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.
