Title: METHOD FOR DETERMINING AN INJECTION AMOUND OF AT LEAST ONE INJECTOR OF A FUEL METERING SYSTEM OF AN INTERNAL COMBUSTION ENGINE OF A VEHICLE
Abstract:
The invention relates to a method for determining an injection amount of at least one injector (18) of a fuel metering system of an internal combustion engine (10) of a vehicle, wherein the internal combustion engine (10) is torque-transmittingly coupled to an electric machine (40), wherein, when the vehicle is stationary, the internal combustion engine (10) is operated with a predetermined rotational speed and a predetermined load, and a value of a current generated by the electric machine (40) is determined, and wherein the injection amount of the at least one injector (18) is derived from the value of the current generated by the electric machine (40).
