Abstract
A vehicle includes an engine, an electric machine, a transmission, and at least one controller. The at least one controller, in response to a gear shift of the transmission that causes a speed of the engine to exceed a predetermined speed, commands a change in current to the electric machine such that the speed of the engine decreases to a target speed to avoid engine flare.
