Abstract
A drive train control method includes transmitting a total time period of a stroke phase and a torque phase of an upshift from a transmission control unit of an automatic transmission to an engine control unit of an engine. The method also includes closing a first shift element of the automatic transmission and opening a second shift element of the automatic transmission during the upshift. A control pressure of the first shift element increases during the torque phase relative to the control pressure of the first shift element at an end of the stroke phase. A control pressure of the second shift element decreases during the torque phase relative to the control pressure of the second shift element at the end of the stroke phase. The method further includes, based at least in part on the total time period of the stroke and torque phases, increasing an actual torque of the engine during the upshift such that the actual torque of the engine increases to a higher gear torque prior to an end of the torque phase.
