Abstract
A method for injecting a predetermined total fuel quantity via multiple injections using a fuel injector having a solenoid drive for an internal combustion engine of a motor vehicle is disclosed. The method includes determining a first target injection quantity to be injected per injection to inject the total fuel quantity throughout a series of consecutive injections; and performing a first subseries of consecutive injections, where the fuel injector is actuated according to the first target injection quantity. The method also includes determining a first fuel quantity injected during the first subseries of injections; determining a second target injection quantity to be injected per injection in a second subseries of consecutive injections, to inject the total fuel quantity throughout the first subseries and the second subseries of consecutive injections; and performing the second subseries of injections. The fuel injector is actuated according to the second target injection quantity.
