Abstract

A method for treating the surface of a vehicle by means of at least one rotating treatment brush. The treatment brush comprises treatment elements, the surfaces of which are brought into frictional contact with the vehicle surface during the treatment. According to the method, a reference measurement is carried out, in which the treatment brush is set in rotation and is moved into a defined position relative to a reference element, such that the surfaces of the handling elements are brought into frictional contact with the surface of the reference element, and in this case the value of the frictional force is measured directly or indirectly. During the treatment of the vehicle surface, the treatment brush is controlled as a function of the value of the frictional force measured during the reference measurement. A system for treating the surface of a vehicle by means of which this method can be carried out.
