1. A method of operating a hybrid vehicle driveline, comprising:
opening a torque converter clutch of a torque converter that is closed in response to an engine start request; adjusting a driveline integrated starter/generator (DISG) speed in response to a desired torque converter impeller speed while the torque converter clutch is open in response to the engine start request, and where the DISG is mechanically coupled to an impeller of the torque converter and a transmission input shaft is coupled to a turbine of the torque converter; and closing a driveline disconnect clutch in response to the engine start request.
