Abstract
An engine torque control module comprises a derivative module and a cylinder torque module. The derivative module determines a derivative term for a first cylinder of an internal combustion engine based on rotation of a crankshaft and determines an average derivative term for the first cylinder based upon the derivative term. The cylinder torque module determines an operating condition of the first cylinder based on the average derivative term, adjusts a torque output of the first cylinder based on the operating condition, and adjusts a torque output of a second cylinder based on the operating condition.
