Expansion of on-demand capacity operation in torque control systems

摘要

A method of regulating a torque output of a variable displacement engine, comprising: calculating a torque modification term based on an engine operating parameter; Determining a desired engine torque and an estimated engine torque; Modifying the desired engine torque based on the torque modification term to provide a modified desired engine torque; and regulating an engine torque output based on the modified desired engine torque and the estimated engine torque when the engine is operating in a deactivated mode; characterized in that operation of a vehicle system is regulated based on the estimated engine torque, while the engine output torque is regulated based on the modified desired engine torque and a modified estimated engine torque during engine operation in the deactivated mode.
