1. A method for operating a vehicle, comprising:
via one or more controllers, generating a rate limited driver demand torque in response to an engine start request;
cranking an engine via increasing a torque transfer capacity of a driveline disconnect clutch and increasing a torque output of an electric machine as the torque transfer capacity of the driveline disconnect clutch is increased; and
decreasing the torque transfer capacity of the driveline disconnect clutch and outputting a substantially constant torque via the electric machine in response to an indication of combustion occurring in the engine.
