Abstract
Methods and systems are provided for enabling a smooth transmission shift in a hybrid vehicle configured with a motor hybrid transmission. During an initial part of a transmission upshift, spark timing may be advanced from MBT to expedite torque reduction. Once engine speed has sufficiently reduced, and is within a threshold range of the desired engine speed, spark timing may be retarded until the transmission shift is completed.
