1. A device for determination of torque of an internal combustion engine, said device comprising
a first sensor mechanism for acquisition of a first measured variable relating to angular velocity of the internal combustion engine,
a second sensor mechanism for acquisition of a second measured variable relating to charge pressure of the internal combustion engine or a simulation mechanism for simulation of a charge pressure quantity as a function of the first measured variable and
a data processing mechanism connected to the first and second sensor mechanisms or to the first sensor mechanism and to the simulation mechanism for determination of torque from the first measured variable and the second measured variable or from the first measured variable and the simulated charge pressure variable.
