1. A method of engine operation, the method comprising:
determining a speed of an engine in a vehicle system, the vehicle system including a hydraulic system and a vehicle propulsion system operatively coupled to the engine;
determining that the engine speed is decreasing based upon an engine speed value and one or more prior engine speed values prior to the engine speed value and an actual engine speed is less than a target engine speed;
determining a current gear setting and one or more operating parameters of the hydraulic system in response to determining that the engine speed is decreasing and the actual engine speed is less than the target engine speed; and
in response to the current gear setting being engaged and the one or more operating parameters being greater than a predetermined threshold value, controlling the engine speed to be higher than the target engine speed.
