A device and method for controlling the amount of fuel supplied to an internal combustion engine as a function of operating characteristics such as the pressure in the intake manifold, the engine speed, coolant temperature and intake air temperature, where a load signal formed from pressure and engine speed values is corrected by a correction factor F.sub.CORR as a function of the temperature, and when forming the correction factor F.sub.CORR, the influences of the engine temperature and/or the intake air temperature on the load sensing are weighted separately as a function of the operating point.

[ What is claimed is:] [1.] A device for controlling an amount of fuel provided to an internal combustion engine having operating characteristics, the amount of fuel being controlled as a function of the operating characteristics, the device comprising:first means for receiving at least one first input signal indicative of an operating characteristic of the internal combustion engine;second means for receiving a first temperature signal indicative of an intake air temperature of the internal combustion engine;third means for receiving a second temperature signal indicative of an internal temperature of the internal combustion engine;first means for generating a first output signal as a function of the first temperature signal;second means for generating a second output signal as a function of the second temperature signal;third means for generating a first weighting factor as a function of the at least one first input signal;fourth means for generating a second weighting factor separately from the first weighting factor, as a function of the at least one first input signal;first means for weighting the first output signal with the first weighting factor;second means for weighting the second output signal with the second weighting factor;means for determining a correction factor as a function of the weighted first and second output signals; andmeans for correction factor correcting a load signal of the internal combustion engine as a function of the correction factor.
