Classification: CPC B  F | IPC B  F

Claim 0:
1. A vehicle comprising:
an engine configured to generate power;
a transmission (i) configured to transfer power from the engine to at least one drive wheel to propel the vehicle and (ii) having a plurality of clutches configured to shift the transmission between a plurality of gear ratios;
an accelerator pedal configured to generate a command corresponding to a desired engine torque in response to depression of the accelerator pedal; and
a controller programmed to,
in response to a command to shift the transmission, (i) increase a pressure of an oncoming clutch to engage the oncoming clutch and (ii) reduce a torque of the engine from the desired engine torque to a reduced value,
in response to the reduced value exceeding a threshold, retard an engine spark and maintain operation of all cylinders of the engine to reduce the torque of the engine during the engagement of the oncoming clutch,
in response to the reduced value being less than the threshold, retard the engine spark and shutdown at least one cylinder of the engine to reduce the torque of the engine during the engagement of the oncoming clutch, and
in response to completing the shift of the oncoming clutch, increase the torque of the engine to the desired engine torque.
