Abstract
A system and method for controlling the speed of an engine includes determining a desired engine power output and engine speed, and determining whether the desired engine speed is within one of a number of predetermined engine speed ranges. It is then determined whether a noise-vibration level for the vehicle is within a target range when it is determined that the desired engine speed is within one of the predetermined engine speed ranges. The noise-vibration level is a function of at least one of a corresponding vibration level for one or more vehicle mechanical systems, and a noise level for the passenger compartment for the engine operating at the desired engine speed. The engine is then controlled at the desired engine speed when the determined noise-vibration level is within a target range, and it is determined that the desired engine speed is within one of the predetermined engine speed ranges.
