Abstract

A sensor for detecting an object or a person in the interior of a vehicle consumes a first average power in a normal operating mode. The power supply for supplying the sensor is monitored. The sensor is operated with a second average power which is reduced in comparison with the first average power if the power supply is considered as no longer being sufficient for the normal operating mode.
