Abstract
An engine control system of a vehicle comprises a first module and a cylinder deactivation module. The first module selectively adjusts torque output by an engine based on a vehicle torque request that is greater than a driver torque request. The cylinder deactivation module selectively deactivates a cylinder of the engine when a difference between an estimated maximum torque output of the engine and the driver torque request is greater than a predetermined maximum torque.
