Abstract
A control system for an engine of a vehicle includes a requested torque module that determines a first requested torque based on an accelerator pedal position and a current engine torque output capacity. An accelerator effective position module determines an accelerator effective position based on a requested driver axle torque request signal. A power enrichment (PE) module enables a PE mode to provide a richer than stoichiometric fuel equivalence ratio based on the first requested torque and the accelerator effective position.
