Abstract
A method for controlling and/or regulating a d.c. converter for at least two electromagnetic valves of an internal combustion engine of a motor vehicle is provided. A current generated by the d.c. converter is supplied to each valve. A determination is made as to when the total currents supplied to the valves constitute a high load for the d.c. converter. If this is the case, the d.c. converter is influenced in the sense of better processing of the high load.

1-11. (canceled)
A method for regulating a d.c. converter for at least two electromagnetic valves of an internal combustion engine, the method comprising:
- supplying each of the at least two electromagnetic valves with a current that is generated by the d.c. converter;
- determining when a total current supplied to the at least two electromagnetic valves constitutes a high load for the d.c. converter;
- and
- if a high load is determined, adapting the d.c. converter for processing of the high load.
A computer-readable storage medium for storing computer program having instructions for controlling, when the program is executed by a computer, a method comprising:
- supplying each of the at least two electromagnetic valves with a current that is generated by the d.c. converter;
- determining when a total current supplied to the at least two electromagnetic valves constitutes a high load for the d.c. converter;
- and
- if a high load is determined, adapting the d.c. converter for processing of the high load.
A device for regulating a d.c. converter for at least two electromagnetic valves of an internal combustion engine in a motor vehicle, a current generated by the d.c. converter being supplied to each of the at least tow electromagnetic valves, the device comprising:
- a control unit configured to determine when a total current supplied to the at least two electromagnetic valves represents a high load for the d.c. converter, wherein the control unit regulates the d.c. converter for optimal processing of the high load.
