A vehicle including an engine, an electric machine, a traction battery, and a controller is provided. The controller is programmed to, during acceleration or constant speed travel of the vehicle and responsive to state of charge of the battery falling below a first threshold, run the engine to charge the battery. The controller is further programmed to, during the running and responsive to first occurrence of the state of charge achieving a second threshold, accelerator pedal release, or braking of the vehicle, stop the engine. The controller may be further programmed to, during accelerator pedal release or braking of the vehicle and responsive to the state of charge falling below the first threshold, inhibit start of the engine. The controller may be further programmed to, during the inhibiting and responsive to acceleration or constant speed travel of the vehicle, run the engine to charge the battery.
