Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission, where the transmission is downstream of the engine, and where the electric machine is downstream of the transmission. In one example, responsive to a driver-demanded wheel torque that exceeds a capacity of the electric machine, a vehicle acceleration plateau is avoided by transiently connecting a crankshaft of the engine to a low speed input shaft of the transmission while the engine is accelerating to a target speed.
