Abstract

An apparatus, method, and system for controlling an idle speed of an internal combustion engine during certain vehicle component operations to minimize unwanted motion and vibration. A transmission neutral engagement, a transmission forward or reverse gear engagement, and a vehicle speed are detected. An engine target idle speed is set to a first speed during the neutral engagement. An engine target idle speed is set to a second idle speed when a vehicle speed is less than a threshold speed and the forward or reverse gear is activated. The vehicle target idle speed is set to a third idle speed when the vehicle speed is greater than a threshold speed while the forward or reverse gear is activated, wherein the first target idle speed, second target idle speed and third target idle speed are different engine speeds.
