Model Guided torque control

Torque control system for a vehicle, comprising: an engine; coupled to the internal combustion engine electronic throttle valve; a drive train control unit which controls the electronic throttle valve; a first control loop which is operated in the drive train controller and a proportional-integral function that acts on the torque deviation in the internal combustion engine; a second control loop, which is operated in the drive train controller, and includes a proportional-integral function, which acts on the rotational fluctuation in the internal combustion engine; and a third control loop, which is operated in the drive train controller, and includes a Storgrosenaufschaltungs function for controlling the engine torque; in which the output values ​​of the first, second and third control loop are used to calculate a desired air mass flow for the engine and the desired air mass flow is used to generate a position command for the electronic throttle.
