Abstract
A vehicle includes an engine. The vehicle includes a controller configured to start a timer having a duration defined by a charge limit of a traction battery and during which the engine braking is maintained and reduce a predetermined rate of change speed limit of the engine is reduced. The starting of the timer is responsive to application of an accelerator pedal during engine braking. The controller is further configured to increase the predetermined rate of change speed limit such that engine braking is predicted based on the limit of the battery, responsive to application of an accelerator pedal during engine braking.
