Abstract

A method for recognizing a trailer or semitrailer of a motor vehicle which includes activating at least one brake light of the trailer or semitrailer, independently of the driver, measuring a current flowing in a line assigned to the brake light of the trailer or semitrailer and ascertaining the presence or the absence of a trailer or semitrailer on the basis of the measured current.
