Autonomous parking assistance system in this paper is confined to the device that reduces the driver’s efforts by carrying through the following three steps instead of driver: searching the vacant lateral space with ultrasonic sensors, calculating parking course to empty parking lot, and steering automatically with using Electric Power Steering (EPS) system. This paper considers the development of algorithm after the first step in autonomous parking assistance system. It is developed the technique that makes parking path having continuous steering profile avoiding collisions with the surroundings found in parallel and perpendicular parking circumstances. And it is designed the technique tracking the path based on simple feedforward-feedback control. The techniques of path-planning and path-tracking are embodied on embedded MCU and tested at the real parking conditions composed of the cars and other objects like as cone, tree, wall and curbstone.

Smart Parking Assistance System(SPAS) is confined to the device that reduces the driver’s efforts by carrying through the following three steps instead of driver: searching the vacant space with ultrasonic sensors, calculating parking course to detected parking lot, and steering automatically with using Electric Power Steering (EPS) system. Now, the manufactures are developing the automatic parking assist system that control automatically not only EPS, but driveline, brake and transmission to increase the driver’s convenience and safety. In this pater, Remote Smart Parking Assist System(R-SPAS) based on ultrasonic sensors is integrated EPS system, driveline, brake and transmission. And it is controlled by smart device automatically. Human Machine Interface (HMI) and smart device display are designed to inform the user of vehicle state, operation, sound. It helps the user visibility and convenience. Especially, we applied the safe functions to avoid collision those although the user doesn’t recognize around obstacles such as a passing vehicle, cart and pedestrian. We verified that performance in parallel and perpendicular park scenarios using a simulation program. Also, the vehicle test results obtained from various environments on smart devices have shown the reliable performance, safety and convenience of R-SPAS.
