Abstract
A vehicle includes an engine, an electric machine, a clutch, and a controller. The clutch is disposed between the engine and the electric machine. The controller is programmed to, in response to an engine start, close the clutch to transfer power from the electric machine to the engine to start the engine. The controller is further programmed to, in response to the engine start, control a torque capacity of the clutch during the engine start according to a model of a pressure applied to the clutch. The controller is further programmed to, in response to the engine start, control the torque of the electric machine based on an adjusted torque capacity of the clutch.
