1. A method for monitoring operation of at least one electrical load for a vehicle, the method comprising:
performing, via a comparator, a comparison of an actual value of an operating parameter, representing a physical variable, of the at least one electrical load with four threshold values related to a set value of the operating parameter, a first threshold value of the four threshold values representing a first positive deviation from the set value, a second threshold value of the four threshold values representing a first negative deviation from the set value, a third threshold value of the four threshold values representing a second positive deviation from the set value that is greater than the first positive deviation, and a fourth threshold value of the four threshold values representing a second negative deviation from the set value that is greater than the first negative deviation;
generating, via a monitor signal generator, a monitoring signal, dependent on a result of the comparing, based on (i) a first signal characteristic when the actual value lies between the first threshold value and the third threshold value or between the second threshold value and the fourth threshold value, and (ii) a second signal characteristic when the actual value lies above the third threshold value or below the fourth threshold value;
outputting the monitoring signal to an interface with the at least one electrical load and/or with a control unit of the vehicle; and
activating, using the first signal characteristic, at least one safety function of the vehicle that maintains an active operating state of the at least one electrical load, and deactivating, using the second signal characteristic, the at least one electrical load of the vehicle.
