Abstract: A vehicle includes an engine, a transmission, and a controller. The engine is configured to generate power. The transmission is configured to transfer power from the engine to at least one drive wheel to propel the vehicle. The controller is programmed to, in response to a command to shift the transmission and a corresponding command to decrease a torque of the engine to less than a threshold corresponding to a spark retard limit during the shift, (i) increase the pressure of an oncoming clutch to engage the oncoming clutch, (ii) retard an engine spark at the spark retard limit to reduce the torque of the engine to the threshold during the engagement of the oncoming clutch, and (iii) shutdown at least one cylinder of the engine to further reduce the torque of the engine to less than the threshold during the engagement of the oncoming clutch.

Abstract: A power supply system for an electrified vehicle may include a primary power source and an auxiliary power source configured to selectively supply power in place of or in addition to the primary power source. At least one electrical connector is configured to connect the auxiliary power source to the power supply system.

Abstract: A power supply system for an electrified vehicle according to an exemplar aspect of the present disclosure includes, among other things, a primary power source and an auxiliary power source configured to selectively supply power in place of or in addition to the primary power source. At least one electrical connector is configured to connect the auxiliary power source to the power supply system.

Abstract: A controller, in response to a change from a first steady pedal condition to a second steady pedal condition, decreases a torque command during the second steady pedal condition based on a difference between a peak torque command achieved during the change and a steady torque command corresponding to the first steady pedal condition. The controller also operates a powertrain to satisfy the torque command.

Abstract: A system and method for controlling a powertrain in a vehicle includes the step of reducing or otherwise modifying a response of the powertrain to accelerator pedal input from a standard powertrain response under certain circumstances, for example, when a position of the accelerator pedal is within a predetermined range and operation of the vehicle meets at least one criteria, including at least one criteria indicative of steady state powertrain operation.

Abstract: The present disclosure relates to a computer-implemented method of controlling an engine fuel pump in a hybrid-electric vehicle. The method includes: cycling a vehicle powertrain between an electric mode, where an engine is commanded off, and a mechanical mode, where the engine is commanded on; depowering an engine fuel pump when the engine is commanded off; and determining if the engine is operating in a fuel shut-off mode.
