METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for operating an internal combustion engine (1), especially an internal combustion engine pertaining to a motor vehicle, by means of a control appliance (2) for controlling/regulating the operation of the internal combustion engine (1) according to an air mass sensor signal (L_1) of a first air mass sensor (HFM_1). A first auxiliary signal (H_1), obtained from an additional sensory mechanism or from models of the internal combustion engine (1) by means of calculation, enables a plausibility control to be carried out or the substitution of the air mass sensor signal (L_1) if interference is detected in terms of said signal (L_1), thus ensuring that the internal combustion engine (1) can continue to be operated in an optimum manner.
