摘要
A method of operating a series type hybrid-electric powertrain having an internal combustion engine, a generator, and a battery is provided. A state of charge level of a battery is estimated. The state of charge level estimate is compared to a first threshold. An internal combustion engine operates at a first engine speed setpoint and a first engine torque output setpoint when the state of charge level estimate is below the first threshold. The state of charge level estimate is compared to a second threshold. The second threshold is a lower state of charge level than the first threshold. The internal combustion engine operates at a second engine speed setpoint and a second engine torque output setpoint when the state of charge level estimate is below the second threshold. The internal combustion engine generates more torque at the second torque output setpoint.
