Abstract
A method of controlling engine crankshaft torque on a vehicle requests crankshaft torque modification using multiple types of torque actuators prior to and during a single commanded shift, such as an upshift. Appropriate levels of torque modification for the request, as well as appropriate times to make determinations regarding actuator type and make crankshaft torque reduction requests are determined in light of timing of key events during the shift.
