Development of an automatic parking system for vehicle

This research proposes an automatic parking system (APS) with a good maneuver performance for vehicle. The proposed configuration of the APS includes sensors information fusion, position estimation, path planning, and tracking algorithm. The on-vehicle verification demonstrated by means of the control of an electric power steering system for tracking the planned path. Parking space is measured up as the vehicle drives past with the aid of an ultrasonic sensor. And drivers can use a user interactive interface to select the parking space if it is big enough. Then steering movements take place on the basis of the pure pursuit tracking algorithm and the inertial navigation method. Simulation and experiment results show good performance in the verification of our automatic parking system under reverse parking and parallel parking cases, and the parking space requires just 1.5 times longer than vehicle length. Parking maneuvers will become safer and more efficient through the utilization of these advanced safety techniques for automatic parking.
