Methods and systems are provided for operating a vehicle driveline where the vehicle driveline does not include a torque converter. In one example, a method comprises controlling a capacity of a clutch configured to transmit torque between an engine and a transmission, and an output of an electric motor positioned in a driveline of the hybrid vehicle during a vehicle launch to emulate a performance of a torque converter positioned in the driveline of the vehicle. In this way, vehicle launch maneuvers may be conducted for vehicles that are equipped with a clutch and an electric motor, such that said launch maneuvers mimic those of a vehicle with a torque converter, which may improve customer satisfaction and improve engine efficiency.
