Abstract
A vehicle includes a transmission and a controller. The controller is configured to receive a torque request, calculate a Specific Fuel Consumption (SFC) for satisfying the torque request in an initial gear and in an alternate gear, and command the transmission to shift from the initial gear into the alternate gear in response to the calculated SFC for satisfying the torque request in the alternate gear being less than the calculated SFC for satisfying the torque request in the initial gear.
