Abstract
A hybrid electric vehicle (HEV) includes an internal combustion engine, a traction motor, a generator, and a traction battery. Available electric power in the HEV is based upon the available power in the traction battery. The engine and the motor may both work simultaneously to propel the HEV. While the engine is powering the HEV, a controller is configured to increase a power output of the engine based upon a difference between available battery power and a combination of desired motor power and desired generator power.
