Method for recognizing short-circuit or failure of electrical conduction for vehicle, involves up-modulating signal sample on electrical conduction, which is controlled by line status

摘要

The method involves up-modulating a signal sample on an electrical conduction, which is controlled by a line status. The controlled electrical conduction is carried out as a function of the influence recognition. The signal sample is generated from an overlay of multiple signal samples or a code. An independent claim is included for a device for recognizing short-circuit or a failure of an electrical conduction for a vehicle.
