Generally, in order to verify the degree of tire wear or abnormal wear, a driver or an auto mechanic checks the degree of tire wear and the existence of tire abnormality, directly with the naked eye or by way of using a gauge equipment. In case of such verification, individual subjective judgments may be involved or a driver may suffer heavy burdens to expend the time and cost for using the wheel alignment equipment. Therefore, this thesis will use a number of laser sensors to check the existence of abnormal wear and the degree of wear on each tire and develop a system checking the sides of tires to receive the tire information, so that subjective judgments may be overcome and objective and accurate judgments may be rendered.

일반적으로 타이어의 정보를 알기 위해서는 운전자나 정비사가 직접 타이어를 육안으로 타이어의 측면의 정보를 확인하거나, 타이어의 측면을 사진을 찍어 확인하는 방법을 이용한다. 이러한 방법은 개개인의 직접 인터넷으로 정보를 알아 봐야하고, 사진 찍을때의 환경에 따라 정보가 틀려져, 이는 개개인의 긴간적인 부담과 정보의 오차가 발생하게 된다. 그래서 본 논문에서는 측면의 타이어 정보 인식을 더욱 더 정확하고 시간적인 부담을 줄이기 위해 범위 레이저 센서를 이용하여 타이어의 옆면을 체크 하는 시스템을 개발하여 객관적이고 정확한 판단을 내릴 것이다.

In order to check the status of tire wear, a driver or auto mechanic generally checks tires with the naked eyes or with a coin. Those are easy for anyone but make it difficult to obtain precise information. But the result is a measure of mechanic wear out due to subjective judgment. Since we can not give correctly measure the stability of the tire. This may lead to an accident of the operator. Therefore, there is a need for a system checking tires precisely, accurately and easily, while making up for the aforementioned defect. This thesis has implemented a system with the aforementioned function. This system tire surface scanner data unit to determine the tread wear on the car and a storage unit for the data save, And a Web service unit allows the user to easily check the information.

Indoor parking garages have concrete-paved inclined ramps, contributing to high tire friction and increased slip angles. Therefore, the abrasion behavior of tire treads on an indoor parking garage ramp differs from those on common asphalt-paved roads, leading to variations in the generated TRWPs. The TRWP densities ranged from low (< 1.1 g cm^-3) to high (> 1.8 g cm^-3), and the degree of mineral particles adhering to the surface of tire wire particles increased with density. The densities and aspect ratios of the TRWPs generated in the parking garage varied depending on the ascent and descent ramps and the slip angles of tires. The TRWPs generated in the parking garage were distributed at a lower density than those produced on asphalt-paved roads and had lower aspect ratios. TRWPs generated from tires at large slip angles mostly exhibited densities below 1.1 g cm^-3 on the ascent and descent ramps in the parking garage. Such low-density TRWPs can be easily resuspended by traffic in the air and may remain suspended in aquatic environments for prolonged periods upon entering rivers and seas.
