인터넷을 비롯한 SNS의 발달은 렌터카 서비스를 IT기반의 카쉐어링 서비스로 변모시켰다. 카쉐어링 서비스는 비대면 온라인으로 자동차를 빌릴 수 있는 서비스로써 혼술, 혼밥에 익숙한 청년층이 선호하는 서비스가 되었다. 스마트폰을 이용하여 차종과 시각을 예약하고 가까운 지정 주차장에 가서 스마트폰으로 자동차문을 열고 운전을 하며 주행 거리만큼 후불 결재를 하는 아주 편리한 서비스이다. 그러나 운전 면허증이 없는 미성년자가 지인이 빌린 차를 대신 운전할 수도 있고, 카쉐어링 업체에 회원가입 할 때에 등록한 면허의 상태가 차를 빌리거나 운전 중에 면허 정지나 취소로 변동될 수 있으며 심지어는 음주상태인 사람이 차를 빌려 운전을 할 수도 있는 등의 문제점이 있다. 본 논문에서는 이러한 문제점을 해결할 수 있는 방안을 연구하였으며 제안한 방법은 가급적 카쉐어링 서비스 업체의 투자비용과 사용자의 불편함을 줄일 수 있는 방법이며 기존의 방법과 비교 및 분석하였다. 현재 카쉐어링 업체들은 회원 가입시에 휴대폰 본인인증, 본인 면허증등록, 본인 명의결제 정보등록을 철저히 요구하고 있다. 제안한 방법중에 '고객과의 영상통화 및 질의응답' 방법은 부적격한 다수의 운전자들이 돌아가면서 운전하는 것까지 막을 수 있으며 '보호자에게 문자전송' 방법은 간단한 방법이지만 효과적인 예방 방법이다. 제안한 방법이 효율적으로 활용되려면 카쉐어링 업체의 적극적인 운영과 정부의 정책이 뒷받침되어야 할 것이다.

In this paper, we design and implement an Application based on android platform, which can control arduino Prime Smart Car using Bluetooth communication. This Application consist of Bluetooth communication module, manual mode module, and line-tracer mode module. In the Bluetooth communication module, it checks the on/off status of Smartphone Bluetooth. If Bluetooth status is off, it activates Bluetooth, selects the corresponding device from Bluetooth device list, and connects with a pair. In order to reduce coding time, we implements Bluetooth communication using inherited class from android Bluetooth package. In the manual mode module, it implements six direction moving button and stop button, which can control arduino Prime Smart Car. In the line-tracer mode module, it implements Prime Smart Car with self-driving function using TCRT5000 sensor. And moving button and stop button is disabled.

It is developed in domestic and position Tilting train's Onboard Cabsignal system at the car of the train follows in the route which comes to be applied and application environment and the scope of function and application of equipment is different applied. The development direction of signal equipment at the domestic car must secure the maintenance conservativeness and a fundamental technique of hereafter. It will reach and to respect standardization of technical power it leads and must be applied development or. Consequently, Domestic it is developed tilting it investigates the application scope of the train. It investigates the development direction of signal equipment at the hereafter car. Currently it researches the signal equipment of top of head of a family enemy conditions grudge. Also, It was improved the scope of application function in following and it considered it researched the quality thing and the signal equipment at the car.

Recently, using GPS and equipment that recognizes the position of the car such a computer system inside the car are very universalized. Specially, the technique that diagnoses troubles and prevents troubles through scanning engine ECU is very popularized also. However, because these data have to be directly transferred and received from the car, in cases of traffic accident such as serious damage or car theft, it is impossible to receive the data at the time of accident. In order to receive and preserve the data safely regardless of these situations, it is possible to provide data for analyzing reasons of accident and prevent accidents from occurring by using wireless communication to receive the transferred information of the car, then saving into a Database system DB, or grasping the situation of the car and the driving pattern of drivers through analyzing stored data. Moreover, due to developing some related services such as providing the information about the real time of the accident, diagnoses of the car and alarms, etc. It is expected to contribute to creating added values.

Lightning is one of hazards affecting the rapid-transit railway system. There are two effects, which are direct lightning surge to electric car line and induced lightning surge. Protection methods for the direct lightning surge are studied with various occasions, however, study of induced lightning surge is insufficient in spite of a large or small effects. In this paper, it is analysed the way that serge voltage is induced to electric car line by lightning strikes. By modeling the propagation process and the coupling phenomenon of electromagnetic wave produced by lightning strikes, it is achieved to make integrative circuit model combined with existing electric car model. The study is conducted into three different waveform of electromagnetic wave produced by lightning; rectangular wave, double exponential distribution wave, triangle wave. It is also simulated that the inducing serge is coupled to electric car line in an arbitrary location. The simulation results in that, when rapidly changing rectangular wave is supplied, maximum power is induced to electric car line.

Kimhae light subway started complete unmanned operation electromotive car starting construction. It stepped on the first step which approaches at time of the unmanned operation electromotive car there is a possibility of doing. During the 30 years, the electromotive car market of domestic developed. Finally we will start into a plan and a production for the initial commerce operation. The Canada unmanned operation electromotive car which we are advancing, It means becomes the good example in the relation technical experts

Due to increasing possession of the car, so car trade is brisk. In the type of trade, new car buying is more than used car. In the used car trade, customer's lose has increasing cause by illegal or opaque trade. It is necessary that considering a counterplan for this problem. In this study, we develop used car trade standard, so customer's lose has decreasing and deducing legal trade of used car.

In this paper, vibration sources of a car-holder are identified and the car vibrations are reduced by structural modification. For vibration identification, vibration signals are measured by an accelerometer when the car is moving. From some experiments and finite element analyses, it is also found that resonances occur because the natural frequencies of the car exist in usual driving speed range. To shift the natural frequencies outside the driving speed range, the connection part is modified to increase stiffness. It is verified that considerable amount of vibration are reduced by the structural modification.

The most important part in automated transport systems is steering control for lane keeping Most of systems developed so far have used the visual information for steering control. In this study, the steering control algorithm based on visual servoing has been developed and tested by applying it on Radio Controlled(R/C) model car equipped with one CCD camera. We also demonstrated the feasibility of using it as a pre-test car before the real car experiment in developing automated vehicles. In order to solve the problem of the limited spave and load of a model car, remote-brained approach has been taken. For steering control of a model car, the PD controller which uses the look ahead offset to generate control input has been implemented and the characteristics of the controller has been explained in view of kinematics. Some experimental results have been also illustrated so as to show the control performance and stability.
