The paper provides a simple parking path programming\nstrategy for automatic parking system (APS). The control\nstrategy employs the minimum turning radius of the vehicle\nby means of a distance infrared sensor to determine the\nparking path. The programming strategy can simplify the\nanalysis of the parking path; therefore, there is no need to\napply any expensive sensors and complex mathematical\ncalculation to determine the parking path. In the experiment,\na four- wheel model vehicle has been tested in combination\nwith an microprocessor (ARM 9) and a distance infrared\nsensor. A vehicle could be safely and correctly parked in the\nparking space by following these routes.
