Abstract
A vehicle includes an engine, an electric machine, and a controller. The engine and the electric machine are configured to simultaneously generate power in a hybrid mode. The controller is programmed to, responsive to a power demand decreasing to less than a first threshold while the vehicle is operating in the hybrid mode, shutdown the engine. The controller is further programmed to, responsive to the power demand decreasing to less than the first threshold and an operator input to extend the hybrid mode, override shutting down the engine.
