1. A car washing system for determining a geometric center position of a vehicle positioned within the car washing system, the car washing system comprising:
a traverse which extends transversely to the longitudinal axis of the vehicle and on which a first travel carriage and a second travel carriage are arranged, each of the first and second travel carriages being movable in a longitudinal direction of the traverse;
a first cleaning brush suspended from the first travel carriage;
a second cleaning brush suspended from the second travel carriage, wherein the first and second cleaning brushes are each driven via a brush rotation drive;
a first measuring unit arranged on the first carriage and configured to detect a first travel position of the first carriage;
a second measuring unit arranged on the second carriage configured to detect a second travel position of the second carriage;
a first power sensor configured to detect a first power consumption of the first cleaning brush;
a second power sensor configured to detect a second power consumption of the second cleaning brush; and
a controller configured to:
determine the geometric center position of the vehicle positioned within the car washing system based on the first travel position of the first travel carriage and the second travel position of the second travel carriage detected at a point in time at which each of the first power sensor and the second power sensor detects a changed measurement result.
