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.

The studied area is lobated in the central part of Kwang-Yang, Chullanamdo, which is in the south west of the Gyeongsang basin, The geology consists of the Pre-Cambrian Jirisan gneiss complex as its country rock, covered with the Gyeongsang system sedimentary rock giving unconformity in the Cretaceous period, and is intruded by volcanic rocks and plutonic jgneous rocks. These deposits are fissure filling hydrothemal ore deposits which were formed through fissure with the strike N 20^˚~50^˚E and the dip 70^˚~85^˚SE in the Pre-Cambrian Jirisan gneiss complex. They consist of gold, silver, and quartz veins. Ore minerals are chalcopyrite, arsenopyrite, pyrrhotite, pyrite, galena, sphalerite, native gold, bornite, and covellite. The source rock of the ore minerals is granite porphyry, plutonic igneous rocks intruded in the late Cretaceous period. The method of study is as follows: 150 pure rock samples and 50 ore samples were picked up around the deposits and outcrops, and classified according to the distributed areas and their kinds. 80 thin sections out of 150 rock samples and 40 polished sections out of 50 ore samples were made and a modal analysis were made of them each. And 10 out of the thin sections were made chemical analysis. 5 out of the polished sections were made X-Ray diffraction analysis, which made a verification of what kind of ore minerals are contained in them. As a result of the modal analysis, the granite rocks ill the studied area are plotted by quartz monzodiorite, and have the similarity of the Bulgugsa granite rocks, and its gneiss is plotted by granodiorite and is similar to the Hongjesa granite gneiss. From the results to the Hongjesa granite gneiss but are poor in SiO_2 and rich in FeO, MgO and MnO, For this reason, it is thought that these rocks contain the minerals of the garnet group. These rocks belong to the alkali-calcic rock series in the alkali lime index composed by Peacock. By the I-S type classification by White, Chappell(1977) and Hine(1978) and by the A C F diagram and the normative’s Qu-Or-Ab triangular diagram, these rocks originated from sedimentary rocks. The Proportion of the alk:fm of the Niggli mean value is 19:46, and these rocks were possibly generated from before the Bulgugsa granite and Masan granite age. From the AMF diagram these rocks are coincident with the Gyeongsang basin trend in granite and similar to the Hyndmann trend in gneiss. In the AKF diagram and normative Or-Ab-An diagram, the rocks in the studied area are rich in albite, and compared with S.R. Nockold’s world rock mean value, they belong mostly to tonalite and diorite.

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.
