Abstract:
A vehicle control method for a vehicle having powertrain with an internal combustion engine and a transmission having a clutch, the method comprising of transitioning through a lash region of the transmission during clutch slipping conditions in response to a driver tip-in; and during the transition, first retarding ignition timing past maximum torque timing while increasing engine airflow, and then second, advancing ignition timing from the retarded timing while continuing to increase engine airflow.
