Abstract: Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods provide a way of determining whether or not an engine has stalled while a vehicle may be propelled via the motor/generator. In one example, an engine stall may be indicated responsive to a first estimated engine torque and a second estimated engine torque.
