Abstract
A vehicle includes an engine, an electric machine, and a controller. The engine and the electric machine are each configured to generate power. The controller is programmed to, responsive to a power demand exceeding a first threshold while the electric machine is generating power alone, start the engine. The controller is further programmed to, responsive to the power demand exceeding the first threshold and an operator input to suppress an engine startup, override starting the engine for a predetermined period of time.
