Abstract
A system and method for controlling a multi-cylinder internal combustion engine include determining a currently available maximum torque, determining a driver demanded torque based on a current accelerator pedal position and reference ambient conditions, and controlling the engine to deliver the lesser of the driver demanded torque corresponding to the reference ambient conditions and a calibratable percentage of the currently available maximum torque corresponding to the current ambient conditions. A similar torque is provided at high altitudes as that provided at sea level for a given low pedal position while smoothly blending into the currently available peak torque.
