Abstract

The disclosure relates to an approximate determination of a distance between a wireless key which is assigned to a motor vehicle and a transceiver arrangement which is disposed in or on the motor vehicle. In the course of a ranging cycle, a first first path relating to a first threshold value and a second first path relating to a higher, second threshold value are calculated. Two distances are estimated on the basis of this dual first path calculation.
