Abstract:
A method for setting torque of an internal combustion engine, comprising the steps of(a) performing in a control path a correlation of a torque with an air mass and of an air mass with a throttle valve position, wherein a set air mass is determined by the control path from a set torque and, a corresponding throttle valve position is determined and set;(b) determining an actual air mass to be delivered to the internal combustion engine for combustion;(c) determining any difference between the set air mass and the actual air mass by a comparison of the set and actual air mass value;(d) determining a correction value for the determined difference in step (c) using the correction value to perform an adaptation of the control path to the determined difference such that in the control path a throttle valve position is associated with a set torque to be established which compensates for the previously determined difference between the set air mass and the actual air mass, and(e) using an actual fuel mass fed to the internal combustion engine for combustion and a fuel/air mass ratio of a mixture fed to the internal combustion engine for combustion in order to determine the actual air mass.
