Abstract
In this paper, we present a method putting an automatic parking system for four-wheeled vehicle into practice, using RF-ID (Radio Frequency Identification) chip array as a position sensor. At first, three path generation algorithms to lead the vehicle into an appropriate area which is based on Ackermann’s steering geometry are presented. Secondly, a control system which makes the vehicle follow the generated path is described. Also, it is shown the control system design can be deal with as a linear control system design problem, by setting the vehicle attitude angle as the controlled variable. Simulation results show the proposed method works effectively.
