Abstract
A torque control system for a vehicle including an internal combustion engine, an electronic throttle coupled to the internal combustion engine, a powertrain controller controlling the electronic throttle, a first control loop operating in the powertrain controller including a feed forward function to control engine torque, a second control loop operating in the powertrain controller including a proportional function acting upon the torque variance in the internal combustion engine, a third control loop operating in the powertrain controller including an integral function acting upon the rpm variance in the internal combustion engine, and where the outputs of the first, second and third control loop are used to factor a desired mass airflow for the engine and the desired mass air flow is used to generate a position command for the electronic throttle.
