Abstract
In a method for operating a starter of a vehicle, a physical variable is measured, and a starter current of the starter is limited or not limited as a function of the measured physical variable, the limiting action being terminated after a predetermined period of time in the event that the starter current is limited.

A method for operating a starter of a vehicle, comprising:
- measuring a physical variable;
- performing an initial selective switching, as a function of the measured physical variable, to a limiting operating mode in which a starter current of the starter is limited;
- and
- terminating the limiting of the starter current after a predetermined period of time;
- wherein a subsequent selective switching to the limiting operating mode is performed as a function of the starter current dropping below a specified threshold value after the termination of the limiting action following the initial selective switching.
A device for operating a starter of a vehicle, comprising:
- a limiter for limiting a starter current;
- a jumper for selectively electrically jumpering the limiter, wherein the starter current is not limited during jumpering;
- a control unit for selectively switching the jumper between a jumpering mode and a non-jumpering mode as a function of a measured physical variable, wherein the control unit is configured to:
- (i) perform an initial selective switching, as a function of the measured physical variable, to the non-jumpering mode to achieve a limiting mode in which a starter current of the starter is limited;
- (ii) terminate the limiting of the starter current after a predetermined period of time by switching to the jumpering mode;
- and (iii) perform a subsequent selective switching to the non jumpering mode to achieve the limiting mode as a function of the starter current dropping below a specified threshold value after the termination of the limiting action following the initial selective switching.
A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, performs a method for operating a starter of a vehicle, the method comprising:
- measuring a physical variable;
- performing an initial selective switching, as a function of the measured physical variable, to a limiting operating mode in which a starter current of the starter is limited;
- and
- terminating the limiting of the starter current after a predetermined period of time;
- wherein a subsequent selective switching to the limiting operating mode is performed as a function of the starter current dropping below a specified threshold value after the termination of the limiting action following the initial selective switching.
