Abstract
A method for controlling an injection system of an internal combustion engine having at least one injector, the fuel metering being divided into a first partial injection and at least one second partial injection, and a control signal which determines the fuel quantity to be injected with the aid of the at least one injector being corrected as a function of a pressure wave influencing the at least two partial injections, the pressure wave correction being performed on the basis of a periodic model which models the quantity wave as a sum of periodic functions.
Claims8
A method for controlling an injection system of an internal combustion engine having at least one injector, the method comprising:
- dividing a fuel metering into a first partial injection and at least one second partial injection;
- correcting a control signal which determines a fuel quantity to be injected with the aid of the at least one injector as a function of a pressure wave influencing the first and second partial injections;
- and
- performing a pressure wave correction on the basis of a periodic model which models a quantity wave as a sum of periodic functions.
A control unit for controlling an injection system of an internal combustion engine having at least one injector, the control unit comprising a computing/control device for performing the following:
- dividing a fuel metering into a first partial injection and at least one second partial injection;
- correcting a control signal which determines a fuel quantity to be injected with the aid of the at least one injector as a function of a pressure wave influencing the first and second partial injections;
- and
- performing a pressure wave correction on the basis of a periodic model which models a quantity wave as a sum of periodic functions.
A computer-readable medium storing a computer program which, when executed by a processor, performs the following steps for controlling an injection system of an internal combustion engine having at least one injector:
- dividing a fuel metering into a first partial injection and at least one second partial injection;
- correcting a control signal which determines a fuel quantity to be injected with the aid of the at least one injector as a function of a pressure wave influencing the first and second partial injections;
- and
- performing a pressure wave correction on the basis of a periodic model which models a quantity wave as a sum of periodic functions.
