Abstract
A vehicle includes a transmission, a motor configured to provide a motor torque to the transmission, and an engine configured to provide an engine torque to the transmission. A torque converter is operably disposed between the transmission and the motor, the engine, or both. The torque converter is configured to at least partially transfer at least one of the motor torque and the engine torque to the transmission in accordance with a plurality of k-factors. The torque converter includes a clutch configured to at least partially engage to change the effective k-factor applied by the torque converter. A control processor is configured to blend the plurality of k-factors and at least partially engage the clutch based on the blended k-factor.
