a charge limit. The controller is further programmed to permit the current to exceed the charge limit for a predetermined duration of time in certain instances.

Abstract: A hybrid vehicle includes an engine and an electric machine, both capable of propelling the vehicle. The electric machine provides creep torque to propel the vehicle at a slow speed or hold the vehicle when on an incline. At least one controller is programmed to cancel or otherwise inhibit the electric machine from generating the creep torque in response to a brake torque or brake torque request exceeding a calibratible threshold. The calibratible threshold varies based upon vehicle incline, vehicle mass, and/or vehicle speed.

Abstract: A hybrid vehicle includes an engine and an electric machine, both capable of propelling the vehicle. The electric machine is electrically connected to a high voltage traction battery. The state of charge of the battery can decrease if the battery is used to power the electric machine, and can increase if the electric machine supplies power to the battery via regenerative braking. Constraints are placed on the vehicle such that the battery operates within a preferred operating window, defined between minimum and maximum state of charge thresholds. At least one controller is programmed to alter the preferred operating window of the battery in response to various vehicular activities, such as when the vehicle is towing another object, or when the vehicle weighs above a certain threshold due to contents within the vehicle, for example.

Abstract: A vehicle includes an engine, an electric machine, a battery, and at least one controller. The vehicle may further comprise a port for supplying power to a load external to the vehicle. The controller is programmed to operate the engine at a power level based on a difference between a battery voltage and a reference voltage such that a power output by the electric machine reduces the difference. The power level may define an engine operating point that minimizes fuel consumption. The operating point may be an engine torque and an engine speed. The power level may be further based on a state of charge of the battery. The electric machine may be operated to cause the engine to rotate at an engine speed corresponding to the selected power level. The difference may be caused by varying power drawn by a load external to the vehicle.
