Abstract
A method of changing an active cylinder count of an engine may include determining a vehicle vibration limit and a vehicle vibration level. The cylinder count may be modified (increased or decreased) based upon the vehicle vibration limit and the vehicle vibration level. The vehicle vibration limit may be based upon a vehicle speed, and a coolant temperature of the engine. The vehicle vibration level may be based upon at least one of a desired torque of the engine and a number of active cylinders of the engine. According to other features, the vehicle vibration level may be based upon a measured vibration level of a vehicle component.
