Abstract:
1. A method for the torque-based control of an internal combustion engine ( 1 ) comprising the steps of: calculating from an input value (FP) representing a desired engine power output a desired torque value (MSW), converting the desired torque value (MSW) to a first power output determining signal (ve 1 ) via a performance graph ( 8 ) taking into consideration an additional value, correcting the first power output determining signal (ve 1 ) by way of a relative efficiency (ETAr) to form a second power output determining signal (ve 2 ), calculating from the second power output determining signal (ve 2 ) a main power output determining signal (ve) and determining the control of the output torque of the internal combustion engine ( 1 ) from the power output determining signal (ve), said additional value corresponding to a relative friction moment (MFr) which is calculated essentially from a deviation of the actual state of the internal combustion engine ( 1 ) from a standard state in which the relative friction moment (MFr) is zero.
