This final paper describes the proposed mechatronic system for automatic parking of vehicles in a marked closed arbitrary space. For these purposes, a research of published commercially known systems for automatic parking of vehicles was done and the method of programming the selected PLC was explained, the functions of the control program, components and elements of the system, and finally the advantages and limitations of the proposed system were highlighted. The control program parks the vehicle in an arbitrary parking space by connecting data from the built-in sensors and cameras for recognizing parking spaces by precisely controlling the vehicle with the help of mechatronic actuators. This paper compares different commercial automatic parking systems from Tesla, BMW and Audi. The author concludes that the automatic parking function significantly contributes to convenience, time saving and traffic safety, despite the great technical challenges.
