A method for controlling a multi-cylinder internal combustion engine having electronically controlled airflow comprising limiting a currently available maximum engine torque below maximum torque based on a limited torque output condition, the limited torque output condition not being based on current ambient temperature or pressure conditions. The method also includes determining a driver demanded torque based on a current throttle position. The method further includes controlling the engine to deliver the driver demand torque if the internal engine condition does not indicate the limited torque output condition or to deliver a calibratable percentage of the currently available maximum torque if the internal engine condition indicates a limited torque output condition.

Acceleration pedal interpretation when engine torque is limited

Rapidly changing torque demand is coordinated in an automotive vehicle having an engine and at least one motor. An engine base torque level indicating slowly changing torque produced by the engine is received. A motor torque is determined as a difference between a fast desired torque and the engine base torque level. An engine fast torque is determined as a difference between the request for fast desired torque and the motor torque. The motor torque is determined as a motor torque request and the engine fast torque is determined as an engine torque request.

Vehicle fast torque coordination

Hybrid vehicles and other vehicles with one or more torque producing devices operate more effectively with proper resolution of torque requests. In one aspect of the present invention, a plurality of vehicle force and torque requests are resolved at different levels depending on the vehicle architecture. In another aspect of the present invention, torque requests are resolved into base requests and fast requests depending upon response times of torque devices satisfying these requests.

Vehicle torque resolution

A method of controlling torque output of an engine including receiving an acceleration pedal position signal and receiving an engine speed signal. The method also includes calculating a modified engine speed signal as a function of the engine speed signal and the acceleration pedal position signal. The method further includes requesting engine output torque as a function of the acceleration pedal position signal and the modified engine speed signal.
