1. A method for operating a locking system of a transportation vehicle, wherein time-of-flight measurements are carried out using at least one interior transceiver arranged in an interior of the transportation vehicle and at least one exterior transceiver arranged outside the interior, the method comprising:
determining a position of a key device relative to the transportation vehicle based on the time-of-flight measurements, wherein the determining of the key device position is performed in an interior locating operation in which the position of the key device relative to the transportation vehicle is determined based only on the time-of-flight measurement with the at least one interior transceiver, wherein the determining of the key position relative to the transportation vehicle is performed in an exterior locating operation in which the relative position is determined based only on the time-of-flight measurement with the at least one exterior transceiver, and wherein the interior locating operation and the exterior locating operation are carried out separately;
performing an operating function of the locking system based on the determined position of the key device relative to the transportation vehicle, wherein the relative position determined during the interior location operation and/or the exterior location operation is selected as the basis for performing the locking system operating function to be performed, wherein the locking system operating function is a locking of the transportation vehicle, an unlocking of the transportation vehicle and/or a starting of a drive motor of the transportation vehicle; and
validating the time-of-flight measurements carried out during the interior location operation and/or the time-of-flight measurements carried out during the exterior location operation, wherein a verification is performed during the validation to determine whether a signal from the at least one interior transceiver and/or the at least one exterior transceiver has been is reflected during the time-of-flight measurement.
